Appendix C – IEC Installation
C-10 ACx=ACS/ACC/ACP ACS/ACC/ACP 604/607 Drives
1. There is double or reinforced insulation between the thermistor and
live parts of the motor.
2. Circuits connected to all digital and analogue inputs of the ACx 600
are protected against contact, and
insulated with basic insulation (the same voltage level as the
converter main circuit) from other low voltage circuits.
3. An external thermistor relay is used. The insulation of the relay must
be rated for the same voltage level as the converter main circuit.
