Install Power-Failure Transfer Ground Wire

!
CAUTION:
To avoid contaminating single-point ground, do not connect the ground wire
while the system is powered up.
1. Connect 1 end of a 10 AWG (#25) (2.6 mm
connecting block or to pin 49 of the CAP (cable access panel) associated
with the power-failure transfer panel.
2. Route the opposite end of the wire to an approved ground source and
connect.

Disconnect Cables

1. With the cable retainer in front of you and the part number visible (4B or
4C), locate the slot that is almost vertical. This slot is adjacent to the part
number. Insert a flat blade screwdriver with a 1/4-inch blade into the slot
and twist. The retainer will snap open easily. Remove the cable.
2. Disconnect previously labeled cables associated with the carrier to be
removed.
3. Behind a "DEFINITY style" cabinet, remove the back doors from the
cabinet.
4. Behind a previously upgraded cabinet, remove all of the back panels. (Two
different types of screws hold the back panels to the cabinet. The #10
screws can be removed with a screwdriver or a 1/4-inch socket. The #12
screws can be removed with a screwdriver or a 5/16-inch socket.)
Remove Circuit Packs from Module Control
Carriers A and B
1. To ensure that power units in the "A" and "B" carriers are properly replaced,
label each power unit with its slot number.
2. Disconnect the power cords from the power units in the "A" and "B"
carriers.
3. Remove all circuit packs and power units from carrier "A." Store the circuit
packs in the static-proof packaging.
4. Remove all circuit packs from carrier "B." Store the circuit packs in the
static-proof packaging.
5. Remove the circuit pack blanks from slots that do not contain circuit packs.
6. Remove the front trim plate from the "B" carrier by pulling it straight off.
Then remove the front trim plate from the "A" carrier.
