WARNING: For safety reasons, when using a phase rotation meter, the phase
rotation must be measured at the upstream protection level and not in the
filter panel itself.
When checking the phase rotation with a phase rotation meter, ensure that the
auxiliary fuse box is open during the measurement process.
WARNING: In a multi-unit filter arrangement, care must be taken to connect all
units to the power supply in an identical way as the master unit (individual
phases and phase rotation). Otherwise, the equipment may be damaged upon
energization and/or may function incorrectly.
Before going to the next step, it is recommended at this stage to first install the other
I/O cabling if required.
Once all the hardware has been cabled,
−
Close the auxiliary circuit fuse box
−
Refit the filter protective cover including PQF-Manager and its connections
−
Close the filter upstream protection
When the power is applied to the active filter:
- The active filter fans will start running
- The DC capacitors will be charged
- The PQF-Manager will initialize and show the 'Welcome' screen (Cf.
or will show a screen indicating that it is in slave mode
If the voltage level or phase rotation is incorrect, the installation should be corrected
before applying power to the filter to avoid potential filter malfunctioning and/or
damage.

Step 4: Basic commissioning parameters set up (using PQF-
Manager)
In order to set up the basic commissioning parameters with the PQF-Manager, navigate
to [/Welcome/Settings/Commissioning] (Cf.
menus of the PQF-Manager is given in
The complete commissioning must be done at the first installation of a filter system and
each time a filter unit is added to an existing filter system.
If the window or some of its items are locked (i.e. a small
present on the screen), the hardware and/or software lock has been engaged. Refer to
Section 7.6
for more information on these features and for guidelines on how to unlock
the filter setting menus.
Note: In active filter systems consisting of more than one master, the PQF-Manager of
the master that has the control over the system has full functionality and the PQF-
