Planning electrical installation
What this chapter contains
The chapter contains the instructions that you must follow when selecting the motor,
cables, protections, cable routing and way of operation for the drive. If the
recommendations given by ABB are not followed, the drive may experience
problems that the warranty does not cover.
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.
Motor selection
Select the 3-phase AC induction motor according to the rating table on page 113 in
chapter Technical data. The table lists the typical motor power for each drive type.
AC power line connection
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.
Supply disconnecting device
Install a hand-operated input 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.
• Europe: 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.
