R7D-DC8C
EM-7802-U Rev.2 P. 6 / 8
Use (e.g.) a shield cover
when noise leaks through
the opening.
To external apparatus
Keep the opening
for cabling as small as
possible.
Install an electromagnetically
shielded gasket when
noise leaks through
the opening.
Shielding is strengthened
by using an electro-
magnetically shielded
control panel.
By connecting the
internal panel plate
and the panel cover with
an earth strap, grounding
may be strengthened and
EMC may be improved.
Ground the control panel
at low impedance using
(e.g.) braided wires.
Keep the opening for
ventilation as small as
posible.
Attach an electro-
magnetically shielded
filter when noise leaks
through the opening.
Install the R7D Series inside
a control panel.
Attachment part of earth
clamp should be fixed with
screw in conduction with the
internal panel plate.
