AC power and DC battery wiring
Due to power-limited/nonpower-limited wiring separation
requirements, it is easier to route and wire the nonpower-limited
AC power and battery conductors before installing the LRMs in
the rails. Nonpower-limited wiring should be routed to the
chassis notches to the left and rear of the cabinet. Power-limited
wiring should be routed to the right and front of the cabinet.
WARNING: Do not energize power until instructed to do so!
1. Connect the AC power source to TB1, line, neutral, and
ground terminals on the 3-PPS/M Primary Power Supply
Heat Sink and the 3-BPS/M Booster Power Supply Heat
Sink(s). DO NOT ENERGIZE THE AC POWER SOURCE
AT THIS TIME!
2. Connect the positive battery lead to TB2-1 and the negative
battery lead to TB2-2. Each heat sink assembly must have its
own pair of 12 AWG (2.5 sq mm) wires going to the battery.
Do not connect the heat sinks assemblies together and run a
common wire to the battery! DO NOT TERMINATE THE
WIRES AT THE BATTERY AT THIS TIME.
WARNING: Do not connect batteries until instructed to do so!
