2.
If there is basic insulation between the sensor and the live parts of the motor,
or if the insulation type is not known: You can connect the sensor to the drive
via an option module. The sensor and the module must form a double or
reinforced insulation between the motor live parts and the drive control unit.
See
Connecting a motor temperature sensor to the drive through an option
. Make sure that the voltage does not exceed the maximum
allowed voltage over the sensor.
3.
If there is basic insulation between the sensor and the live parts of the motor,
or if the insulation type is not known: You can connect a sensor to a digital
input of the drive via an external relay. The sensor and the relay must form a
double or reinforced insulation between the motor's live parts and the digital
input of the drive. Make sure that the voltage does not exceed the maximum
allowed voltage over the sensor.

Connecting a motor temperature sensor to the drive through an option
module
This table shows:
•
option module types that you can use for the motor temperature sensor
connection
•
insulation or isolation level that each option module forms between its
temperature sensor connector and other connectors
•
temperature sensor types that you can connect to each option module
•
temperature sensor insulation requirement in order to form, together with
the insulation of the option module, a reinforced insulation between the motor
live parts and the drive control unit.
