Power Wiring
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.
DANGER
Pour écarter les risques d’incendie, de choc électrique
ou de blessure grave, veiller à toujours débrancher,
verrouiller et étiqueter la source de courant avant
l’installation ou l’entretien.
IMPORTANT:
Do not apply 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.
Allowable Voltage
Fluctuation
+/- 10% of nominal
Allowable Frequency
Fluctuation
+/- 5% of nominal (47-63 Hz)
Area of Use
Do not install fans in electrical environments
with Pollution higher than Degree 2 in
accordance with UL 61800-5-1
Surge Immunity
Do not install fans in electrical environments
above Installation Class 3 in accordance
with IEC 61000-4-5
Hardware/Tools Needed (Not Included):
• Phillips Screwdriver
With Optional Electrical Plug
1. If the fan is supplied with the optional electrical
plug for power wiring, refer to the chart below for

provided by others.
2. Install the receptacle according to all national and
local codes for electrical wiring.
3. Insert the electrical plug into the receptacle and
twist to lock the plug in place.
4. Secure any loose power cable to the building
structure to ensure it does not interfere with fan
performance.
Without Optional Electrical Plug
1. If the fan is not supplied with the optional electrical
plug, refer to the wiring diagrams below to
complete power wiring.
2. Secure any loose power cable to the building
structure to ensure it does not interfere with fan
performance.

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. Fusing is required by code unless otherwise
specified by local authority having jurisdiction
(AHJ). Refer to the fuse sizing chart below
and install fuses per the manufacturer’s
recommendation. If the fan was supplied with the
optional fused disconnect, the fuses received will
match the models shown. Be sure to follow all
national and local codes for electrical installation.
IMPORTANT:
Warranty may be voided at
manufacturer’s discretion if correct fuses are not
installed.
