General Information
The ControlKeeper-2
®
is shipped in one package and is
configured with a 120V transformer or a 277V transformer.
The two relays are mounted in the high voltage compart
-
ment. The logic board and inputs are located in the low volt
-
age compartment. The following information describes the
ControlKeeper-2
®
installation. For programming information,
refer to the Keeper Enterprise Software Manual.
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 service must be performed by qualified
personnel or service technicians.
5. Install in accordance with National Electrical Code and
any other codes that may apply.
6. High Voltage is present inside the lighting 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.
7. Document all wiring that is terminated to the relays so that
the lighting control equipment can be properly configured
and programmed for operation.
8. It is recommended that all low voltage wiring be done with
power removed to the logic board to protect components
from potential shorts during the wiring process.
Mounting the Enclosure
1. Choose a dry location convenient to the circuits being
controlled.
2. Mount the panel on a firm surface using predrilled holes.
3. Connect the enclosure to the circuit breaker panel using
conduit into the punch holes provided.
4. Remove all cuttings and dirt.
Note:
Make certain that high voltage and low voltage
wiring enters the enclosure separately. High Voltage wir-
ing should be brought into the right section of the enclo-
sure. Low Voltage wire should enter in the low voltage
wiring compartment on the left side of the enclosure.
Failure to separate high voltage from low voltage wiring may
cause interference with logic board function.
Wiring the Transformer
The ControlKeeper-2
®
is factory configured with a 120V tran-
former or a 277V transformer. The transformer voltages are
color-coded. The 120V transformer has the power wired to
the black wire and the 277V transformer has the power wired
to the orange wire. The neutral is the white wire.
Connect wires to the transformer. You must provide a dedi
-
cated circuit with circuit protection for the transformer.
Connecting Relay Loads
Relay Notes:
1. The standard relay is rated for single-pole load use only.
Connection of 2 pole circuits/loads to the relay 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.
3. Relay terminal blocks have a maximum limit of 10AWG
wire.
