7. MOUNTING
7.1
The COT shelf mounts onto a standard 23" central office frame and requires 7" in height of mounting
space (four vertical mounting units). Shipped with the COT shelf are universal mounting brackets
and mounting screws.
8. WIRING
8.1
All wiring to the COT shelf is done on the backplane. To access the backplane, remove the clear
Plexiglas cover.
8.1.1
To connect the frame ground (Figure 3):
1
Remove the fuse in the equipment bay's fuse panel for the circuit where the PG-Flex central
office battery wire will be terminated until the COT is wired and ready for turn-up.
2
Connect the frame ground:
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.
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 central office ground termination
point.
