1. Mount unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes
in theenclosure. 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 the two lower screws and make sure to tighten all screws
(Enclosure Dimensions, pg. 10-12). Secure enclosure to earth ground.
2. Slide switch on PD board to OFF position for models ALTV2416 and ALTV2416CB (Fig. 1, pg. 4).
Turn OFF main switch on all other models (Figs. 2-4, pgs. 5-7).
3. All units are factory set for 24VAC operation.
For 28VAC operation, adjust unit prior to mounting and applying power as follows:
Change the wire position so that the black wire [28V] is connected to the terminal marked [P] and
the yellow wire [24V] is connected to the terminal marked [S].
4. Connect AC power to the black and white flying lead of the transformer(s) (Figs. 1-4, pgs. 4-7).
Use 18 AWG or larger for all power connections.
5. Measure output voltage before connecting devices. This helps avoiding potential damage.
Terminals marked [1P - 8P] are positive of the same polarity.
CAUTION: Determine the maximum operating voltage of the equipment being powered before
adjusting the output voltage.
6. Connect devices to terminals marked [1P - 1N] through [8P - 8N] on PD8/PD8CB board or
[1P - 1N] through [16P - 16N] on PD16W/PD16WCB board (Fig. 3, pg. 6), carefully observing polarity.
7. Slide switch on PD board to ON position for models ALTV2416, and ALTV2416CB (Fig. 1, pg. 4).
Turn main switch on all other models to the "RESET" (ON) position (Figs. 2-4, pgs. 5-7).
8. Green LED will illuminate when the unit is powered.
9. Upon completion of the wiring, secure enclosure door with screws (supplied).
Caution: Equipment to be installed / serviced by authorized / trained personnel only.
Shut branch circuit power before installing / servicing equipment.
WARNING: To reduce the risk of fire or electric shock, do not expose the unit to rain or moisture.
This installation should be made by qualified service personnel and should conform to the National
Electrical Code and all local codes.
