Installation Instructions:
1.
Mount unit in desired location.
2.
Slide switch on PD board to OFF position for models ALTV248 and ALTV248CB
T
urn OFF main switch on all other models,
(F
igs. 3-5, pgs. 5-6).
(F
igs. 1 & 2, pg. 4)
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. 1-5, pgs. 4-6).
Use 18 AWG or larger for all power connections.
5. Measure output voltage before connecting devices. This helps avoid 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 4P - 4N] on PD4/PD4CB board (Figs. 2 & 5, pgs. 4 & 6)
or terminals marked [1P - 1N through 8P - 8N] on PD8/PD8CB board (Figs. 1 & 3, pgs. 4-5), carefully
observing polarity.
7. Slide switch on PD board to ON position for models ALTV248 and ALTV248CB
Turn main switch on all other models to the “RESET” (ON) position
(Figs. 3-5, pgs. 5-6).
(Figs. 1 & 2, pg. 4).
8. Green LED will illuminate when unit is powered.
9. Upon completion of 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 all local codes
and in accordance with the National Electrical Code.
