Installation
Be sure to use a new neoprene “O” ring to properly seal the rear cover. Discard the used
one.
Stator Connections
You are responsible for supplying the wiring for the motor phase leads and motor ground
connection (4 conductors). This wiring can be either a cable assembly or discrete wires. If a
shielded cable is used, the shield should be terminated at one of the safety ground terminals
on the amplifier’s terminal block.
If discrete wires are used the wires should be twisted or braided together.
Motor Wiring Requirements
High temperature wire suitable for 105°C (221°F) is recommended for motor sizes DX-8200
through DX-8400 regardless of the application.
Each of the DX-316 through DX-6300 NPT model motors has an 80°C thermal switch that is
wired in series with the winding protection circuit in the FX amplifier. This thermal switch
monitors the ambient temperature in the rear of the motor. This allows the motors to be wired
with typical 80°C (176°F) class wire.
Note
The connectorized motors DO NOT have the 80°C switch.
