Basic devices in the power range 0.37 ... 11 kW
Motor connection
Motor with PTC thermistor or thermal contact (NC contact)
Wire T1, T2 only if the motor is equipped with a PTC thermistor or thermal contact
(NC contact).
An "open" cable acts like an antenna and can cause faults at the drive controller.
