2. Screw the two 3/8-in NPT fittings into the foot of the
housing.
3. Pull the cabling through the fittings and into the housing.
Tighten the fitting to 4.0 N-m to 4.5 N-m (35 in-lb to
40 in-lb). This torque rating is approximately 1 to 1 1/2
turns past the point the fitting starts to grip the wire. Failure
to do so will result in water damage to all electronic parts.
4. Attach the foot to the top bracket of the mount.
5. Cover the holes in the rear cap with the rubber plugs
provided. Push in until flush and then release.
6.8.4 Power Connections
Power connection into the housings is to be supplied through a
minimum type UL Standard "SJ" cord acceptable for outdoor
use. Installation must conform to acceptable NEC and local
codes. For 24 volt cameras, use the chart below for selecting the
proper wire size.

Note: The use of wire sizes larger than 1,5 mm
splice in order to accomodate the terminal block.
1. Install one of the large 1/2-in NPT fittings into one of the
holes in the rear cap. The terminal block side is preferable. If
you are using the feed-through option, ignore this step.
2. Route the power cable through the fitting in the rear cap or
one of the feed-through fittings in the foot.

ranging from 20 to 14AWG or 1.5 mm
block provided on /X1 units accepts wire ranging from 18 to
12AWG or 2.5 mm . When using larger wire sizes, splice to
2
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.
4. A screw/terminal lug is provided for securing a safety
ground. To attach the safety grounding wire (green 115 volt,
green/yellow 230 volt), first unscrew the terminal lug and
strip and crimp the grounding wire into the lug. Attach the
terminal lug to the bracket using the M4 x 10 screw
provided. (LTC 9480/00 models use a M4 Nut to screw the
lug to the base.) See Figure 8.

5. Pull any excess wire out of the housing and tighten the
fitting to 8.5 N-m to 9.0 N-m (75 in-lb to 80 in-lb). This
torque rating is approximately 1 to 1 1/2 turns past the
point the fitting starts to grip the wire.
