5. Filter installation
Please follow the simple steps below to ensure a safe and reliable filter function. Please always follow
the general safety and installation guidelines provided within this document as well as relevant local,
national or international standards that are applicable. Please note that the following installation steps
are applicable for both IP 00 and IP 20 enclosure.
Step 1: Visual inspection
All Schaffner LCL filters have undergone rigorous testing before they left our ISO 9001:2015 certified
factories. They are packed 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 visible
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.
Step 2: Mounting
LCL filters are best installed as close as possible to the AFE or AIC. Ideally they are mounted next to the
rectifier or motor drive inside the electrical cabinet providing an appropriate protection. Ensure that only
qualified and trained personell has access to the equipement.
All LCL filters FN 6840 are designed for wall-mounting installation.
Important:
In order to ensure sufficient air flow, keep a clearance
of min.150mm above and below the filter to walls or
other components.
Additional work to access the device, caused by not
respected clearance distances, will be accounted
separately.
It must be ensured that the environmental temperature
is kept below 50°C with appropriate thermal
management (e.g. cabinet cooling). Filter operation in
environments with higher temperatures require a
current derating.
