3.2.3 SIAC-B Power Wiring Preparation

Read and understand the following notes while planning and performing the installation:

WARNING

As a result of the connected loads high leakage current is possible. Connection to earth ground is required for safety and proper product operation. Do not check SIAC-B operation by any action that includes removal of the earth (ground) connection with loads attached.

● Refer to national and local electrical codes for acceptable external wiring practices.

● For external wiring, use 75°C copper wire. Wire sizes listed in Table 3-2 are for copper wiring only. If wire is run in an ambient temperature greater than 40°C, higher temperature wire and/or larger size wire may be necessary. Wire sizes are based on using the specified breakers.

● Recommended wire sizes are based on NFPA National Electrical Code® (NEC®)70 Table 310.15(B)(16) 75°C ampacity with 40°C ambient correction factors.

● Three-wire SIAC-B models do not use a neutral.

● Refer to NEC Article 250 and local codes for proper grounding practices.

● Phase rotation must be clockwise starting with phase A (rotation A,B,C).

● Per NEC Article 300-20(a), all three-phase conductors must be run in the same conduit. A ground wire must be run in the same conduit as the phase conductors.

● Conduit is to be sized to accommodate three phase conductors and one ground conductor.

● Refer to the appropriate Eaton 93PM UPS Installation and Operation manual for UPS cabinet conduit and terminal specifications and locations.

● Material and labor for external wiring requirements are to be provided by the customer.

● If installing an external maintenance bypass, all feeds to the UPS must have a service disconnect independent of the maintenance bypass power path. Most maintenance bypass solutions provide UPS input feeds derived from but isolated from the maintenance bypass power path. If the maintenance bypass solution being installed does not provide such functionality, DO NOT use a single feeder breaker to supply both the UPS and the maintenance bypass.

● The term line-up-and-match refers to accessory cabinets that are physically located adjacent to the UPS. The term standalone refers to accessory cabinets that are located separate from the UPS.
