Connector PinOuts and Wiring 32
X3: Discrete I/O for Motor Thermals
This 6-pin Phoenix Contact terminal block provides connectivity to low impedance 12 – 24 VDC motor
thermostat overload detection. This is a normally closed contact, in normal mode operation the Geo direct
PWM Drive expects to see 12 – 24 VDC coming into Pins #1 and #3 respectively for motors 1 and 2.
