Step 1: Visual and installation check
WARNING: Make sure that the filter supply is isolated during the visual and installation
check. For safety reasons, this should be done upstream of the active filter and before
removing the right protective cover. In multi-unit filters, ensure that all units are
disconnected from the supply.
In order to perform a successful installation and commissioning, only the right side of
the protective cover of the filter needs to be removed.
WARNING: The left side of the protective cover should not be removed because there
are live parts underneath. When the right side of the protective cover is removed, open
the auxiliary power fuse holder. Failure to adhere to these guidelines may result in
lethal electric shock and/or filter damage.
WARNING: Make sure that the filter is installed at a location where no conductive dust
is present. Conductive dust when distributed in the filter panel may lead to equipment
failure.
−
Check that the mechanical and electrical installation fulfils the requirements described
in
Chapter 5
and
Chapter 6
of this manual.
Remove the filter lifting ribbon if it is
still present.
−
Pay attention to the ambient temperature noting the filter cooling requirements.
−
Check visually the condition of the filter (e.g. for transportation damage).
−
Remove the anti-corrosion modules which are affixed at the inside of the filter, at
the bottom (next to the fan and IGBT assembly).
−
Check the tightness of all connections including power cable connections, CT
connections, digital I/O connections on the PQF-Manager and the control board
connections inside the filter.
−
Ensure that the feeding cable protection devices are rated appropriately (see

Step 2: Setting the address of each unit in a multi-unit filter and
terminate the CAN bus
Each filter is defined by a filter address. This address is by default set to 1.
In a multi-filter arrangement, the address of each unit has to be set to a unique value.
Setting two filter units in the same system to the same address will lead to a conflict and
will inhibit the filter from running.
