Design Guide | iC7 Series Air-cooled System Modules In an IT system, filter losses in a single phase ground fault depend on the setup. All capacitances to ground should be minimized to minimize the fault current. The fault current increases the losses, and continuous operation during the ground fault cannot be guaranteed, especially if the filter is already in the limits without the fault.

Page 73: Maintenance
Preventive Maintenance Recommendations Generally, all technical equipment, including Danfoss AC drives need a minimum level of preventive maintenance. To ensure trouble-free operation and long life of the drive, regular maintenance is recommended. It is also recommended as a good service practice to record a maintenance log with counter values, date, and time describing the maintenance and service actions.
