Contents of this chapter

This chapter contains circuit diagram examples. The purpose of the example circuit diagrams
is to help in understanding the operation of the ATEX-certified motor thermal protection
functions. The diagrams do not cover all possible details and variants of the drives. The
component designations do not necessarily match each drive. For the actual configuration,
see the circuit diagrams delivered with the drive.
WARNING!
Do not connect, test or measure a drive based on the diagrams of this manual.
Each delivery is unique. Before you start the work on the electric circuits of a drive,
always refer to the delivery-specific circuit diagrams.
For the sensor connection, ABB recommends to use shielded twisted-pair cable. This type
of cable decreases electromagnetic interference in the sensor circuit.
