60IT (ungrounded) systemsIn units with EMC filter options (+E202 and +E200 in the type code), disconnect thefilter capacitors before connecting the drive to an ungrounded system.WARNING! If a drive with EMC filter selection +E202 or +E200 is installed on an ITsystem [an ungrounded power system or a high resistance-grounded (over 30 ohms)power system], the system will be connected to earth potential through the EMCfilter capacitors of the drive. This may cause danger or damage the unit.Disconnecting the EMC filter capacitorsRemove the two screws shown below.View of frame size R5Note concerning units of frame size R5: When the capacitors of EMC filter +E202or +E200 are disconnected, the EMC Directive requirements in second environmentwill not be fulfilled.Note concerning units of frame size R6: When the capacitors of EMC filter +E202are disconnected, the EMC Directive requirements may not be fulfilled in firstenvironment, but are fulfilled in second environment. When the capacitors of EMCfilter +E200 are disconnected, the EMC Directive requirements in secondenvironment are still fulfilled.See chapter Technical data / CE marking.Electrical installation
