ƒ do not integrate any further cable into the motor cable (e.g. for blowers
etc.).
ƒ shield the supply cable for temperature monitoring of the motor (PTC or
thermostat) and install it separately from the motor cable.
Special conditions allow you to integrate the supply cable for temperature monitoring of
the motor into the motor cable: ( 169)
