Electrical Connection
1. Connect supply wiring to the disconnect switch (non-fused
standard).
2. The motor is factory set at the voltage marked on the fan
nameplate. Check the line voltage with the nameplate voltage.
3. The main power wiring should be sized for the ampacity
shown on the nameplate. Size wires in accordance with the
ampacity tables in Article 310 of the National Electrical Code.
If long wires are required, it may be necessary to increase
wire size to prevent excessive voltage drop. Wires should be
sized for a maximum of 3% voltage drop.
4. Disconnect switches are not fused. The power leads must be protected at the point of distribution in accordance with the fan
nameplate.
5. All units must be electrically grounded in accordance with local codes or, in the absence of local codes, with the latest edition
of the National Electrical Code (ANSI/NFPA 70). A ground lug is provided as standard in the unit terminal box. Size grounding
conductor in accordance with Table 250-95 of the National Electrical Code. DO NOT use the ground lug for connecting a neutral
conductor.
6. Supply voltage to the power ventilator should not vary by more than 10% of the value indicated on the unit nameplate. Phase
unbalance must not exceed 2%.
1. Use copper conductors only.
2. Protect wiring from sharp edges. Leave some slack in the
line to prevent damage. Do not allow the power or speed
control cables to kink or come in contact with oil, grease,
hot surfaces or chemicals. If damaged, discontinue use
immediately and have cord replaced. Use proper strain
relief.
CAUTION
Speed Control Options: ODP & TENV Motors
The following speed control options are
available for the Aerovent EC motor.
Coming standard with the motor is
both a motor mounted dial, for speed
adjustment at the fan and a 0-10V DC
control lead. The 0-10V DC control
lead can be used with a remote speed
control, either field supplied or supplied
by Aerovent. See table to the right for
available control methods and applicable
sections. See Maximum RPM tables on
page 8 for maximum allowable RPM for
fan/motor combinations.
1.
Motor Mounted
Dial, MMD
(Standard Feature)
– A potentiometer
is mounted to the
motor housing
offering full speed
control range. Speed adjustment is
made with a small flat head screwdriver.
With this option, the motor’s 0-10V DC
control leads are terminated in a standard 2x4 junction box from the factory and can remain there if not required by the end user.
2.
0-10V DC Lead (Standard Feature)
– A 36" long control lead is
prewired from the motor, which accepts
a 0-10V DC signal and can be wired into
building control systems or field supplied
controls. With this option, the control
leads are terminated in a standard 2x4
junction box from the factory.

maintenance. Although motor may be off and not
running when a 0-1.9V DC signal is present, high voltage
will still be present at the motor.
