WARNING! As the thermistor input on the JCU Control Unit is not insulated
according to IEC 60664, the connection of the motor temperature sensor
requires double or reinforced insulation between motor live parts and the
sensor. If the assembly does not fulfil the requirement,
- the I/O board terminals must be protected against contact and must not be
connected to other equipment
or
- the temperature sensor must be isolated from the I/O terminals.
The figure below shows a motor temperature measurement when thermistor input TH
is used.
