Important: The conformity of the drive and filter to any standard
does not assure that the entire installation conforms. Other factors can
influence the total installation and only direct measure can verify total
conformity.
Installing an RFI Filter
To install the RFI filter, follow the instructions provided with the
filter. In addition, you should note the following information:
•
Connect the RFI filter between the incoming AC supply line and
the drive power input terminals.
•
Install the filter on the same mounting plate as the drive, if
possible. The filter should be physically close to the drive with
short connections.
Important: To assure that the RFI filter is effective, you must shield
or armor the motor cable and follow the guidelines given in this
manual.
RFI Filter Leakage Current
The optional RFI filter may cause ground leakage currents. Therefore,
you must provide an appropriate ground connection (refer to the
grounding instruction on page 2-14).
!
ATTENTION: To guard against possible equipment
damage, you can only use RFI filters with AC supplies
that are nominally balanced with respect to ground. In
some countries, three-phase supplies are occasionally
connected in a 3-wire configuration with one phase
grounded (Grounded Delta). The filter must not be used
in Ground Delta supplies.
