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.
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 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. 8). Secure enclosure to earth ground.
2. Connect AC circuit (220VAC, 50/60Hz) as follows: Green branch wire connects to earth (safety) ground
lug . Line and Neutral to the connector on power supply board marked [L, N] respectively (Fig. 1, pg. 4).
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. Measure output voltage before connecting devices. This helps avoiding potential damage.
Keep power-limited wiring separate from non power-limited wiring (220VAC 50/60Hz Input,
Battery Wires). Minimum 0.25” spacing must be provided.
CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing
equipment. There are no user serviceable parts inside. Refer installation and servicing to qualified
service personnel.
4. Connect devices to be powered:
a. For Power Supply Board: connect to the terminals marked [+ DC –] (Fig. 1, pg. 4).
b. For Power Distribution Module(s): connect devices to be powered to the terminal pairs 1 to 4 marked
[1P & 1N] through [4P & 4N] (Fig. 2, pg. 6) or 1 to 8 marked [1P & 1N] through [8P & 8N]
(Fig. 3, pg. 6), carefully observing correct polarity.
Note: When servicing the unit, AC mains should be removed.
5. 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.
6. Connect appropriate signaling notification devices to terminals marked [AC FAIL] and [BAT FAIL]
(Fig. 1, pg. 4) supervisory relay outputs.
Note: When used in fire alarm, burglar alarm or access control applications, “AC Fail” relay must be used
to provide a visual indication of AC power on.
7. Please ensure 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 (220VAC, Battery).
Maintenance:
Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions the DC output voltage should be checked for the proper
voltage level.
Battery Test:
Under normal load conditions check that the battery is fully charged, check specified
voltage both at the battery terminal and at the board terminals marked [– BAT +] to
ensure that there is no break in the battery connection wires.
Note:
Maximum charging current under discharges is 3.6A.
Note:
Expected battery life is 5 years; however, it is recommended changing batteries in
4 years or less if needed.
