Planning the electrical installation

What this chapter contains

This 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 in the chapter
Technical
Only one permanent magnet synchronous motor can be connected to the inverter
output. It is recommended to install a safety switch between the permanent magnet
motor and the drive output in order to isolate the motor from the drive during
maintenance work on the drive.

Supply 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

If the drive is used in an application which must meet the European Union Machinery
Directive 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 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)
data. The table lists the typical motor power for each drive type.
