Installation
3.
Feed-through Wiring
Use feed-through mounts to feed cabling
through the foot of the housing.
a.
Prior to mounting the camera, remove
the two dome plugs located inside the
housing (see FIGURE 6).
Figure 6: Feed-through Wiring
b.
Screw the two 3/8in. NPT fittings into
the foot of the housing.
c.
Pull the cabling through the fittings and
into the housing. Tighten the fitting to
4.0 N.m to 4.5 N.m (35in.lb to 40in.lb).
This torque rating is approximately 1 to
1-1/2 turns past the point where the
fitting starts to grip the wire. Failure to
do this will result in water damage to all
electronic parts.
d.
Attach the foot to the top bracket of the
mount.
e.
Be sure that the holes in the rear cap are
covered with the rubber plugs provided.
Push in until flush and then release.

Power Connections
Power into the housings is to be supplied using
type UL Standard
SJ
cord (or better)
acceptable for outdoor use. Installation must
conform to acceptable NEC and local codes.
For 24 volt cameras, use the
Recommended
Maximum Cable Lengths
chart for selecting
the proper wire size.

Housings Equipped with 24 Volt Cameras, Heaters,
and Blowers.

NOTE: Wire sizes larger than 2,5mm
2
(14AWG) require
a splice to accomodate the terminal block.
a.
Install one of the large 1/2in. NPT
fittings into one of the holes in the rear
cap.
If using the feed-through option,
ignore this step.
b.
Route the power cable through the
fitting in the rear cap or one of the feed-
through fittings in the foot.
c.
The terminal block accepts wire ranging
from 0,5 to 2,5mm
2
(20 to 14AWG).
When using larger wire sizes, splice to a
smaller size wire at the terminal block
end. The splice may need to be
enclosed in a junction box if it does not
pass through the fittings.
d.
Connection of the safety (earth) ground:
•
A terminal lug is provided for connecting the
external safety (earth) ground to the grounding
post on the PCB bracket assembly
(see FIGURE 7).
•
To attach the safety grounding wire, remove
the nut, washers, internal grounding wire
connection, and the external grounding wire
lug from the grounding post.
•
Strip and crimp the external grounding wire
into the lug.
•
Reattach the grounding connections in the
following order:
1. External grounding wire lug
2. Internal grounding wire lug
3. Flat washer
4. Lock washer
5. Nut
NOTE: For compliance with safety regulations,
the external grounding wire connection must
always be the first connection to be attached,
and the last connection to be removed.
