Electrical
All electrical connections are made via the single
corrosion resistant connector on the rear panel
(see
Figure 5
). A mating Bendix
TM
Pigmy connector,
PT06P-18-30SR, or equivalent, is supplied. All but one
of the solder cups accepts 0.5 mm
2
(20-24 AWG) wire.
The larger solder cup accepts wire from a minimum
of 0.5 mm
2
(22 AWG) to a maximum of 1.5 mm
2
(16 AWG). See
Connector Pinouts
for pin connections.
Information on sync and video hookups is found in
the basic camera instructions. Zoom lens models
require a zoom lens control system.

Removing the Camera Cradle
1.
Remove the fill valve cap and attach a dry
nitrogen line to the fill valve. Add a small
amount of nitrogen to the housing to pop the
rear end cap from the housing. The supplied
mating connector can be attached to the 30-pin
connector on the rear of the housing and used
as a handle (see
Figure 7
).
Figure 7: Popping Rear End Cap With Nitrogen
If nitrogen is not available, gently, but firmly
grasp and pull the mating connector to release
it from the housing (see
Figure 8
).
CAUTION: Do not to pull on the cable
harness. Grasp the connector body to avoid
putting strain on the wires at the solder cups
in the connector.
Figure 8: Removing and Reinserting the Camera Cradle

Remove the cradle assembly by pulling it out
of the housing (see
Figure 8
). Keep the edges of
the end cap clean and free of scratches.
3.
If replacing the faceplate or O-ring, remove the
front end plate by first removing the retaining
ring on the front of the housing (see
Figure 10
).
