General Information
Power Supply Wiring
The ControlKeeper 4A contains a multi-tapped transformer
that is available in 120V/277V/347V 60 Hz or 230V/240V 50
Hz models. Voltages are color coded. 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: See
Transformer Color Chart on page 2 for Neutral
Connections by voltage.
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 three available relay types for the
ControlKeeper 4A 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 the 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.

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)
(0.8Nm).
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 8 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.
