The disconnecting device must conform to the applicable local safety regulations.
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 devices only: Select contactor with utilization category AC-1 (number of operations
under load) according to IEC 60947-4,
Low-voltage switch gear and control gear.
• Consider the application life time requirements.

Examining the compatibility of the motor and drive
Use asynchronous AC induction motors, permanent magnet synchronous motors, AC
induction servomotors or ABB synchronous reluctance motors (SynRM motors) with the
drive.
Select the motor size and drive type from the rating table on basis of the AC line voltage
and motor load. You can find the rating table in the appropriate hardware manual. You can
also use the DriveSize PC tool.
Make sure that the motor can be used with an AC drive. See
For basics of protecting the motor insulation and bearings in drive systems, see
the motor insulation and bearings (page 76)
Note:
• Consult the motor manufacturer before using a motor whose nominal voltage differs from
the AC line voltage connected to the drive input.
• The voltage peaks at the motor terminals are relative to the supply voltage of the drive,
not the drive output voltage.
■
Protecting the motor insulation and bearings
The drive employs modern IGBT inverter technology. Regardless of frequency, the drive
output comprises pulses of approximately the drive DC bus voltage with a very short rise
