2. Set main switch to the OFF position on all models, (Figs. 1-4, pgs. 4-5).
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 Blue and Brown flying lead of the transformer(s) (Figs. 1-4, pgs. 4-5).
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 (Fig.4, pg. 5)
or terminals marked [1P - 1N through 8P - 8N] on PD8/PD8CB board (Figs. 1-3, pgs. 4-5), carefully
observing polarity.
7. Set main switch on all models to the “RESET” (ON) position (Figs. 1-4, pgs. 4-5).
8. Green LED will illuminate when unit is powered.
9. Upon completion of wiring, secure enclosure door with screws (supplied).
