8. Wiring
8.1
Sections 8.2 through 8.9 describe how to connect the FCS-719. Section 8.10 verifies the installation.
All wiring to the COT shelf is performed on the back side of the backplane.
Follow the provisions of the current edition of the National Electric Code for
wiring external to the PG-Flex product(s).
8.2
Frame Ground and Battery.
Connect the frame ground and battery:
1
Remove the clear Plexiglas
cover.
2
Remove the fuses in the equipment bay fuse panel for the circuits where the PG-Flex CO battery
wires will be terminated.
Follow local grounding practices to ensure a good frame ground connection to
PG-Flex. This frame grounding is required for secondary voltage protection of
the PG-Flex equipment.
3
Connect the frame ground (Figure 4):
a
Connect one end of the frame ground wire to the grounding lug G1 (Frame Ground).
b
Connect the other end of the frame ground wire to the CO ground
termination point.
