Installing an AC input reactor
An AC input reactor is installed to eliminate the harmonics of the input current. As an
optional device, the reactor can be installed externally to meet strict requirements of
an application environment for harmonics.
The following figure shows the connection of the AC input reactor.

Installing an EMC filter
Note
● The connecting cable between the filter and the controller must be as short as
possible (should be less than 30 cm).
● Ensure that the filter and controller are connected to the same grounding
reference plane, and ensure that the filter is reliably grounded, otherwise the
filtering effect of the filter cannot be achieved.
Use CE‑compliant filters that comply with the emission requirements in Category C2
of EN 61800‑3 and EN 12015. Properly ground the filter. Keep the cable connecting the
filter to the controller shorter than 30 cm.
The following figure shows the connection of the EMC filter.
