Wiring the Transformer
Failure to separate high voltage from low voltage wiring may
cause interference with logic board function.

Wiring the Transformer
The transformer provides power to the Standard
Override Card (SOC) and to the controller logic board.
The transformer is multi-tapped and voltages are color-
coded. The transformer is available in 120/277 VAC and
120/347 VAC models. It is recommended that a dedicated
branch circuit with circuit protection be provided for the
transformer.
1. Connect neutral wire to the wire with the appropriate
color-coding for the voltage being used: White/
Black=120 VAC, White/Orange=277 VAC,
Brown=347 VAC.
2. Connect the solid black wire to the dedicated branch
circuit that is powering the transformer.

Connecting Relay Loads
The relay cards will be pre-mounted by the manufacturer in
the enclosure per the order specifications.
There are currently four available relay types for the
enclosure. This includes the Standard Relay Card, the
Modular Relay Card, the Latching Relay Card and the Two
Pole Relay Card. Please refer to the specific section for your
relay card type that you are wiring. For all relay types:
1. Verify that all wire cuttings are removed from the
enclosure.
2. Take the protective shrink-wrap off of the relay cards
AFTER the wire cuttings are removed from the
enclosure.
3. Test branch circuits for short circuits prior to landing
wiring on relays.
N ote: Neutrals terminate within the adjoining lighting panel.
Standard Relay Card Notes
1. The Standard Relay Card is rated for single-pole load
use only. Connection of 2 pole circuits/loads to the
Standard Relay Card will void the equipment warranty
and may result in severe injury or death, and/or damage
to the equipment.
2. Relay ratings are 120 or 277 volt, 20 amp maximum.
3. Relay terminal blocks have a maximum limit of 10 AWG
wire.
Standard Relay Card Wiring
The standard relay is a simple contact closure, breaking the
line and load wires of a normal circuit. To wire the relay into
the control circuit:
1. Connect a 120 or 277 volt, 20 amp max, de-energized
branch circuit breaker to the relay terminal block.
2. Connect the load wiring to the output terminal block.
N ote: Terminal blocks are not polarity sensitive although it
is recommended that line and load be brought into
terminal blocks in the same manner for consistency.
3. Tighten down relay terminal screws. Manufacturer's
recommended torque rating is 7 lbs-in. (0.59 lbs-foot)
(0.8Nm).
