Chapter 5
Battery Cabinet Installation
If you are not installing optional external battery modules (EBM), continue to "UPS Startup" on page 45.
Only qualified service personnel (such as a licensed electrician) should perform the battery cabinet
installation. Risk of electrical shock.
Before connecting an external battery cabinet to the UPS cabinet or to another external battery
l
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.
Remove all battery packs in the UPS cabinet and/or battery cabinet to ensure DC voltage is
l
removed from the internal DC buses (see Chapter 2, "Securing the UPS in the Rack" on
page 14).
In the UPS cabinet, the proper location of cabinet-to-cabinet DC wiring is on the lower left of the
l
rear panel.
In the external battery cabinets other than the P-103002494, this wiring installs into the rear
l
panel where the DC emergency disconnect switch is located.
For the P-103002494 external battery cabinet, this connection is on the lower left of the rear
l
panel.
Do not connect the EBM AC input to the UPS output
l
Note that the front lower left slot of P-103002494 is solely for AC input for charger modules.
l
Prepare the EBM cabinet:
NOTE 1 The external battery cabinets are the same dimensions as the UPS cabinets. Refer
to Chapter 2, "UPS Setup" on page 9 for unpacking and cabinet setup.
NOTE 2
If you are installing multiple EBM(s) upstream to the UPS, repeat the setup as
described in this section.
1.
Open the carton containing the external battery cabinet cable assembly and position it in the desired
location next to the UPS.
2.
If you are rack-mounting the EBM cabinet, refer to the UPS rack-mount installation procedure (see
Chapter 2, "Rack-Mount Installation" on page 12). If not, proceed to the next step.
3.
Install the anchor brackets to the floor if applicable (see Chapter 2, "Anchor Bracket Installation
(Twelve-Slot Cabinet Only)"
NOTE 1 The P-103002494 is the only external battery cabinet that can accommodate a super
charger module.
NOTE 2
Only the lower left slot (facing you) of the P-103002494 can accommodate a super
charger module. If the slot is not used for super charger module, the remaining slot
may be used for a battery module.
NOTE 3 The P-103002494 12-slot external battery cabinet must be wired for input power
from the utility AC power supply.
