￭ European Union and United Kingdom
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.
￭ North America
Installations must be compliant with NFPA 70 (NEC)
1)
and/or Canadian Electrical Code
(CE) along with state and local codes for your location and application.
1)
National Fire Protection Association 70 (National Electric Code).
￭ Other regions
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.
• Consider the application life time requirements.

Examining the compatibility of the motor and drive
Use asynchronous AC induction motors, permanent magnet synchronous motors 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 Requirements
tables (page 75). For basics of protecting the motor insulation and bearings in drive
systems, see Protecting the motor insulation and bearings (page 75).
