Line Reactor/Isolation Transformer

If no isolation transformer is used, we recommend that you always use the specified line reactor with the drive to provide a known supply
impedance for effective operation of the thyristor transient suppression circuits. At least 2% line impedance should be provided in the supply side of
the drive.
Note: On installations requiring compliance with EN61800-3 Table 11, you must fit capacitors between the phase and ground, before the specified
Line Reactor. This applies to DRVs with an armature current <100A.
