Installation Instructions:
1. Mount unit in the desired location.
2. Set power switch on power distribution board marked [PD] to OFF position for models ALTV2416ULX3 or
ALTV2416ULCBX3
(Figs. 1, 2, pgs. 4, 5). Set power disconnect circuit breaker to OFF position for all
other models (Figs. 3a - 8a, 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: ALTV2416ULCBX3 set for 28VAC operation is not Class 2 Rated, not power-limited.
4. Plug-in 3-wire line cord (Figs. 1, 2, pgs. 4, 5).
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 ALTV2416ULX3 or
ALTV2416ULCBX3
(Figs. 1, 2, pgs. 4, 5). Set power disconnect circuit breaker to RESET (ON) position for
all other models (Figs. 3a - 8a, pgs. 6 - 10).
6. Measure output voltage before connecting devices. This helps avoiding potential damage.
Terminals marked [1P - 16P] 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 ALTV2416ULX3 or
ALTV2416ULCBX3
(Figs. 1, 2, pgs. 4, 5). Set power disconnect circuit breaker to OFF position for all
other models (Figs. 3a-8a, pgs. 6-10).
8. Connect devices to the terminals marked [1P - 1N] through [8P - 8N] on PD8 board (Figs. 1 - 4, 7, 8, pgs. 4 - 7, 9, 10),
or terminals marked [1P - 1N] through [16P - 16N] on PD16W/PD16WCB board (Fig. 5, pg. 8), carefully
observing polarity.
9. Set power switch on power distribution board marked [PD] to ON position for models ALTV2416ULX3 or
ALTV2416ULCBX3
(Figs. 1, 2, pgs. 4, 5). Set power disconnect circuit breaker to RESET (ON) position for
all other models (Figs. 3a - 8a, pgs. 6 - 10).
10. Green LED will illuminate when power is present.
11. Upon completion of the 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.
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 all local codes and
in accordance with the National Electrical Code. Use 75ºC or higher rated UL insulated wiring for con-
necting the unit to the mains. Replace fuses only with the same type and rating (refer to Sixteen (16) Output
