1.1.3 Unit Preparation

The Liebert FPC may be removed from the shipping pallet and installed by customer personnel. A typical procedure is:

1. Set the palletized assembly in a level area where there is enough room to roll the Liebert FPC off the pallet onto the floor.

2. Cut the shipping bands.

3. Remove the factory-provided ramp from its shipping position.

One ramp is provided for every five units.

4. Place the ramp adjacent to the pallet to provide a smooth path from pallet to floor.

5. Remove side panels from the Liebert FPC, if supplied. An Allen wrench for the side panels is furnished in the installation packet.

6. Remove the bolts and two mounting brackets holding the unit to the shipping pallet.

Mounting brackets are located on either side of the unit.

7. Roll the unit off the pallet onto the floor.

8. Roll the Liebert FPC to the installation area. For units to be placed on a raised floor, use care when positioning unit over the floor cutout to prevent the casters from falling through the cutout.

1.1.4 Location Considerations

The Liebert FPC should be placed near the load(s) it will supply, preferably within the data center.

Equipment location should employ the shortest output distribution cable runs consistent with logical equipment arrangement and allowance for expansion.

The Liebert FPC is intended for indoor installation in an area with ambient temperatures of 32°F to 104°F (0°C to 40°C) with a relative humidity of 0% to 95% (non-condensing).

Bottom clearance is required for units with bottom entry/exit of cables. This clearance may be provided by a raised floor at least 6" (150mm) high. Figures 1 and 2 show the typical raised-floor cutout dimensions for cables and cooling airflow.

When units are not installed on a raised floor, or if the raised floor will not support the unit, optional floor pedestals may be used. (CSA regulations require Liebert FPC arrangements employing a raised floor. Non-raised floor applications are not CSA approved.) Units with top cable exit provisions do not require bottom clearance.

1.1.5 Floor Pedestal Installation

Floor pedestals are optional equipment that provide clearance for bottom cable entry or exit for Liebert FPC units not installed on raised flooring. The pedestals are adjustable over approximately 3-1/2" (89mm) to allow leveling the Liebert FPC and minor adjustments in the unit’s installed height.

1. Insert the pedestal threaded shaft into the pedestal holes in the cabinet base as shown in Figures 1 and 2.

2. Adjust the pedestal height by turning the welded nut/shaft assembly into or out of the pedestal base as required.

3. Lock the height by tightening the jam nut against the pedestal base.

The pedestal may be anchored to the floor by means of the four holes in the base. Locations of floor pedestals are shown in Figures 1 and 2.

NOTE

Floor pedestals may be reverse-assembled for shipping. Before installation, the pedestals should be reassembled as shown in Figure 4. When the pedestal is properly assembled, the washer on top of the welded nut provides a bearing surface for the unit’s weight.

2. Remove the side panel, internal panel and the lower panel bracket from the Liebert FPC.

3. Remove the Liebert FDC side panel and internal panel, if supplied, and align the Liebert FDC with the

Liebert FPC and bolt the units’ frames together (hardware provided by others).

If floor pedestals are used for the Liebert FPC, two additional floor pedestals are required for the outside corners of the Liebert FDC. See Figure 1.

4. Install the lower panel bracket on the opposite side of the Liebert FDC cabinet.

5. Make electrical connections. For details, see the Electrical Field Connections drawings supplied with the unit.

6. Install the Liebert FPC side panel on the Liebert FDC cabinet.

1.2.2 Distribution Cabinet Electrical Connections

Five field-supplied conductors (3-phase conductors, neutral and ground) are needed to connect the Liebert FDC cabinet to the Liebert FPC cabinet in the field.

For Liebert FPCs with transformers, the distribution cabinet phase conductors are connected directly to the transformer terminals:

• Phase A to X1

• Phase B to X2

• Phase C to X3

The Liebert FDC’s neutral and ground conductors are connected to the Liebert FPC’s neutral busbar and main ground busbar (see unit wiring diagram for location).

For Liebert FPCs without transformers, the distribution cabinet phase and neutral conductors are connected to the corresponding output power distribution terminal blocks inside the Liebert FPC. The distribution cabinet ground conductor is connected to the main ground busbar.

For Liebert FPCs with VPMP monitoring, route each distribution cabinet conductor through the appropriate current transformer (CT) in the Liebert FPC.

NOTE

Distribution cabinet conductors must pass through the current transformers in the same direction as the Liebert FPC panelboard conductors. Use the existing Liebert FPC panelboard wiring for reference.

