Transformer Requirements
(Recommended Altronix Part #’s)
16VAC / 40VA (TP1640).
16VAC / 40VA (TP1640), 24VAC or 28VAC / 100VA (T2428100).
24VAC or 28VAC / 100VA (T2428100).
Note: Transformers with higher VA ratings may be used for all output voltages above as long as you do not exceed
28VAC or 45VDC.

7. Mount power supply board into the enclosure (see Step 1 and Step 2, pg. 2).
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 three fasteners. Place the enclosure’s upper keyholes over the two
upper screws. Install two lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 2).
Secure enclosure to earth ground.
Set DC output voltage with switches (refer to Voltage Output/Transformer Selection Table).
Connect proper transformer to the terminals marked [AC] (refer to Voltage Output/Transformer Selection Table).
Use 18 AWG or larger for all power connections (Battery, DC output).
Keep power-limited wiring separate from non power-limited wiring (115VAC / 60Hz Input, Battery Wires).
Minimum 0.25” spacing must be provided.
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.
Measure output voltage before connecting devices. This helps avoiding potential damage.
Connect devices to be powered to the terminals marked [+ DC –], carefully observing polarity.
Connect battery to the terminals marked [+ BAT --- ] (battery leads included)
Note: When batteries are not used, a loss of AC will result in a loss of output voltage.
