Wiring the Transformer
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.
Transformer Wiring Information
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. If a
Modular Relay Card or Two Pole Relay Card is ordered, a
deeper enclosure will be provided to allow for clearance
of the transformer with the larger relay types. 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.

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
10AWG 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.

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) (0.8 Nm).
4. Document relay to circuit information for
future reference.

Latching Relay Card Notes
1. The Latching Relay Card is rated for single-pole load use
only. Connection of 2 pole circuits/loads to the Latching
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 120/277/347 volt, 20 amp maximum.
3. Relay terminal blocks have a maximum limit of
6AWG wire.
