76 Guidelines for planning the electrical installation

North America

￭
Installations must be compliant with NFPA 70 (NEC)
(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, 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
tables (page 77). For basics of protecting the motor insulation and bearings in drive
systems, see Protecting the motor insulation and bearings (page
Note:
• Consult the motor manufacturer before using a motor with nominal voltage that
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 to the drive output voltage.
