Contents of this chapter
This chapter contains the instructions to plan the electrical installation of the drive, for
example, to check the compatibility of the motor and drive, and select the cables,
protections as well as cable routing.
Make sure that the installation is designed and done according to the applicable local
laws and regulations. ABB does not assume any liability whatsoever for any
installation which breaches the local laws and/or other regulations. If the
recommendations given by ABB are not followed, the drive may experience problems
that the warranty does not cover.

Install a hand-operated input disconnecting device between the AC power source
and the drive. You must be able to lock the disconnecting device to the open position
for installation and maintenance work.
