Enclosure Dimensions (H x W x D approx.):
13.5” x 13” x 3.25” (342.9mm x 330.2mm x 82.55mm).
Installation Instructions:
1. Mount unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes in the
enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place the enclosure’s
upper keyholes over the two upper screws, level and secure. Mark the position of the lower two holes. Remove the
enclosure. Drill the lower holes and install the two fasteners. Place the enclosure’s upper keyholes over the two
upper screws. Install the two lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 6).
Secure enclosure to earth ground.
2. Slide switch to the OFF position (Fig. 1, pg. 3, Fig. 2, pg. 4 or Fig. 3, pg. 5).
3. Set the unit to desired DC output voltage range by setting switch (SW1) on the power supply board to the appropriate
position. Use trimpot to adjust voltage if necessary (Fig. 1, pg. 3, Fig. 2, pg. 4 or Fig. 3, pg. 5).
4. Connect the AC (115VAC 50/60 Hz) to the terminals marked [L] and [N].
Connect earth ground (Fig. 1, pg. 3, Fig. 2, pg. 4 or Fig. 3, pg. 5).
5. Measure output voltage before connecting devices. This helps avoiding potential damage.
6. Connect each DC device to the output terminals 1 through 8 (Fig. 1, pg. 3) or terminals 1 through 16
(Fig. 2, pg. 4 or Fig. 3, pg. 5).
Note: Be careful to observe camera polarity.
7. When batteries are being used the DC output voltage must be adjusted by turning the trim pot VR1
(Fig. 1, pg. 3, Fig. 2, pg. 4 or Fig. 3, pg. 5) clockwise to increase the output voltage to 13.7VDC for 12VDC
operation and 27.1VDC for 24VDC operation.
Connect battery to the terminals marked [-- BAT + ] (battery leads included) (Fig. 1, pg. 3, Fig. 2, pg. 4 or Fig. 3, pg. 5).
Use two (2) 12VDC batteries connected in series for 24VDC operation.
8. Slide switch to the ON position (Fig. 1, pg. 3, Fig. 2, pg. 4 or Fig. 3, pg. 5).
9. Green LED on the PD8/PD8CB or PD16W/PD16WCB board will illuminate when power is present.
10. Upon completion of the wiring secure enclosure door with screws (supplied).
WARNING: To reduce the risk of fire or electric shock, do not expose the unit to rain or moisture.
This installation should be made by qualified service personnel and should conform to the National
Electrical Code and all local codes.
