Refer to Figure 5.8 as this procedure is performed.
Removing the Distribution Panel
1. Open the distribution cabinet’s front door by turning the latch in the counterclockwise position (system’s in a relay rack), or
open the system’s enclosure door.
2. Remove the plastic shield covering the circuit breakers or fuseholders on the panel to be removed by loosening the screws
holding the shield and sliding the shield upwards.
3. Disconnect and insulate all load wiring from the circuit breaker or fuse positions.
4. Remove all load return wiring from the ground busbar (if present).
5. Locate the in-line FA/CBA connector located near the back of the panel, and separate the connector halves.
6. Refer to Figure 5.8 and remove the hardware securing the panel’s ground busbar (if present) to the distribution cabinet’s
busbar.
7. Refer to Figure 5.8 and remove the hardware securing the panel’s system load distribution busbar to the distribution cabinet’s
busbar.
8. For dual voltage load distribution panels, refer to Figure 5.8 and remove the hardware securing the +24V or -58V jumper
leads.
9. Refer to Figure 5.8 and remove the hardware securing the distribution panel to the distribution cabinet. Remove the panel
from the distribution cabinet.
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. Torque per Figure 5.8.
2. For dual voltage load distribution panels, replace the hardware securing the +24V or -58V jumper leads. Torque per
Figure 5.8.
3. Replace the hardware securing the panel’s system load distribution busbar to the distribution cabinet’s busbar. Torque per
Figure 5.8.
4. Replace the hardware securing the panel’s ground busbar (if present) to the distribution cabinet’s busbar. Torque per
Figure 5.8.
5. Locate the in-line FA/CBA connector located near the back of the panel, and plug it into the mating connector half in the
