Installation Instructions:
Wiring methods should 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.
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, pg. 4) . Secure enclosure to earth ground.
2. Slide [Power ON/OFF] switch t o OFF position.
3. Set SW1 on the power supply board to the desired DC output voltage (Fig. 1b, pg. 3)
(Power Supply Voltage Output Specification Chart) .
4. Connect AC circuit (115VAC or 230VAC, 50Hz/60Hz) as follows: Green branch wire connects to ground
lug . Line and Neutral to the connector on power supply board marked [L, N] respectively.
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).
5. Slide [Power ON/OFF] switch to ON position.
6. Measure output voltage before connecting devices. This helps avoiding potential damage.
CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing
equipment. There are no user serviceable parts inside.
Refer installation and servicing to qualified service personnel.
7. Slide [Power ON/OFF] switch t o OFF position.

Overview:
Altronix SMP3CTX220 and SMP3PMCTX220 power supply/chargers convert 115VAC or 230VAC (working range
198VAC - 256VAC), 50Hz/60Hz input into a regulated 12VDC or 24VDC output with 2.5A of continuous load
current (see specifications).
