The following applies to TT and IT systems:
All elements protected by a common protective device must be connected to the same earthing via
protection earth conductors.
All elements apt to be touched simultaneously must be connected to a common earthing.
The following applies additionally to IT systems:
No active conductor within the installation is permitted to be earthed directly. All elements must be
connected individually, in groups, or in total with a protection earthing conductor.
Single-phase connector system
with protection earth conductor
Do not operate more than 5 EcoDrives on one circuit fused with 16 amps.
Threephase connector system with protection earth conductor
Make sure to distribute loads evenly in a threephase AC system!
Do not operate more than 3 EcoDrives on one face fused with 16 amps in order not to overload
the N-conductor!
The EcoDrive is a protection class I device, i.e. for protection at indirect touching it comprises a
protection earth connection.
The EcoDrive is permitted to operate only in a properly functional protection earth system in
compliance with all local rules and regulations in order to avoid danger to persons by electric
shock or fire hazards in case of malfunction.
