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.
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
conductor.
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.
