Installing the Distribution Panel

Note: In the following procedure, before making busbar-to-busbar connections, apply a thin coating of electrical anti-oxidizing compound to the mating surfaces of the busbars.

1)Orient the replacement distribution panel into distribution cabinet, checking to ensure no wires are pinched. Replace the hardware securing the distribution panel to the distribution cabinet (10-32 x 5/8” bolt, #10 flat washer, 4-places).

2)For dual voltage load distribution panels, replace the hardware securing the -48V jumper leads (1/4-20 bolt or nut, 1/4” lock washer, 1/4” flat washer. Torque to 84 in-lbs).

3)For battery distribution panels, replace the hardware securing the panel’s

Battery Busbar to the distribution cabinet’s busbar (3/8-16 x 1-1/4” bolt, 3/8” Belleville lock washer, 3/8” hardened flat washer, 2-places. Torque to 180 in-lbs.)

4)For load distribution panels, replace the hardware securing the panel’s System

Load Distribution busbar to the distribution cabinet’s busbar (1/4-20 x 1” bolt, 1/4” Belleville lock washer, 1/4” Belleville lock washer (concave side of Belleville lock washers face each other), 1/4” hardened flat washer, 2-places. Torque to 60 in-lbs).

5)Replace the hardware securing the panel’s Ground Busbar (if equipped) to the distribution cabinet’s busbar (1/4-20 x 1” bolt, 1/4” Belleville lock washer, 1/4”

Belleville lock washer (concave side of Belleville lock washers face each other), 1/4” hardened flat washer, 2-places. Torque to 60 in-lbs).

6)Locate the in-line FA/CBA connector located near the back of the panel, and plug it into the mating connector half in the distribution cabinet.

7)On panels equipped with shunts, reconnect the shunt leads.

Warning: In the next step, observe correct polarity; otherwise equipment damage will result.

8)On panels equipped with a ground busbar, reconnect the load return or battery return wiring to the ground busbar.

9)Reconnect the load or battery wiring to the circuit breaker or fuse positions.

10)Transfer the plug-in circuit breakers or fuses from the old panel to the replacement panel.

11)Replace the plastic shield covering the circuit breakers or fuseholders on the replacement panel.

12)Verify no Circuit Breaker/Fuse Alarms are active.

13)Close the distribution cabinet’s front door. Turn the latch clockwise to secure the door.
