The degree of protection of an input choke is IP20. Refer to Dimensions (page 210)
for dimensions, wire sizes and tightening torques.
Guidelines for installing an input choke
Obey these guidelines when you install the input choke:
• If an external EMC filter is also installed, connect the input choke between the
supply and the filter.
• For optimal operation of the choke, fasten the drive and the choke on the same
conductive surface.
• Make sure that the choke does not prevent the airflow through the drive
module, and that the hot air rising from the choke cannot enter the air inlet of
the drive module.
• Keep the cable between the drive and the choke as short as possible.
WARNING!
The input choke is hot when in use and for some time after the use.
