ABB ACS880-07 - Connecting a Motor Temperature Sensor to the Drive through an Option Module

￭
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.
