Selecting The Main Contactor; Checking The Compatibility Of The Motor And Drive - ABB ACS180-04S-03A7-1 Hardware Manual

44 Guidelines for planning the electrical installation
To comply with European Union directives and United Kingdom regulations related
to standard EN 60204-1, the disconnecting device must be one of these types:
• switch-disconnector of utilization category AC-23B (IEC 60947-3)
• disconnector that has an auxiliary contact that in all cases causes switching
devices to break the load circuit before the opening of the main contacts of
the disconnector (EN 60947-3)
• circuit-breaker suitable for isolation in accordance with IEC 60947-2.

Selecting the main contactor

You can equip the drive with a main contactor.
Follow these guidelines when you select a customer-defined main contactor:
• Dimension the contactor according to the nominal voltage and current of the
drive. Also consider the environmental conditions such as surrounding air
temperature.
• IEC installations: Select contactor with utilization category AC-1 (number of
operations under load) according to IEC 60947-4.
• Consider the application life time requirements.

Checking the compatibility of the motor and drive

Use asynchronous AC induction motor, or permanent magnet synchronous motor
with the drive. Multiple induction motors can be connected to the drive at a time
when using the scalar motor control mode.
Make sure that the motor(s) and the drive are compatible according to the rating
table in the technical data.
