and a thermistor protection circuit
are installed.)

￭ Connection of motor temperature sensor to the drive via a relay
PTC alternative A: This table shows the insulation requirement for a customer’s external
relay, and the insulation requirement for the sensor to fulfill decisive voltage class A (double
insulation) of IEC 60800-5-1. The table also shows the insulation of the factory-installed
relay (plus code option for a cabinet-installed drive), and the insulation requirement for the
sensor.
