Installing and Connecting Batteries
Procedure
NOTE: Refer to
as this procedure is performed.
1.
Turn OFF the battery disconnect circuit breaker located on all battery trays. Refer to
for locations. Follow local
lockout/tagout procedures to ensure circuit breakers remain in the off position during installation.
2.
Remove the battery retention bracket as shown in
. To do so, remove the four 1/4-20 x 5/8” bolts and associated
washers.
3.
Slide batteries into the tray, with the battery terminals toward the front as shown in
. Slide batteries into the tray as far
as they will go.
4.
Reinstall the battery retention bracket. Secure with the hardware removed in a previous step. Refer to
for hardware
location.
5.
Connect three links supplied by the battery manufacturer between pairs of battery terminals as shown in
. Use
hardware furnished by the battery manufacturer. Torque hardware to battery manufacturer’s recommendations.
6.
Ensure the battery cable ends in all trays are insulated with sleeving before performing the next step.
DANGER!
In multiple-tray installations, when batteries in one tray are connected, the battery cables in all trays will be
energized. Remove sleeving from and connect one cable at a time. Do not allow a cable end to contact the battery tray or
equipment rack.
WARNING!
In the next step, observe correct polarity. Connect only cables labeled “+” to battery terminals labeled “+”.
Likewise, connect only cables labeled “–” to battery terminals labeled “–”.
7.
Connect the cables found in the battery tray to the battery terminals, “+” to “+” and “–” to “–”. Observe correct polarity. Refer
to
. Secure with hardware furnished with the battery. Torque hardware to battery manufacturer’s recommendations.
NOTE: Three battery temperature probes are provided. Connect a temperature probe to the left-most battery module’s
negative terminal in each battery tray (see
). Connect the temperature probe in the bottom tray to the System Temp
1 input on the system interface board. Connect the temperature probe in the middle tray to the System Temp 2 input on the
system interface board. Connect the temperature probe in the top tray to the Temp 1 input on the IB2-1 board. Refer to
“Temperature Probes” on page 23. In the event there is excess length of the probe wires, coil the wires up and tie in a
convenient location along the path of the battery power cable.
8.
Repeat steps 1 through 7 for any remaining battery trays.
9.
To connect the batteries to the power system, turn ON the battery disconnect circuit breaker located on all battery trays.
