Installation
Please read the manual thoroughly before beginning installation.
1.
Find a suitable location to install the power supply. The power
supply should be installed out of sight, and in a place
protected from weather and high humidity. The power supply
must have adequate ventilation. Insufficient ventilation may
cause overheating and damage could result.
2.
Remove one or more of the cable knock-outs, depending on
how many connections will be made. Knock-outs are shown in
Fig. 1 to the right. Use one of the included grommets or other
sleeve to protect wires passing through the hole(s).
3.
Screw the power supply to the wall or other mounting surface
using

/

"x1" (4x26 mm) screws and plastic anchors (not
included). First, screw in the top screw(s) and hang the power
supply. Then, if applicable, screw in the bottom two screws to
fully secure the unit in place.
4.
Plug the power cable into the power input socket (see
Overview
, pg. 2).
WARNING:
Always test output voltage before connecting
devices to the power supply.
5.
Connect cameras and other devices to the power outputs,
observing correct polarity (see Fig. 2). To minimize voltage
drop, use 18-guage or larger wire.
6.
If voltage drop is large for any individual output, adjust the
output voltage trimpot for that output (see Fig. 3).
NOTE:
The output voltage potentiometers change the voltage
for their assigned output by ±10%. Test each output to ensure voltage does not exceed
device specifications.
