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 position labeled LINE.
2. Connect the load wiring to the output terminal block
position labeled LOAD.
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.

Two Pole Relay Card Notes
1. Two Pole Relay ratings are 208/240/480 volt, 20 amp
maximum.
2. Relay terminal blocks have a maximum limit of 6 AWG
wire.
3. Two Pole Relays take up two relay slots in the
enclosure.
4. Two Pole Relays come in a Normally Open
configuration.
Two Pole Relay Card Wiring
1. Connect one de-energized branch circuit breaker to one
of the relay terminal block LINE locations.
2. Connect the load side to the output terminal block
position of this same terminal block, labeled LOAD.
3. Connect the other de-energized branch circuit breaker
to the other relay terminal block LINE location.
4. Connect the second load wire to the second terminal
block, labeled LOAD.
5. Tighten down relay terminal screws. Manufacturer’s
recommended torque rating is 18 lbs-in. (1.475 foot-lbs)
(2.0 Nm).
6. Document relay to circuit information for future
reference.
