Installation Instructions:
The AL300ULXD should be installed in accordance with article 760 of The National Electrical Code or NFPA 72 as
well as all applicable Local Codes.
1. Mount the AL300ULXD in desired location.
2. Connect input power to the transformer. Secure green wire lead to earth ground. (Fig. 1).
For 115VAC input: Connect Yellow and White leads from transformer primary to neutral.
Connect Blue and Black leads from transformer primary to line (Fig. 2).
For 230VAC input: Connect Blue and Yellow leads of transformer together.
Connect White lead from transformer to neutral.
AL300ULXD - Power Supply/Charger Rev. 062101

Connect Black lead from transformer to line (Fig. 2).
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).
Keep power limited wiring separate from non-power limited wiring (115VAC 50/60Hz or 230 50/60Hz Input,
Battery Wires). Minimum .25” spacing must be provided.
3. Connect devices to be powered to terminals marked [--DC +] (Fig. 1).
Note: It is important to measure output voltage before connecting devices. This helps avoid potential damage.
4. 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).
5. Connect appropriate signaling notification devices to AC Fail & Low battery (Fig. 1) supervisory relay outputs.
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 600mA.
Note: Expected battery life is 5 years, however it is recommended changing batteries in 4 years or less if needed.
