2. Connect AC power (220VAC 50/60Hz) to the terminals marked [L, N].
Secure ground wire lead to ground lug (Fig. 1, pg. 3).
Use 18 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).
Keep power-limited wiring separate from non power-limited wiring (220VAC 50/60Hz Input, Battery
Wires). Minimum 0.25" spacing must be provided.
3. Measure output voltage before connecting devices. This helps avoiding potential damage.
4. Connect devices to be powered at 5VDC to the terminals marked [+ 5VDC –].
5. Connect devices to be powered at 12VDC to the terminals marked [+ 12VDC –].
6. Connect devices to be powered at 24VDC to the terminals marked [+ 24VDC –].
7. Connect two (2) 12V stand-by batteries.
Note: For Access Control applications batteries are optional. When batteries are not used, a loss of AC will
result in the loss of output voltage. Batteries must be lead acid or gel type if used. Two (2) 12V stand-by
batteries connected in series to terminals marked [+ BAT –] (Fig. 1 , pg. 3).
8. It is required to connect supervisory trouble reporting devices to the outputs marked [AC FAIL, LOW BAT]
(Fig. 1, pg. 3). Use 22 AWG to 18 AWG for AC Fail and Low Battery reporting.
AC Failure will report in 5 minutes.
Unit should be tested at least once a year for the proper operation as follows:

Maintenance:

Under normal load conditions, the DC output voltage should be checked for proper
voltage level (see Terminal Identification Tables).
Under normal load conditions check that the battery is fully charged, check specified
voltage at the battery terminals and at the board terminals marked [+ BAT –] to ensure
that there is no break in the battery connection wires.
Note: Maximum charge current under discharge is 0.7A.
Note: Expected battery life is 5 years; however it is recommended changing batteries
in 4 years or less if necessary.
