74 Electrical installation
Input cable connection procedure
Connect the input cable phase conductors to the drive module terminals U1, V1 and W1
and the PE conductor to the PE terminal. Connect the twisted shield of the input cable to
the PE terminal even if it is not used as the PE conductor.
Removing the protective covering
The protective covering on top of the drive module prevents dust from borings and
grindings from entering the module when installing. The covering is used because
electrically conductive dust inside the unit may cause damage or malfunctioning.
WARNING! Remove the protective covering from the top of the drive module after
the installation. If the covering is not removed, the cooling air cannot flow freely
through the module and the drive will run to overtemperature.
