4–10 INSTALLATION
4.3.2 Single UPS Battery Cabinet/HA32A UPS Installation
The UPS Battery Cabinet chassis should be grounded to the same point as that used for
the UPS cabinet ground. Power cables and control cables should be run through conduits
(local codes may require separate conduits) that can be attached through the bottom rear
portion of the UPS Battery Cabinet.
NOTE
For bottom entry, the shipping supports must be removed and replaced with
the cable entry cover plates on the 45-inch UPS Battery Cabinets (see drawing 7
of the HA3000 20-80 kVA UPS Installation Drawings - EK-HA32X-ID).
Power cable and control wire connections are made inside the back top portion of the
UPS Battery Cabinet (Figure 4–4). To access the interior of the UPS Battery Cabinet,
follow this procedure:
1. Remove the back cover on the UPS Battery Cabinet.
2. Open the UPS Battery Cabinet enclosure doors, right door first. Note the location of
QF1, the battery disconnect circuit breaker.
3. Remove the screw at the top right portion of the left door, which holds it in place.
4. Remove the red insulating panel(s) from the front of the battery rack(s).
5. Remove the top front corner piece from the UPS Battery Cabinet by removing the two
screws that hold it in place. These screws are located in a channel on the top of the
UPS Battery Cabinet.
6. Remove the next portion of the top of the UPS Battery Cabinet by removing the two
screws located inside the ventilation openings at each side of the top of the unit.
7. The remaining top portion of the unit can be removed by forcing it off toward the rear
of the unit.
8. To gain access to the wiring area, which is located inside the UPS Battery Cabinet
at the back top portion of the unit, the pull-out rack assembly must be removed. To
do this, first remove the two bolts that secure the pull-out rack assembly to the sides
of the unit. They are located at the top left and top right side of the pull-out rack
assembly. UPS Battery Cabinets that have two pull-out rack assemblies (45-inches
wide) have three bolts securing them in place. One bolt secures the left pull-out rack
assembly to the left side of the unit in a similar manner to the single pull-out rack
assembly. One bolt secures the right pull-out rack assembly to the right side of the
unit in a similar manner to the single pull-out rack assembly. The third bolt secures
the two pull-out rack assemblies together at the center of the unit. Once the bolts
have been removed, the pull-out rack assemblies can be removed from the unit.
CAUTION
The pull-out rack assemblies are connected to the rear of the UPS Battery
Cabinet enclosure by two power cables, a ground cable, and control wiring.
Exercise caution when pulling out the pull-out rack assembly to avoid straining
these connections.
