Step 13: Lay the leads in the bottom half of the cable clamp (located in the housing socket
casting [1]), 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 Figure 7.
Step 14: Install the top half of the cable clamp (15) and secure it with the two screws (16).
Tighten the screws alternately to ensure a solid connection.
Step 15: Place the compression spring (8) on the protrusion on the inside of the index hub
(6).
Step 16: Insert bolt (17) through spring (8) and through the index hub (6) of the housing
socket (1), joining the two castings. Make sure wires are not pinched between
the two pieces.
Step 17: Before proceeding, check again to make sure the wires are still positioned as
indicated in Figure 6. Adjust if necessary.
Step 18: Press the two castings together firmly so the bottom of the light baffle (2) sits on
top of the cable clamp (15), then install the Z lamp knob (4). Hand tighten the
knob all the way to the right.
Note:
Use pliers to straighten the Southco retaining ring (12) if it bends when you install
it on the bolt.
CAUTION:
You must follow the wire routing diagram to ensure that the socket leads do not
interfere with the lamp focus mechanism.
Note:
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.
CAUTION:
You must install Z knob as described above to ensure proper lamp focus travel.
