FIELD POWER WIRING
WARNING: ALL AIR CURTAINS SHOULD BE INSTALLED BY QUALIFIED PERSONNEL.
1.Before wiring be sure that available power supply, voltage, phase and frequency corresponds to that specified on heater rating plate. In addition, make certain that service capacity is sufficient to handle load imposed by the equipment.
2.Install all wiring, protection and grounding in accor- dance with the National Electrical Code (NEC) and all local requirements.
WARNING: THIS FAN HAS AN INTERNAL SELF RESETTING THERMAL OVERLOAD PROTECTOR. ALWAYS DISCONNECT FROM POWER SUPPLY BEFORE SERVICING.
3.Run proper size copper power supply conductors from
the field power supply disconnects, (supplied by others) with insulation rated minimum 75°C (167°F). One set of conductors from 460VAC, 50/60Hz supply source shall be routed through the 3/4 inch conduit knockout, using a suitable knockout connected to the contactor contact terminals marked L1, L2, L3.
4.The heater control box must have an unbroken electrical ground to minimize personal injury if an electrical fault should occur.
FIELD CONTROL WIRING
Electric heater is equipped with a
for 24V control circuit. Thermostat model number RSV-
