Wiring the Transformer
The transformer provides power to the Relay Stack
Controller (RSC) and to the ControlKeeper T logic board. The
transformer is multi-tapped and voltages are color coded.
The transformer is available in 120V, 277V, 347V 60 Hz or
220V, 230V, 240V 50/60 Hz models. It is recommended that
a dedicated branch circuit with circuit protection be provided
for the transformer.
1. Connect the solid black wire to the dedicated branch
circuit that is powering the transformer.
2. Connect neutral wire to the wire with the appropriate
color coding for the voltage being used.
See chart below for clarification.

Connecting Relay Loads
The relay cards will be pre-mounted by the manufacturer
in the enclosure per the order specifications.There are
currently three available relay types for the ControlKeeper
T enclosure. This includes the Serial Standard Relay Card,
the Serial Two Pole Relay Card and the Serial Latching 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
once the wire cuttings are removed from the enclosure.
3. Test branch circuits for short circuits prior to landing
wiring on relays.
Note: N
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.
Standard relays are available in a Normally Open
configuration.
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
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 7 lbs-in. (0.59 lbs-foot)
(0.8 Nm).
4. Document relay to circuit information for future
reference.
