AL176220 Series Installation Guide
Overview:
Altronix AL176220 and AL176X220 are power supply/chargers that converts a 220VAC (working range 198VAC -
256VAC), 50/60Hz input into 12VDC or 24VDC output (see specifications). Units must be installed in accordance
with National and Local Electrical Codes and Regulations.

Installation Instructions:
Wiring methods shall 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.
See Terminal Identification Chart on page 3 for a description of each terminal function.
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 three 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, pgs. 7 and 8)
. Secure enclosure to earth ground.
2. Connect unswitched AC circuit (220VAC, 50/60Hz) as follows: Green branch wire (ground) connects to the
terminal marked , Line connects to the terminal marked [L], and Neutral connects to the terminal marked
[N] of the Inlet Appliance Connector. Use 18 AWG or larger for all power connections (Battery, AC input).
Use 22 AWG to 18 AWG for power-limited circuits (DC output, AC FAIL, and LOW BAT supervisory relays).
Keep power-limited wiring separate from non power-limited wiring (220VAC, 50/60Hz Input,
Battery Wires). Minimum 0.25” spacing must be provided.
3. Set the unit to the desired DC output voltage by either removing or leaving the jumper.
(Power Supply Output Specification Table).
4. Measure output voltage before connecting devices. This helps avoiding potential damage.
