. The terminal
block provided on /x1 units accepts wire ranging from 18
to 12 AWG or 2.5 mm
2
. 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.
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. See Figure 8.

Failure to do so will allow water to enter and damage all
electronic parts.

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.

(14 AWG) will require a
splice in order to accomodate the terminal block.
1. Install one of the large 1/2-inch 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.
