Electrical Connections
Before electrical connections are made, the supply
voltage, phase and ampere capacity must be checked
for compatibility with the fan motor. In addition, the
supply wiring must be properly fused and conform
to local and national electrical codes. If the unit is
supplied with a safety disconnect switch, ensure
proper wiring to the fan motor. Be sure the disconnect
is switched to the “OFF” position before connecting
supply wires. If no disconnect is supplied, ensure the
supply wire is not live before connection. Supply wires
are then connected to the optional safety disconnect
switch (if supplied) or motor.
