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 of more of the cable knock-outs,
depending on how many connections will be made.
Knock-outs are shown in Fig. 1 to the right. If
desired, use an optional bushing, grommet, or other
sleeve to protect wires passing through the hole(s).
3. Screw the power supply to the wall or other mounting
surface using 5/32"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
(Fig. 2).
WARNING: Always test output voltage before
connecting devices to the power supply.
5. Connect cameras and other devices to the power
outputs, while observing correct polarity as shown in
Fig. 3. To minimize voltage drop, use 18-guage or
larger wire.
6. If voltage drop is large, adjust the output voltage
trimpot as shown in Fig. 4.
NOTE: The output voltage trimpot changes voltage for
all outputs by ±10%. Test all outputs to ensure
voltage does not exceed device specifications.

• Indoor use only. Do not mount the unit where it may be exposed to weather or high humidity.
• For professional installation only.
• Installation must conform to all local laws and building codes.
For 220VAC input voltage,
locate the input voltage switch
on the bottom of the enclosure. Switch the input voltage
from 110V to 220V as shown in Fig. 5.
