2. Set the AL600ULX to the desired DC
output voltage by setting SW1
(Fig. 1) to the appropriate position
(see power supply voltage
output selections chart).
3. Connect AC power (115VAC 50/60Hz
to terminals marked [L, G, N]
(Fig. 1). Use 18 AWG or larger for all
power connections (Battery, AC input,
DC output). 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
(115VAC / 60Hz Input, Battery
Wires). DC output Minimum .25”
spacing must be provided.
4. Connect devices to be powered to
terminals marked [--DC +] (Fig. 1).
Note: It is good operating practice to
measure and verify output voltage
before connecting devices to ensure
proper operation of equipment.
*Note: Power switch is used to turn
off DC output voltage (However if
battery is connected, its voltage will
appear on the output). It disconnects
the L (HOT) terminal from the rest of
the board. 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.
Connect battery to terminals marked [--BAT +] (Fig. 1). Use two (2) 12VDC batteries connected
in series for 24VDC operation (battery leads included).
6. It is required to connect appropriate signaling notification devices to AC FAIL & BAT FAIL (Fig. 1) supervisory
relay outputs. Use 22AWG to 18AWG wires. AC FAIL will report in 5 minutes. To delay report 6 hours cut
“AC delay” jumper.
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 proper voltage level
(see power supply voltage output specifications chart).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage both at bat-
tery terminal and at the board terminals marked [- BAT +] to insure there is no break in the battery connection wires.
Note: Maximum charging current under discharges is .7 amp.
Note: Expected battery life is 5 years, however it is recommended changing batteries in 4 years or less if needed.
