Identify cords coming from motor
Control Wiring Instructions:
• For dry contact ON/OFF control, connect dry contact from STOP/
RUN to signal ground.
- Closed contact is motor ON, open contact is motor OFF.
- Connect STOP/RUN wire to signal ground wire if dry contact
ON/OFF control is not used.
• Use the two 4-20ma IN wires for analog current speed control.
- Leave 4-20ma wires disconnected if not used, (less than
5.6ma is OFF).
• 0-10V in to signal ground for analog voltage speed control,
(less than 1V is OFF).
- Connect 10V OUT wire to 10V IN wire for no speed control,
(full speed).
• Use four conductor 26AWG (or heavier), shielded, dual twisted
pair, signal wire with drain wire from J&D control to Permanent
Magnet fan.
• Use the two 4-20ma IN wires for analog current speed control.
- Leave 4-20ma wires disconnected if not used, (less than 5.6ma is OFF).

Maintenance Instructions:
• Disconnect power before cleaning or maintaining your fan in order
to prevent serious injury or death.
• Service and repair of fan should only be completed by a qualified
technician.
• For maximum efficiency and fan life, keep the following free from
dirt and dust: blades, damper doors, motor and guard.
• The totally enclosed air over motor has sealed ball bearings and
does not require additional oil.
General Wiring Instructions:
• Wiring should only be performed by a trained electrician to prevent
injury or death.
• Install manual disconnect switch inside building adjacent to fan.
• Route wire to motor with drip loop and secure. Drip loop will drain
accumulated moisture away from the motor.
• Configure internal wires to match supply voltage and wire accord-
ing to motor nameplate. Test to verify correct rotation.
• Only permit power to unit when guards are properly installed to
prevent injury.
