installation
What this chapter contains
This chapter contains instructions for planning the electrical installation of the drive.
Some instructions are mandatory to follow in every installation, others provide useful
information that only concerns certain applications.
Limitation of liability
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.
Selecting the supply disconnecting device
Install a hand-operated input disconnecting device 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.
