Planning the electrical
installation
What this chapter contains
The chapter contains the instructions that you must follow 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 Electric power network specification on page 348.
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.
