High Temperature Installation Typical Installation
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.
The supply wires are then connected to an optional
safety disconnect switch (if ordered) or wired directly
to the motor.
For belt drive units in Emergency Smoke Removal
installations, the electrical supply must be kept out of
the airstream. They may also require an isolated power
supply so that if power is cut to the building in the event
of a fire, the fan will continue to operate. Check the
local and national electrical codes for emergency smoke
removal fans.
