Please check that the mains voltage fits the mains voltage of the frequency con-

verter, which can be seen from the nameplate.

400-Volt units with RFI-filters may not be connected to mains supplies in which the

voltage between phase and earth is more than 300 Volts. Please note that for the

IT mains and the delta earth the mains voltage can exceed 300 Volts between phase

and earth. Units with type code R5 (IT mains) can be connected to mains supplies

with up to 400 V between phase and earth.
