The R7D communicates in the baud rate setting detected at
the startup with the switch set to the positions 0 (125 kbps),
1 (250 kbps) or 2 (500 kbps).
For the settings 3 through 9, it analyzes the PLC’ s network
to determine the baud rate on the network.

CONFORMITY WITH CE MARKING
■ CE MARKING
CE marking requires to integrate safety regulations existed in each country in EU territory and to secure smooth distribution
of products of which safety is guaranteed. It is mandatory by law that products distributed and sold in EU territory to have
CE mark which shows that the product conforms with the requirements of EC Directive. Each EC Directive describes the
scope of apparatuses to which that EC Directive is applied. M-System’s R7D must conform with EMC Directive.
Each Directive states only basic requirements. In order to mark the CE on an assembled machinery equipment, its manufacturer needs to check the overall conformity with Directives applicable to it.
■ WARNINGS AND CAUTIONS WHEN INSTALLING THE R7D
The R7D needs to be installed in a control panel. This is effective not only to ensure general safety but also to contain noise
emissions by the R7D inside the control panel. We conduct a series of testing to see that the product conforms to EMC Directive while it is installed in the control panel.
Warning and cautions when installing R7D are stated below.
•Use control panels with an internal panel plate, both made of metal, when installing the R7D.
•Make sure to adequately ground the control panel and the internal panel plate with a thick cable to maintain low impedance
at high frequency.
•Use shielded cables for the signals taken out of the control panel.
•When painting the internal plate of the control panel, apply masking to expose metal surface to secure conductivity at the
sections where the following parts are attached:
- Bolts attaching the internal panel to the control panel
- Earth clamp on the shielded cable
•Noise emissions inside the control panel might leak through its openings. Design them as small as possible. Recommended
diameter is 10 cm or less.
Supplement:
Additional measures may be taken depending upon actual installation sites. These points of cautions are illustrated in the
next page.
•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 R7D Series
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.
Keep the opening for
ventilation as small as
posible.
Attach an electromagnetically shielded
filter when noise leaks
through the opening.
Keep the opening
for cabling as small as
possible.
To external apparatus
Use (e.g.) a shield cover
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.
Install an electromagnetically
shielded gasket when
noise leaks through

by using an electromagnetically shielded

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

■ WARNINGS AND CAUTIONS WHEN LAYING CABLES
Signal cables connected to the R7D contain high-frequency components. Since these cables has the same effect as an antenna, they emit these high-frequency components to the external space as noise or overlaps noise from the external space
on themselves.
Cables with shielding should be used for the signal line due to the above reason.
EMC conformance test is conducted in the condition that shielded cables and earth clamps are used with the R7D.
Warning and cautions when laying cables are stated below. These points of cautions are illustrated in the next page.
•Use shielded cables for those signal cables installed out of the control panel and for thermocouple and RTD extension
wires.
•All the network cables connected to R7D should be shielded.
•Use exclusively designed network cables for the DeviceNet.
•Expose the shield at a part of the cable cover, clip it with an earth clamp, and ground it to the internal panel of the control
panel. A drain wire connected to the panel in a pig-tail form cannot maintain low impedance against high-frequency noise,
thus grounding (noise shielding) in this form will not be effective.
Supplement:
Additional measures may be taken depending upon actual installation sites. These points of cautions are illustrated in the
next page.
•Keep cables as short as possible. It prevents noise emissions from the cables and noise overlapping to the cables.
•Attach a ferrite core to reduce noise impact to the signal cables susceptible to the noise. Ferrite core can be attached close
to the cable outlet of the control panel or close to the I/O terminal or connector, whichever is more effective. Also, the impact
might be reduced by winding the cable around the ferrite core for extra turns or attaching multiple ferrite cores.
•Keep cables which are easily affected by noise away from those which can be a noise source.

DC Signal Cable

Often subject to noise interference.
In the following are examples of effective ways to lay cables separately:
•Keeping physical distance (farther than 20 cm from motor drive cables, farther than 10 cm for other groups).
•Dividing off by a grounded metal plate
•Grouping into separate grounded metal pipes or cable shields.
Wires on each side of a filter should not be too close to each other. Noise could ride onto the other side of cable.
Extra attention needs to be paid at the following parts.
•Noise filter that is enclosed in power cables.
•Ferrite core that is attached to signal cables.
•Noise limiting circuit (surge quenching circuit, transient absorber circuit, etc.) that is enclosed in signal cables.
