Step 3: Voltage Rating Check/Adaptation And Phase Rotation Check - ABB PQFS Installation, Operation And Maintenance Instructions

Notes:
When a filter consists of more than one unit, attention has to be paid to the proper
termination of the communication bus between the different units. This communication
bus is depicted in the below
units.

In order to terminate the bus correctly, the fourth switch (counting from left to right) from

WARNING: Failing to terminate the communication bus properly will lead to
equipment malfunction and equipment damage.

· Do not use other settings than the ones mentioned in the table
· It is recommended to assign increasing addresses starting from the main master
at the left and moving right
· Assigning the same address to different filter units in one filter system will lead to
the filter not being able to start up and go in error (Bad Ratings)

High: For the first unit in a filter system (single unit filter or first physical unit of a
multi-unit filter)
High: For the last physical unit of a multi-unit filter
Low: For all the other units
· The active filter nominal voltage setting must be adapted to the actual network
voltage by adjusting the power supply connection of the control voltage (Cf.
Figure 18, wire 'N'). Ensure that the filter panel is isolated upstream before
changing the power supply connection of the control voltage.
By default the power supply connection of the control voltage is configured for
networks in the voltage range 380-415 V (Cf.
voltage range 208-240 V, use the connection given in
Note that in addition to configuring the unit hardware for a certain voltage range,
the network voltage also has to be set up in the filter controller software
(commissioning window).
