Implementing A Motor Temperature Sensor Connection - ABB ACS580-01 Hardware Manual

Implementing a motor temperature sensor connection

WARNING! IEC 60664 requires double or reinforced insulation between live
parts and the surface of accessible parts of electrical equipment which are
either non-conductive or conductive but not connected to the protective earth..
To connect a motor temperature sensor and other similar components to the drive,
you have four alternatives:
1. If there is double or reinforced insulation between the sensor and the live parts
of the motor, you can connect the sensor directly to the inputs of the drive.
2. If there is basic insulation between the sensor and the live parts of the motor,
you can connect the sensor to the inputs of the drive if all circuits connected to
the drive's digital and analog inputs (typically extra-low voltage circuits) are
protected against contact and insulated with basic insulation from other low-
voltage circuits. The insulation must be rated for the same voltage level as the
drive main circuit. Note that extra-low voltage circuits (such as 24 V DC) typically
do not meet these requirements.
3. You can connect the sensor to an extension module with reinforced insulation
(eg, CMOD-02) between the sensor connector and the other connectors of the
module. See the table below for the sensor insulation requirement. For sensor
connection to the extension module, see its manual.
4. You can connect a sensor to an external thermistor relay the insulation of which
is rated for the main circuit voltage of the drive.
