Battery Installation

3.4.4Connecting the Battery Cabinet to the UPS

After the battery cabinet equipment has been positioned and secured for operation and the batteries have been connected, connect the power cables as described below. (See Figure 34.)

1.Verify that all incoming high and low voltage power circuits are de-energized and locked out or tagged out before installing cables or making any electrical connections.

2.Remove the UPS left side panel to gain access to the equipment ground busbar.

3.Remove the external battery terminal block plate on the lower left side of the UPS behind the front door.

4.Remove the battery cabinet front panel to gain access to the connection bars.

5.Connect the safety ground and any necessary bonding ground cables to the copper ground busbar. (example: UPS located on the bottom of the equipment below the power connections).

All cabinets in the UPS system must be connected to the user's ground connection.

NOTE

The grounding and neutral bonding arrangement must be in accordance with the National Electrical Code and all applicable local codes.

6.Connect the system battery cables from the UPS battery terminals (+ N -) to battery cabinet BCB (+ N -) as shown in Figure 34. Be sure that the battery connections are made with the right polarity, and tighten the connections to 44 lb-in. (5 N-m) (M6 Bolt). Do not close the battery circuit breaker before the equipment has been commissioned.

7.Connect supplied auxiliary control cable to pins J10.2 and J10.3 on the U2 monitoring board (see 2.3 - Dry Contacts). Add a jumper wire between J10.3 and J10.4.

3.5Non-Standard Batteries

When batteries other than a matching battery cabinet are used, a remote battery disconnect switch with overcurrent protection is required per the National Electrical Code. Contact your local Liebert sales representative about this option.

Install battery racks, cabinets and batteries in accordance with the manufacturer's instructions.

Verify that the battery area has adequate ventilation and battery operating temperature complies with the manufacturer's specifications and with all applicable national and local codes.

If you have any questions concerning batteries, battery racks or accessories, contact Liebert Global Services at 1-800-543-2378.
