Line connection conditions for the converter with the motor 1FL2
Description
The drive system is designed for connection to grounded TN/TT and non-grounded IT mains
supply networks.
Depending on the motor/converter combination and the planned installation altitude, the
following constraints must be taken into account regarding the line connection.

NOTICE
Damage to motor insulation due to excessive voltages
In the event of a ground fault in the IT supply system, the motor insulation can be damaged by
the higher voltage to ground.
• Use a ground fault monitor.
• Eliminate the ground fault as quickly as possible.
