• Prevent noise leakage by wrapping cables using shield covers, shield tubes and flexible conduits etc. if noise leaks through
the cable outlet.
• Use an electromagnetic shield gasket and block up the gap between the control panel cabinet and its cover, if noise leaks
through it.
• Connecting the internal panel plate and the cover of the control panel to the main cabinet using an earth strap may be
effective to strengthen the grounding.
• Electromagnetically shielded control panel cabinet is effective for shielding.
• Points of cautions applicable when installing the R7C Series

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.
