S Before connecting an external battery cabinet to the UPS cabinet or to another external

battery cabinet, verify that all AC input power is removed from the UPS. Open the input

service circuit breaker or turn the external bypass switch to the SERVICE position.

S Disconnect all battery strings in the UPS cabinet and/or battery cabinet to ensure DC

voltage is removed from the internal DC buses. You can remove all battery modules or

unplug each pair of battery modules from the cabinet backplane.

To install an external battery cabinet:

1. Open the carton containing the external battery cabinet cable

assembly.

2. Locate the 3-slot section in the UPS cabinet that contains the

power entrance panel. Unscrew and remove the rear panel of this

section (see Figure 42).
