Connection of a motor temperature sensor to the drive I/O
WARNING
IEC 60664 requires double or reinforced insulation between live parts and the surface of
accessible parts of electrical equipment which are either nonconductive or conductive but
not connected to the protective earth.
To fulfill this requirement, the connection of a thermistor (or other similar components) to
the inputs of the drive can be implemented by 3 alternate ways:
- There is double or reinforced insulation between the thermistor and live parts of
the motor.
- Circuits connected to all digital and analogue inputs of the drive are protected
against contact and insulated with basic insulation (the same voltage level as the
drive main circuit) from other low voltage circuits.
- An external thermistor relay is used. Rate the insulation of the relay for the same
voltage level as the main circuit of the drive.
