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 R7M Series inside

a control panel.

Attachment part of earth

clamp should be fixed with 

screw in conduction with the

internal panel plate.

• Points of cautions applicable when installing the R7M Series
