NOTE
In motors without phase insulation paper or other
insulation reinforcement suitable for operation with
voltage supply (such as a frequency converter), fit a Sine-
wave filter on the output of the frequency converter.
Cable entry holes
The suggested use of the holes are purely recommen-
dations and other solutions are possible. Unused cable
entry holes can be sealed with rubber grommets (for IP21).
