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 data. The table lists the typical motor power for each drive type.
Only one permanent magnet synchronous motor ca
n 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 or DC supply. Alternatively, the drive can
be powered from a suitable fixed DC supply.
WARNING! As the leakage current of the device typically exceeds 3.5 mA, a
fixed installation is required according to EN 61800-5-1.
