Note!
ƒ Fusing the motor cable is not required.
ƒ The drive controller features 2 connections for motor
temperature monitoring:
– Terminals T1, T2 for connecting a PTC thermistor or thermal
contact (NC contact).
– Pins X8/5 and X8/8 of the incremental encoder input (X8) for
connecting a KTY thermal sensor.

Wire T1, T2 only if the motor is equipped with a PTC thermistor or thermal
contact (NC contact).
ƒ An "open" cable acts like an antenna and can cause faults on the drive
controller.

Danger!
ƒ All control terminals only have basic insulation (single
isolating distance) after connecting a PTC thermistor or a
thermal contact.
ƒ Protection against accidental contact in case of a defective
isolating distance is only guaranteed through external
measures, e.g. double insulation.