Vertiv | Liebert® FPC™ 15kVA-300kVA User Manual | 9

1.3 Power and Control Wiring

Power and control wiring should be installed by licensed electricians. All power and control wiring must comply with the NEC and applicable local codes.

1.3.1 Input Power Connections

If the Liebert FPC is furnished with a main input junction box, input power connections are made as detailed in 1.3.2 - Junction Box Installation.

If a junction box is not furnished, the input power feeder is connected to the main input circuit breaker located inside the Liebert FPC. (See Figures 5 through 7.)

To minimize electrical disturbances from other loads in the building, the 3-phase power input to the Liebert FPC should be supplied directly from the service entrance or other power source (a dedicated power feeder).

The input feeder circuit should be sized in accordance with the NEC and any local building codes to ensure the feeder’s ability to safely carry the system’s full load current, including losses.

Input feeder conductors should be sized for no more than 2% voltage drop. If operation at undervoltage conditions for extended periods of time is desired, the input feeders must be oversized.

Typical conductor size data is shown in Table 4. All connections must comply with the NEC and all other applicable codes.

For units with a transformer, the main input feeder should consist of 3-phase conductors and one (safety) ground conductor (3W + G).

For units without a transformer, the main input feeder must consist of 3-phase conductors, one neutral and one (safety) ground conductor (4W + G).

WARNING

Risk of electric shock and arc flash. Can cause injury and death.

Verify that all incoming line voltage (power) and low-voltage (control) circuits are de-energized and locked out before installing cables or making connections, whether in the junction box or in the Liebert FPC.

1.3.2 Junction Box Installation

Main input (power) and low-voltage (control) junction boxes are available for the Liebert FPC to simplify customer connections.

The junction boxes, if used, can either be shipped with the system or can be advance-shipped for installation during the roughing-in stage of new construction.

Liebert supplies flexible, 10-foot-long (3m) conduit with cables for connecting the junction boxes to the unit. The junction boxes should be installed a maximum of 8 ft. (2.4m) from the feeder entrance of the unit.

Liebert recommends centering the junction boxes under a floor tile that is easily removed.

Junction box connections must be installed in compliance with the NEC and all other applicable codes.

Typical junction box connections are shown in Figure 14 and described in 1.3 - Power and Control Wiring.

WARNING

Risk of electric shock and arc flash. Can cause injury and death.

Verify that incoming line voltage (power) and low-voltage (control) circuits are de-energized and locked out before installing cables or making any connections in the junction box.

1.3.3 System Grounding

The performance and safety of any power conditioning system depend on proper grounding.

Figure 10 shows the typical grounding arrangements for the Liebert FPC.

Equipment Grounding Equipment grounding is primarily for safety. Correct implementation of grounding also enhances equipment performance. All power feeders must include equipment grounding means as required by the NEC and local codes.

An insulated ground conductor is recommended to be run in each feeder conduit. Ground conductors must be at least the minimum size per NEC Table 250-66. Larger wire sizes may be used for increased system performance.

If the input power feeder conduit is used as a grounding conductor, adequate electrical continuity must be maintained at all conduit connections.

Signal Reference Grid If the unit is used to supply power to a computer room or area that is equipped with a signal reference grid or a grounded raised-floor stringer system, a grounding conductor should be connected from the system ground bus to the grid or floor system. This conductor should be stranded or braided #8 AWG or larger, and as short as practical. Less than 3 ft. (1m) is recommended.

! WARNING

Risk of electric shock. Can cause equipment damage, improper operation, injury and death.

Isolating bushings must not be used in a metal conduit run. These busings might prevent the system from being properly grounded.

1.3.4 Grounding Electrode Conductor for Liebert FPC’s with Transformer Required by code—The Liebert FPC with transformer must be grounded according to the safety practices of NEC 250-26. A local grounding electrode conductor is recommended in addition to the equipment safety ground which is normally run with the input power conductors. (See Figures 5 through 7.)

As shown in Figure 10, the grounding electrode conductor is run from the unit to the nearest effectively grounded location (listed in order of preference):

• Building steel

• Metal water pipe

• Other made grounding electrode

The grounding electrode conductor’s size is based on the secondary circuit conductors. Table 10 shows the minimum recommended grounding electrode conductor according to the NEC (Table 250-66).

