1) If Battery Trays are Equipped With Circuit Breakers: Turn OFF the Battery
Disconnect circuit breakers located on all battery trays. Refer to Figure 4-18 for
locations.
2) Remove the battery retention bracket as shown in Figure 4-18. 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 Figure 4-18. Slide batteries into the tray as far as they will go.
Note: The battery retention bracket can be oriented two ways to accommodate
batteries of different lengths. A correctly oriented bracket will fit snuggly
against the batteries. If your batteries require the alternate bracket orientation
shown in Detail A of Figure 4-18, remove and reinstall the bullet-shaped
spacers as shown in Detail A before performing the next step.
4) Reinstall the battery retention bracket. The spacers on the bracket should
separate the batteries from each other. Secure with the hardware removed in a
previous step. Refer to Figure 4-18 for washer location.
5) Connect two links supplied by the battery manufacturer between pairs of battery
terminals as shown in Figure 4-18. 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 Figure 4-18. Secure with
hardware furnished with the battery. Torque hardware to battery manufacturer's
recommendations.
8) Repeat steps 1 through 7 for any remaining battery trays.
9) If Battery Trays Are Equipped With Circuit Breakers: To connect the
batteries to the power system, turn ON the Battery Disconnect circuit breakers
located on all battery trays.
