Motor temperature measurement through the standard I/O interface

This section describes the temperature measurement of one motor when the RMIO
drive control board is used as the connection interface.
WARNING! According to IEC 664, the connection of the motor temperature sensor
to the RMIO board requires double or reinforced insulation between motor live parts
and the sensor. Reinforced insulation entails a clearance and creepage distance of
8 mm (400 / 500 V AC equipment). If the assembly does not fulfil the requirement:
• The RMIO board terminals must be protected against contact and they may not
be connected to other equipment.
Or
• The temperature sensor must be isolated from the RMIO board terminals.
