CONTACTOR
The contactor on the 1-phase 115V model uses a 115V coil (controller option only).
The contactor on the 1-phase 230V model uses a 230V coil (controller option only).
The contactor on the 3-phase model uses a 230V coil (controller option only).
PHASE MONITOR (N360X46GXXX ONLY)
This product is equipped with Phase/Voltage Protection. Please verify correct phasing and voltage before
operating. Note the fans may still operate if phasing is incorrect, but the compressor will not, so the unit
will not cool. Illuminated light on Phase Monitor indicates phase is correct. The phase monitor light can be
seen through a small opening on the back of the unit, above the air intake.
If the light is not illuminated, disconnect power from the unit and swap any two power leads at the
terminal block. This should correct the phasing. The light should now illuminate when power is reapplied.
460 V TO 230 V TRANSFORMER (N360X46GXXX ONLY)
The 230 V from this transformer powers the fans, contactor and optional transformers. 460 V is only used
to run the compressor.
115/230 V TO 10 V TRANSFORMER (OPTIONAL)
This transformer powers the temperature display only.
115/230 V TO 24 V TRANSFORMER AND RELAY (OPTIONAL)
The transformer and relay are used to operate the condenser blower and compressor by using a customer
supplied, remote mounted door switch. This is not a safety door switch, but rather, only helps to reduce
condensation at the evaporator coil if the door is opened. The unit will remain electried when the door
switch is operated with the evaporator fan continuing to operate, and potentially, if temperatures are low
enough, the heater may continue to operate on outdoor models.
