Wiring the Transformer
Wiring the Transformer
The LiteKeeper 4® is factory configured with a 120V
transformer 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
dedicated circuit with circuit protection for the transformer.
Earth ground must be connected to the stud labeled "GND" ,
located in the high voltage compartment.
Neutral = White

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.
Relay Wiring

Neutrals terminate within the adjoining lighting panel.
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.
Verify that all wire cuttings are removed from the
enclosure.
2.
Take the protective shrink-wrap off of the relay cards
AFTER the wire cuttings are removed from the
enclosure.

3.
Test branch circuits for short circuits prior to landing
wiring on relays.
4.
Connect a 120 or 277 volt, 20 amp max, de-energized
branch circuit breaker to the relay terminal block.
5.
Connect the load wiring to the output terminal block.
Terminal blocks are not polarity sensitive although it

is recommended that line and load be brought into
terminal blocks in the same manner for consistency.
6.
Tighten down relay terminal screws. Manufacturer's
recommended torque rating is 7 lbs-in. (0.59 lbs-foot)
(0.8 Nm).

Document relay to circuit information for future
reference.
Relay Rating: 20 Amps
Wire: 10AWG Max.
LiteKeeper 4 Relay Wiring
Connecting Low Voltage Inputs
The LiteKeeper 4® logic board can support up to 4 dry
contact closure switch inputs. Regardless of input type
used, it is recommended that all input wiring be done prior
to applying power Regardless of input type, the following
notes apply.
1.
All low voltage wiring is Class 2 wiring.
2.
All low voltage wiring must enter the cabinet into the
low voltage section of the enclosure. Low voltage
wiring can be brought into the enclosure from the left
side of the enclosure. Failure to separate high voltage
from low voltage wiring may cause interference with
logic board function.
3.
All low voltage wiring must be run in separate conduit
from line voltage wiring.
4.
Test all low voltage wiring for shorts to AC ground
before connection to the relay panel.