Recommended methods for running the grounding electrode conductor (arranged by preference for system performance; as acceptable by local and other applicable codes):

• Outside of conduit (where not subject to damage)

• Inside non-metallic conduit

• Inside non-ferrous conduit

• Inside ferrous conduit, bonded to the ferrous conduit at both ends, as acceptable by local and other applicable codes

1.3.5 Output Power Connections

Output circuit breaker(s) and/or panelboards with ground and neutral provisions are provided inside the unit for connecting load(s) as required. (See Figures 5 through 7.)

Flexible output distribution cables for use in data processing areas under a raised floor are optional and may be factory-supplied. Cable lengths and layout should be well-planned:

• Cable access—Cable routes should follow aisles between equipment. This will ease access to cables for installation, routine inspection and alterations.

• Cable length—Measure the distance to the load equipment following right-angle paths, rather than diagonally or directly. Always measure to the extreme far side of the equipment with respect to the unit to ensure adequate cable length.

• Air circulation—Prevent restriction of airflow under the raised floor by running the flexible conduits flat on the subfloor, in parallel paths.

For best performance, the Liebert FPC should be installed as close as practical to the load.

Initial system output loading should be between 50% and 75% of rated capacity. This allows the addition of loads without immediately investing in another power conditioner. The high partial-load efficiency of the Liebert FPC permits such sizing without imposing an energy-use penalty during initial operation.

Balancing of loads is good design practice on any 3-phase system. Accordingly, each distribution panel is load-balanced at the factory, based on output branch circuit breaker sizes. All additions to the system should be arranged so as to preserve this balance.

Code Compliance—All output cables and connections must comply with the NEC and all other applicable codes.

Padlock-Off Provisions—All output cables without receptacles that are hard-wired to the load equipment must be equipped with a padlock-off accessory for the output circuit breaker. The padlock-off accessory is to be used to lock-out and tag the circuit breaker when service is performed on the hard-wired load equipment in accordance with OSHA safety rules.

WARNING

Risk of electric shock and arc flash. Can cause injury and death.

Verify that all incoming line voltage (power) and low-voltage (control) circuits are de-energized and locked out before installing cables or output breakers or making connections, whether in the junction box or in the unit.

Verify that incoming line voltage circuits are de-energized and locked out before installing output breakers and cables.

1.3.6 Control Wiring Connections

Liebert power conditioning systems have provisions for external shutdown control from Remote Emergency Power Off (REPO) stations. Figure 12 is a simplified diagram of the shutdown circuitry of the Liebert FPC.

Low-Voltage Control Circuit Control wiring connections must comply with the NEC and all other applicable codes.

As shown in Figure 12, the control circuit operates on 24VDC. The shutdown device (represented by the REPO switch) activates a low-current, 24VDC relay that in turn operates the shunt-trip mechanism. The shunt-trip solenoid opens the Main Input Breaker, which de-energizes the power center.

Multiple-Unit Shutdown When more than one power center is installed by the user, a typical requirement is that actuation of a single device (REPO for example) must shut down all power centers. The low-voltage control circuits of all standard Liebert FPC systems are designed to meet this requirement.

External Control Wiring Connections External control wiring connections for remote shutdown, alarm, and/or monitoring are made to the low-voltage junction box (if used) or to the adapter board terminal strip located inside the unit.

Control wiring connections vary with the type of monitoring system furnished with the unit.

Typical control wiring configurations are shown in Figures 12 through 15.

WARNING

Risk of electric shock and arc flash. Can cause injury and death.

Verify that all incoming high-voltage (power) and low-voltage (control) circuits are de-energized and locked out before installing cables or making connections, whether in the junction box or in the unit.

1.3.7 Adapter Board

The Adapter Board (AB) provides customer interface to the Liebert FPC monitoring systems for units without Low-Voltage Junction Box. Connections are made to terminal strip TB1 for Remote Emergency Power Off (REPO) switches, summary alarm contacts and customer alarms (VPMP monitoring). The AB is mounted on top of the monitoring enclosure inside the top right corner of the unit.

A field-selectable switch (S1) on the AB allows the VPMP to be set up for either Manual or Auto restart. The factory default setting is Manual.

• Manual Restart allows for an orderly supervised startup after power failure. The control circuit automatically energizes the shunt trip mechanism of the main input breaker upon sensing output voltage failure.

• Auto Restart deactivates the Manual Restart function. In Auto Restart mode, the main input breaker does not trip due to power failure and the unit will restart when power is restored.

If two Liebert LDMF systems are provided, the summary alarm contacts from each Liebert LDMF are tied to the Customer Summary Alarm on the adapter board.
