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 must be done upstream of the active
filter and before removing the protective cover. In multi-unit filters, ensure that all
units are disconnected from the supply.
In order to perform a successful installation and commissioning, the filter protective cover
must be removed.
WARNING: When the protective cover is removed, open the auxiliary power fuse
holder. Verify that the filter DC capacitors are discharged before touching them.
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.

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.
In a filter system consisting of more than one unit, the filter with the lowest address will be
considered as the first unit in the chain. The filter with the highest address will be
considered as the last unit in the chain:

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 capsules 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 section
and tightness, 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 (Cf.
Table
19)
In master-slave filter arrangements, it is recommended to assign the lowest
address to the master unit and increment the address by 1 for the next slave etc.
In master-master arrangements, the lowest address must be assigned to the
master unit that is considered as the main controlling unit.
