ALTV2416UL Series - 3 -
2. Set power switch on power distribution board marked [PD] to OFF position for models
ALTV2416ULX or ALTV2416ULCBX (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: ALTV2416ULCBX 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 - 8, pgs. 4 - 10).
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
ALTV2416ULX or ALTV2416ULCBX (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
ALTV2416ULX or ALTV2416ULCBX (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 terminals marked [1P - 1N] through [8P - 8N] on PD8 board (Figs. 1 - 4, pgs. 4-7,
Figs. 7 - 8, pgs. 9 - 10), or terminals marked [1P - 1N] through [16P - 16N] on PD16W/
PD16WCB board (Figs. 5 - 6, pg. 8), carefully observing polarity.
9. Set power switch on power distribution board marked [PD] to ON position for models
ALTV2416ULX or ALTV2416ULCBX (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 the National Electrical
Code and all local codes. Use 75˚C or higher rated UL insulated wiring for connecting the unit to the
mains. Replace fuses with the same type and rating (refer to Sixteen (16) Output ALTV2416UL Reference
Chart, pg. 2).

The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user
to the presence of an insulated DANGEROUS VOLTAGE within the product’s enclosure that may
be of sufficient magnitude to constitute an electric shock.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of
important operating and maintenance (servicing) instructions in the literature accompanying the
appliance.
CAUTION: To reduce the risk of electric shock do not open
enclosure. There are no user serviceable parts inside. Refer servicing
to qualified service personnel.
