RFI suppression filter, category C1 (class B)

Use an RFI suppression filter, category C1 (class B), in the inverters if necessary. For more
detailed information, refer to section "EMC" (Page 75).
From the unit designation you can identify whether you have a unit with the option RFI
suppression filter category C1 (class B). In this case, the rating plate is stamped as follows
".2...-.....-....B....".
Refer to section "Type designations" (Page 31) for more detailed information.
The dimensions are unchanged for compact devices. The dimensions of cabinet units
increase if an RFI suppression filter category C1 (class B) is installed. Additional data is
provided in the unit documentation.

Sine-wave filter

Note the following information for the operation of a sine-wave filter
A sine-wave filter is available as an option for the motor power supply.
It must be noted that sine-wave filters are only designed for the nominal clock frequency.
Therefore the parameter "f-pulse min" under "P-INVERTER DATA" must always be set to the
nominal clock frequency.
NOTICE
Overheating of the sine-wave filter
If the clock frequency drops to below the nominal clock frequency of the sine-wave filter,
the filter can overheat. The equipment will be damaged as a result.
For this reason, the parameter "f-pulse min" under "P-INVERTER DATA" must always be
set to the nominal clock frequency.
3.3.13

Additional mains power protection chokes

You can expand a inverter with an additional mains power protection choke. Use an
additional choke if the input side mains power shows a large unbalanced load due to
different voltage on L1, L2 and L3 or if the mains power or if the mains power already has
harmonics. In this case, please contact the Service Center.
