Installation Instructions
Wiring methods should be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, and with all local codes and authorities having jurisdiction. Product is intended for indoor use only.
- 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 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.
- Secure enclosure to earth ground.
- Slide Power ON/OFF switch t o OFF position.
- Set SW1 on the power supply board to the desired DC output voltage.
- Probably Voltage Output Specification Chart.
- Connect AC circuit (115VAC or 230VAC, 50Hz/60Hz as follows
- Green branch wire connects to ground lug .
- Line and Neutral to the connector on power supply board marked L, N respectively.
- Use 18 AWG or larger for all power connections Battery, DC output.
- Use 22 AWG to 18 AWG for power-limited circuits AC Fail/Low Battery reporting.
- Slide [Power ON/OFF] switch to ON position.
- Measure output voltage before connecting devices. This helps avoiding potential damage.
CAUTION
Do not touch exposed metal parts. Shut branch circuit power before installing
or servicing equipment. There are no user serviceable parts inside. Slide

If stand-by battery batteries are connected, the DC output remains on.
LED Diagnostics
Red DC | Green AC | Power Supply Status |
---|---|---|
ON | ON | Normal operating condition. |
ON | OFF | Loss of AC. Stand-by battery supplying power. |
OFF | ON | No DC output. |
OFF | OFF | Loss of AC. Discharged or no stand-by battery. No DC output. |
