Installation Instructions:
The unit should be installed in accordance with The National Electrical Code and all applicable Local Regulations.
1. Mount unit in 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 three 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. 2)
.
Secure enclosure to earth ground.
2. Set SW1 on the power supply board to the desired DC output voltage
(Voltage Output Specification Chart)
.
3. Connect AC power to terminals marked [L & N], connect ground to terminal marked [G] (if used).
4. Measure output voltage before connecting devices. This helps avoid potential damage.
5. Connect devices to be powered carefully observing correct polarity.
*Note:
Power switch is used to disconnect the L (HOT) terminal from the rest of the board.
When servicing the unit, AC mains should be removed.
