Power Wiring Installation
DANGER
Always disconnect, lock and tag power source before
installing or servicing. Failure to disconnect power
source can result in fire, shock or serious injury.
IMPORTANT:
Do not connect power until mechanical
installation, fire alarm relay installation, communication
wiring and fan control installation are complete.
IMPORTANT:
Do not apply power to the fan above
the rated voltage of the variable frequency drive (VFD).
Failure to comply with this warning will result in voiding
of the product warranty and may result in permanent
damage to the VFD and motor.
IMPORTANT:
To prevent electrical failures, source
power must comply with the following power quality
requirements. If source power falls outside of these
specified tolerances, an external power line filter will be
required (by others). If other power quality issues are
present, contact the factory for support.

Disconnect and Fuse Installation
1. If provided, mount and wire the optional safety
disconnect switch outside of the sweep of the fan’s
airfoil blades. Installation should be completed per
the disconnect manufacturer’s recommendation.
Be sure to follow all national and local codes for
electrical installation.
2. If fusing is required, refer to the fuse sizing chart.
If the fan was supplied with the optional fused
disconnect, the fuses received will match the
models shown. Install fuses per the manufacturer’s
recommendation. Be sure to follow all national and
local codes for electrical installation.

Pre-Start-Up Checks
1. Disconnect and lock-out all power switches to fan.
2. Check all fasteners on the ceiling mount, mounting
kit, blades, VFD, motor and accessories for
tightness.
3. Rotate the fan impeller by hand to ensure that it
rotates freely and does not come into contact with
any obstructions.
4. Check all electrical connections for proper
attachment.
