Perform a Battery Runtime Calibration Calibrating the batteries keeps measurements like runtime and battery charge accurate.

Schneider Electric recommends performing battery runtime calibration at startup, when batteries are replaced, or when changes are made to the battery cabinets.

NOTICE

HAZARD OF EQUIPMENT DAMAGE

• During a runtime calibration the batteries will be at a very low level and therefore not capable of supporting your system load in case of a power failure.

• Batteries will be discharged to 10% capacity and this will result in a low battery runtime after the calibration. Allow a minimum of 8 hours for battery to reach 90% of the capacity after the calibration.

• Repeated battery testing or calibration can affect the lifetime of the battery.

Failure to follow these instructions can result in equipment damage.

To perform a test, the following conditions must be present:

• The batteries must be 100% charged.

• The load percentage must be at least 10% and must not change more than

20% during the test. Example: if the load is 40%, it must not vary more than +/- 8%.

• The bypass supply must be available.

• The UPS Mode must be Normal Operation.

• The System Mode must be On.

1. From the home screen on the display select UPS System > Configuration > User Configuration > Battery Test Settings to access the Battery Test Settings screen.

2. Tap Start to begin the battery runtime calibration. You can tap Cancel to stop the calibration. The status of the runtime calibration is shown under Runtime calibration status.

990-2748M-001 15

Set the Battery Self-Test Settings To start a self-test:

• The battery must be more than 50% charged.

• The load percentage must be at least 10%.

• The runtime available must be more than 2 minutes.

• The bypass supply must be available.

• The UPS mode must be in normal operation or ECO mode.

• The System mode must be On or ECO mode.

The battery self-test simulates battery operation. If the utility/mains power fails during the test, the test stops and the UPS supplies battery power.

The test detects any weak or inoperable battery cells.

The following criteria should be met to ensure that the test detects any weak battery cells:

• The total discharge current to the load from both the positive and negative sides of the batteries needs to be at least half of the rated battery Ah. For example, if you have 18 Ah of batteries, more than 9 A must be drawn by the load from each battery side.

• Both the positive and negative battery voltage must be lower than 280 V for longer than 16 seconds.

The test lasts for approximately 10% of the available runtime.

NOTE: The test will discharge all batteries by 10%.

1. From the home screen on the display select UPS System > Configuration > User Configuration > Battery Test Settings to access the Battery Test Settings screen.

Access a Configured Network Management Card NOTE: The below procedure shows how to access the Network Management Card (NMC) from a web interface. It is also possible to use the following interfaces: Telnet and SSH, SNMP, FTP, and SCP. See the NMC Installation Manual for more information.

NOTE: Ensure that only one NMC in the entire system is set to synchronize time.

Use Microsoft Internet Explorer® (IE) 7.x or higher (on Windows operating systems only) or Mozilla® Firefox® 3.0.6 or higher (on all operating systems) to access the Web interface of the NMC. Other commonly available browsers may work but have not been fully tested by Schneider Electric.

You can use either of the following protocols when you use the Web interface:

• The HTTP protocol, which provides authentication by user name and password but no encryption.

• The HTTPS protocol, which provides extra security through Secure Socket

Layer (SSL): encrypts user names, passwords, and data being transmitted, and authenticates NMCs by means of digital certificates.

NOTE: In v6.8.0 and higher, HTTP is disabled and HTTPS is enabled by default.

To access the web interface and configure the security of your device on the network:

1. Address the NMC by its IP address (or its DNS name, if a DNS name is configured).

2. Enter the user name and password.

NOTE: The default user name and password are apc at first login. In v6.8.0 and higher, you will be prompted to enter a new password after you log in.

3. To enable or disable the HTTP or HTTPS protocol, use the Network menu on the Administration tab, and select the Access option under the Web heading on the left navigation menu.

Determine if you need a Replacement Part To determine if you need a replacement part, contact Schneider Electric and follow the procedure below so that the representative can assist you promptly:

1. In the event of an alarm condition, scroll through the alarm lists, record the information, and provide it to the representative.

2. Write down the serial number of the unit so that you will have it easily accessible when you contact Schneider Electric.

3. If possible, call Schneider Electric from a telephone that is within reach of the display so that you can gather and report additional information to the representative.

4. Be prepared to provide a detailed description of the problem. A representative will help you solve the problem over the telephone, if possible, or will assign a return material authorization (RMA) number to you. If a module is returned to Schneider Electric, this RMA number must be clearly printed on the outside of the package.

5. If the unit is within the warranty period and has been started up by Schneider Electric, repairs or replacements will be performed free of charge. If it is not within the warranty period, there will be a charge.

6. If the unit is covered by a Schneider Electric service contract, have the contract available to provide information to the representative.

Return Parts to Schneider Electric To return an inoperable part to Schneider Electric, contact Schneider Electric customer support to obtain an RMA number.

Pack the part in the original shipping materials, and return it by insured, prepaid carrier. The customer support representative will provide the destination address.

If you no longer have the original shipping materials, ask the representative about obtaining a new set.

• Pack the part properly to avoid damage in transit. Never use styrofoam beads or other loose packaging materials when shipping a part. The part may settle in transit and become damaged.

• Enclose a letter in the package with your name, RMA number, address, a copy of the sales receipt, description of the problem, a phone number, and a confirmation for payment (if necessary).
