Cable Clamp in
Housing
10: Insert the knurled head screw (6) through the housing socket (7) casting as shown in
11: Install the shorter green ground wire (18) onto the screw. The prongs on the crimped connector
should be toward the casting.
12: Install the ground spring (29) onto the screw and secure it with the Southco flat retaining ring
(26). Install the Southco ring with its prongs away from the casting.
Note:
13: Lay the leads in the bottom half of the cable clamp (located in the housing socket casting [7]),
making sure that the fiberglass sleeving extends slightly past the screw holes in the housing
socket casting. Install new sleeving if necessary. Then, route the wires as shown in
CAUTION:
14: Install the top half of the cable clamp (8) and secure it with the two screws (22). Tighten the
screws alternately to ensure a solid connection.
Note:
15: Using the four screws (21), attach the handle (14) to the lamp socket assembly. See
16: Place the compression spring (28) on the protrusion on the inside of the index hub. See
17: Insert bolt (23) through spring (28) and through the index hub (4) of the housing socket (7),
joining the two castings as shown in
pieces.
18: Before proceeding, check again to make sure the wires are still positioned as indicated in
Figure 7
19: Press the two castings together firmly so the bottom of the light baffle (3) sits on top of the cable
clamp (8), then install Z lamp knob (11). Hand tighten the knob all the way to the right. See

Use pliers to straighten the Southco retaining ring (26) if it bends when you install it
on the bolt.
You must follow the wire routing diagram to ensure that the socket leads do
not interfere with the lamp focus mechanism.
To ensure that the clamp holds the cable tightly, flatten the cable, then fold over the
sleeving before you install the top half of the clamp. Make sure the top edge of the
cable clamp is even with the edge of the socket to prevent interference with lamp
focus movement. Make sure sleeving is not pinched.
. Adjust if necessary.
.
You must install Z knob as described above to ensure proper lamp focus
travel.
