External Battery Cabinet Installation

The Powerware 9150 UPS has either 32 or 48 internal batteries. EBCs

are available for the 48-battery model. Refer to the UPS serial nameplate;

the DC voltage on the nameplate must be 288V to add EBCs.

The internal battery charger can support additional EBCs; however,

additional battery capacity also extends the recharge time.

NOTE A service representativemustchange theBatterySizeparameter in the

nonvolatile memory toreflect the correct numberof batterystringsafter installing

EBCs.

the BYPASS position and turn off the UPS ON/OFF switch (the

position). See Figure 6 on page 23.

2. Verify the circuit breakers on the UPS are in the OFF position.

3. Facing the UPS, place the battery cabinet to the right of the

UPS. Confirm the DC voltage on the nameplate of the UPS and

EBC is 288V.

4. Remove the front panel of each EBC. Lift from the bottom of

the panel and then pull out (see Figure 12).
