Installation Requirements for Options

● The LINE terminal of the EMC filter must be connected to the power grid, and the
LOAD terminal must be connected to the AC drive.
5.5 Simple Filter
When no standard EMC filter is installed, a simple filter (capacitor box) can also be
used to suppress the RF electromagnetic noise generated from the power grid and
the AC drive during operation. The simple filter must be grounded securely and the
cable between the filter and AC drive must be shorter than 30 cm.
Figure 5‑1 Installation of the simple filter
5.6 Magnetic Ring and Buckle
The magnetic ring can be used on the input side or output side of the AC drive. Install
it as close to the AC drive as possible. When it is installed on the input side, the noise
in the input power supply system of the AC drive can be suppressed. When it is
installed on the output side, the interference generated by the AC drive to external
devices can be suppressed and the bearing current can be lowered.
