5 Filter installation
Please follow the simple steps below to ensure a safe and reliable filter function for many years.
Please do also always follow the general safety and installation guidelines provided within this docu-
ment as well as relevant local, national or international standards that are applicable. Please note that
the following installation steps are applicable for sine wave filter FN5420 series IP00 and IP20 as well
as dv/dt reator RWK5420 series.
5.1 Step 1: Visual inspection
All Schaffner output filters have undergone rigorous testing before they left our ISO 9001:2008 certified
factories. They are packaged with great care in a sturdy container for international shipment.
However, carefully inspect the shipping container for damage that may have occurred in transit. Then
unpack the filter and carefully inspect for any signs of damage. Keep the shipping container for future
transportation of the filter.
In the case of damage, please file a claim with the freight forwarder involved immediately and contact
your local Schaffner partner for support. Under no circumstances install and energize a filter with visi-
ble transportation damage.
If the filter is not going to be put in service upon receipt, store within the original container in a clean,
dry location, free of dust and chemicals and with respect to named temperature limits, see section 3.1
and 3.2.
5.2 Step 2: Mounting
Output filters are best installed as close as possible to the drive. Ideally, they are mounted next to the
inverter or motor drive inside the electrical cabinet or control room. An adequately long cable must
connect the output filter to the motor, in respect with the drive and filter specification.
FN5420 IP 00 and RWK5420 are designed for floor mounting while FN5420 IP20 are designed for wall
mounting. These are the recommanded mounting positions (IP00 only) but different mounting positions
might be permitted.
