Removing CPOD From Panel
1. Disconnect and lock off all power
sources supplying this panel.
2. Remove P1 Panel trim and dead
front.
3. Disconnect/unplug the CPOD data
wire connector from the data rail
connector.
4. If a load wire is present, remove it
from the CPOD terminal.
5. Loosen the terminal screw of the
BQD breaker so that CPOD tang
disengages from the terminal of
the breaker. Do not completely
loosen the screw such that it falls
out of the lug.
6. Pull the CPOD away from the BQD
breaker.
Data Rail
Description
Data rail is a shielded communication
bus that allows communication
among up to 21 CPODs (on one side)
and the I/O printed circuit board.
There are 2 data rails on a lighting
panel. The data rail provides a barrier
to isolate the power wiring from the
Class 2 signal wiring used to operate
the relays. Each CPOD connects to
data rail via a connector that extends
out of the CPOD. The connector has
4 wire leads as described in CPOD
section. On the end of the data rail, a
26 wire ribbon connector is used to
connect data rail to I/O printed circuit
board. There are 3 available data rail
sizes depending on the panel size:
1. 5WG1 716 - 8XY11 - 9" Data rail
for 9 circuits (each side)
2. 5WG1 716-8XY31 - 15" Data rail
for 15 circuits (each side)
3. 5WG1 716-8XY51 - 21" Data rail
for 21 circuits (each side)
