7. Mounting
7.1 The PG-Flex COTS mounts in a standard 23-inch CO equipment bay. The shelf has a mounting
height requirement of 7 inches.
1 Align the shelf (Figure 3) universal mounting brackets with the four vertical mounting holes.
2 Install the mounting screws.

8. Wiring
8.1
Sections 8.2 through 8.11 describe how to connect the FCS-719. Section 8.12 verifies the
installation. All wiring to the COTS 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).
Use 12 AWG or larger wire (or multiple wires of a smaller gauge) to ensure good
power connections to PG-Flex.
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 each circuit
(two circuits–that is, -48V_A
and -48V_B
) 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.
