Installation Instructions

1. Mount SMP3 board (see back).

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 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. Secure enclosure to earth ground.

3. Set DC output voltage with switches (refer to Voltage Output Selection Table).

4. Connect the transformer (TP1640) to the terminals marked [AC]. 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.

5. Measure output voltage before connecting devices. This helps avoiding potential damage.

6.  Devices to be powered should be connected to the terminals marked [+ DC — ], carefully observing polarity.

7. 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.
