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 enclo-
sure.
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.
Note:
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 equip-
ment.
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.
Note:
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 recom-
mended 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 6 AWG
wire.
Latching Relay Card Wiring
The latching relay is a simple closure, breaking the line
and load wires of a normal circuit. To wire the relay into the
control circuit:
1. Connect a 120, 277 or 347 volt, 20 amp maximum,
de-energized branch circuit breaker to the relay terminal
block.
2. Connect the load wiring to the output terminal block.
Note:
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 18 lb-in. (1.475 foot-lbs)
(2.0 Nm).
4. Document relay to circuit information for future reference.

Modular Relay Card Notes
The Modular Relay Card provides flexible options for relay
control. It is designed to allow modular relay control by allow-
ing you to install a variety of relay module types on the same
relay card. Current available relay module types include a
Two Pole Relay Module (TPRM) Normally Open, the Latching
Relay Module (LRM) and the Standard Relay Module (SRM).
