1. Mount unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes
Installation Instructions:
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, pgs. 10-12). Secure enclosure to earth ground.
2. Set power switch on power distribution board marked [PD] to OFF position for models ALTV244UL,
ALTV244ULX or ALTV244ULCB (Figs. 1-3, pgs. 4-6).
- 2 - ALTV244UL Series
3. All units are factory set for 24VAC operation.
For 28VAC operation adjust unit prior to applying power as follows:
Remove wires marked [24V] and [28V] from terminals marked [P] and [S].
Connect wire marked [28V] to terminal marked [P] and connect wire marked [24V] to terminal marked [S].
Note: ALTV244ULCB 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 (Figs. 1-5, pgs. 4-8).
Secure green lead to earth ground. Use 18 AWG or larger gauge 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 ALTV244UL,
ALTV244ULX or ALTV244ULCB (Figs. 1-3, pgs. 4-6).
6. Measure output voltage before connecting devices. This helps avoiding potential damage.
Terminals marked [1P - 4P] 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 ALTV244UL,
ALTV244ULX or ALTV244ULCB (Figs. 1-3, pgs. 4-6).
8. Connect devices to the terminals marked [1P] - [1N] through [4P] - [4N] on PD4 or PD4CB board
(Figs. 1-5, pgs. 4-8), carefully observing polarity.
9. Set power switch on power distribution board marked [PD] to ON position for models ALTV244UL,
ALTV244ULX or ALTV244ULCB (Figs. 1-3, pgs. 4-6).
10. Green LED will illuminate when power is present.
11. Upon completion of the wiring, secure enclosure door with screws (supplied).
Installation of a 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 Four (4) Output ALTV244UL 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.
