Installation Instructions:
Wiring methods shall 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.
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 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. 7-8).
2. The power supply is pre-wired to the ground (chassis). Connect main incoming ground to the provided green
grounding conductor lead. Connect unswitched AC power (115VAC / 60 Hz to terminals marked [L, G, N]
(Fig. 1, pg. 3)
. Use 14 AWG or larger for all power connections (Battery, DC output, AC input). Use 22 AWG to
18 AWG for power limited circuits (AC Fail/Low Battery reporting).
3. Set the unit to the desired DC output voltage by setting SW1
(Fig. 1b, pg. 3)
to the appropriate position
(Power Supply Voltage Output Selections Chart, pg. 3).
4. Measure output voltage before connecting any devices to ensure proper operation. Improper or high voltage will
damage these devices. When servicing the unit, AC mains should be removed.
5. Connect devices to be powered to terminals marked [- DC +] (
Fig. 1, pg. 3
).
6. For Access Control applications, batteries are optional. When batteries are not used a loss of AC will result in
the loss of output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel type.
7. Connect appropriate signaling notification devices to AC FAIL & BAT FAIL
(Fig. 1a, pg. 3)
supervisory relay outputs.
Note:
When used in fire alarm, burglar alarm or access control applications, “AC Fail” relay should be
utilized to visually indicate that AC power is on
(Fig. 1c, pg. 3)
.
8. Please insure that the cover is secured with the provided Key Lock.
Wiring:
USE 14 AWG or larger for all power connections.
Note:
Take care to keep power-limited circuits separate from non-power limited wiring (115VAC, Battery).
