Attach an electro-
magnetically shielded
filter when noise leaks
through the opening.
By connecting the
internal panel plate
and the panel cover with
an earth strap, grounding
may be strengthened and
EMC may be improved.
Shielding is strengthened
by using an electro-
magnetically shielded
control panel.

posible.
Ground the control panel
at low impedance using
(e.g.) braided wires.
