Planning the electrical installation

What this chapter contains

The chapter contains the instructions that you must follow when when checking the
compatibility of the motor and drive, and selecting cables, protections, cable routing
and way of operation for the drive.
Note: The installation must always be designed and made according to applicable
local laws and regulations. ABB does not assume any liability whatsoever for any
installation which breaches the local laws and/or other regulations. Furthermore, if
the recommendations given by ABB are not followed, the drive may experience
problems that the warranty does not cover.

Implementing the AC power line connection

See the requirements in section
Use a fixed connection to the AC power line.
WARNING! As the leakage current of the device typically exceeds 3.5 mA, a fixed
installation is required according to IEC 61800-5-1.

Selecting the supply disconnecting device (disconnecting means)

Install a hand-operated supply disconnecting device (disconnecting means) between
the AC power source and the drive. The disconnecting device must be of a type that
can be locked to the open position for installation and maintenance work.

European union

To meet the European Union Directives, according to standard EN 60204-1, Safety
of Machinery, the disconnecting device must be one of the following types:
• a switch-disconnector of utilization category AC-23B (EN 60947-3)
• a disconnector having 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)
• a circuit breaker suitable for isolation in accordance with EN 60947-2.

Other regions

The disconnecting device must conform to the applicable safety regulations.
