Altronix AL175ULX2 Installation Instructions - Manual

Overview:
The AL175ULX2 is a power limited power supply/charger that will convert 115VAC / 60Hz input, into two individual
PTC protected 12VDC or 24VDC output, (see specifications). It must be installed in accordance with National and Local
Electrical Codes and Regulations.

Installation Instructions:
The AL175ULX2 should be installed in accordance with article 760 of The National Electrical Code or NFPA 72 as well
as all applicable Local Codes.
See Terminal Identification Chart on page 3 for a description of each terminal function.
1. Mount the AL175ULX2 in desired location.
2. Connect AC power (115VAC 60Hz) to the black and white flying leads of the transformer. Secure green wire
lead to earth ground. Use 18 AWG or larger for all power connections (Battery, DC output). Use 22 AWG to
18 AWG for power limited circuits (trigger inputs, dry outputs).
Keep power limited wiring separate from non-power limited wiring (115VAC / 60Hz Input, Battery Wires).
Minimum .25” spacing must be provided.
3. Set the AL175UL to the desired DC output voltage by setting switch SW1 to the appropriate position
(Power Supply Output Specification Table).
Note: It is important to measure output voltage before connecting devices. This helps avoid potential damage..
4. Connect battery to terminals marked [+ BAT -] (battery leads included).
Use two (2) 12VDC batteries connected in series for 24VDC operation.
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. When the use of stand-by batteries are desired, they must be lead acid or gel type.
5. Connect appropriate signaling notification devices to AC Fail supervisory relay outputs marked
