Wire Power to the Shelf
Before You Begin
Before wiring power to the shelf, do the following:
1
Remove the clear Plexiglass™ cover.
2
Remove the fuses in the equipment bay fuse panel for each circuit (two circuit, -48V_A and
-48V_B) where the PG-Flex CO battery wires are terminated.
Connect the Frame Ground
Follow the instructions below and refer to Figure 18 to connect the frame ground:
1
Connect one end of the frame ground wire to the grounding lug G1 (frame ground).
2
Connect the other end of the frame ground wire to the CO ground termination point.
Figure 18. Connecting the Frame Ground
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.
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.
The minimum frame ground wire size is 6 AWG.
