3.6.18 Motor Insulation

For motor cable lengths ≤ than the maximum cable length listed in the
General Specifications tables, the following motor insulation ratings are
recommended because the peak voltage can be up to twice the DC link
voltage, 2.8 times the AC line voltage due to transmission line effects in
the motor cable. If a motor has lower insulation rating, it is recommended
to use a du/dt or sine-wave filter.
