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.
1. Mount unit in 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. 11, 12).
Secure enclosure to earth ground.
2. Set power switch on power distribution board marked [PD] to OFF position for models ALTV248UL or
ALTV248ULCB (Figs. 1a, 2a, pg. 5). Set power disconnect circuit breaker to OFF position for all
other models (Figs. 3a-10a, pgs. 6-10).
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 wire marked [28V] is connected to the terminal marked [P] and
the wire marked [24V] is connected to the terminal marked [S].
Note: ALTV248ULCB set for 28VAC operation is not Class 2 Rated, not power limited.
4. Connect AC power to the black and white flying leads of the transformer(s) (Figs. 1-10, pgs. 5-10),
secure green lead to earth ground. Use 18 AWG or larger for all power connections.
Keep power limited (PTC protected outputs only) wiring separate from non-power limited wiring.
Minimum 0.25” spacing must be provided. Use separate knockouts.
5. Set power switch on power distribution board marked [PD] to ON position for models ALTV248UL or
ALTV248ULCB (Figs. 1a, 2a, pg. 5). Set power disconnect circuit breaker to RESET (ON) position for
all other models (Figs. 3a-10a, pgs. 6-10).
6. Measure output voltage before connecting devices. This helps avoid potential damage.
Terminals marked [1P - 8P] are of the same polarity.
CAUTION: Determine the maximum operating voltage of the equipment being powered before adjusting
the output voltage.
7. Set power switch on power distribution board marked [PD] to OFF position for models ALTV248UL or
ALTV248ULCB (Figs. 1a, 2a, pg. 5). Set power disconnect circuit breaker to OFF position for all
other models (Figs. 3a-10a, pgs. 6-10).
8. Connect devices to terminals marked [1P - 1N through 4P - 4N] on PD4/PD4CB board (Figs. 9, 10, pgs. 9, 10)
or terminals marked [1P - 1N through 8P - 8N] on PD8/PD8CB board (Figs. 1-8, pgs. 5-8), carefully
observing polarity.
9. Set power switch on power distribution board marked [PD] to ON position for models ALTV248UL or
ALTV248ULCB (Figs. 1a, 2a, pg. 5). Set power disconnect circuit breaker to RESET (ON) position for
all other models (Figs. 3a-10a , pgs. 6-10).
10. Green LED will illuminate when power is present.
11. Upon completion of wiring, secure enclosure door with screws (supplied). Installation of cam lock is optional.
Caution: Equipment to be installed/serviced by authorized/trained personnel only.
Shut branch circuit power before installing/servicing equipment.
