8.4 Operation with FI circuit breakers
With SK 200E frequency inverters, leakage currents > 30mA can be expected. If possible, an FI circuit
breaker for the protection of personnel should not be used.
If the frequency inverter is to be used with an FI circuit breaker for the protection of personnel, the leakage
currents to earth must be reduced. For further details, please refer to Section 2.6.4 – 2.6.5. However, due to
the measure “Operation on IT network” the FI loses its specified degree of interference suppression.
8.5 Maintenance and servicing information
In normal use, NORDAC SK 200E frequency inverters are maintenance free. Please note the "general data"
in Section 7.1.
If the frequency converter is being used in a dusty environment, then the cooling-vane surfaces should be
regularly cleaned with compressed air. If air intake filters have been built into the control cabinet, then these
should also be regularly cleaned or replaced.
If you contact our technical support, please have the precise device type (rating plate/display), accessories
and/or options, the software version used (P707) and the series number (rating plate) at hand.
