Getting Started

1. Do not discard these installation instructions. Please keep
for future reference and operation information.
2. Always disconnect all power before wiring.
3. Use only as intended and at the listed voltage.
4. All installation and service must be performed by qualified
personnel or service technicians.
5. Install in accordance with the National Electrical Code and
any other codes which may apply.
6. Installation and wiring information contained in this docu-
ment is based on industry-accepted standards and prac-
tices. If conflicts exist between these instructions and any
applicable codes or ordinances, please contact Greengate

7. High Voltage is present inside the enclosure. Use extreme
caution when performing maintenance on this equipment.
Failure to follow this warning and proper safety procedures
could result in severe injury or death, and/or damage to
the equipment.
8. Document all wiring and device terminations and loca-
tions so that devices can be properly configured and
programmed for operation.

Mounting the Cabinet

1. Choose a dry location on a firm surface convenient to the
circuits being controlled. Allow full clearance for the door
of the enclosure to open fully.

Power Supply Wiring

The ControlKeeper-4 is factory configured with either a 120V
or a 277V transformer. Transformer voltages are color coded.
It is recommended that a dedicated branch circuit with circuit
protection be used for power supply wiring.
1. Connect neutral wire to the white wire.
2. If the transformer is a 277V model, connect orange wire to
a 277V circuit. If the transformer is a 120V model, connect
black wire to a 120V circuit.

Connecting Relay Loads

1. Test branch circuits for short circuits prior to connecting and
energizing the ControlKeeper-4.
2. Relay terminal blocks have a maximum limit of 10 AWG wire.
3. Relays are rated for single-pole circuit use. Connection of 2
pole circuits/loads to the ControlKeeper-4 will void the
equipment warranty.
4. Connect a 120 or 277 volt, 20 amp maximum, de-en-
ergized branch circuit breaker to the relay terminal block
position labeled LINE.
