POINTS OF CAUTION

■CONFORMITY WITH EU DIRECTIVES

•The equipment must be mounted inside the instrument

panel of a metal enclosure.

•The actual installation environments such as panel con-

ﬁgurations, connected devices and connected wires may

affect the protection level of this unit when it is integrat-

ed in a panel system. The user may have to review the CE

requirements in regard to the whole system and employ

additional protective measures to ensure CE conformity.

•Install lightning surge protectors for those wires connect-

ed to remote locations. Choose a surge protector with its

maximum surge voltage 40V or less between lines. Rec-

ommended M-System model: MDP-D24.

■POWER INPUT RATING & OPERATIONAL RANGE

•Locate the power input rating marked on the product and

conﬁrm its operational range as indicated below:

24V DC rating: 24V ±10%, approx. 80mA

■GENERAL PRECAUTIONS

•Before you remove the unit or mount it, turn off the power

supply and input signal for safety.

■ENVIRONMENT

•Indoor use.

•When heavy dust or metal particles are present in the

air, install the unit inside proper housing with sufﬁcient

ventilation.

•Do not install the unit where it is subjected to continuous

vibration. Do not subject the unit to physical impact.

•Environmental temperature must be within -10 to +55°C

(14 to 131°F) with relative humidity within 30 to 90% RH

in order to ensure adequate life span and operation.

■WIRING

•Do not install cables close to noise sources (relay drive

cable, high frequency line, etc.).

•Do not bind these cables together with those in which

noises are present. Do not install them in the same duct.

■AND ....

•The unit is designed to function as soon as power is sup-

plied, however, a warm up for 10 minutes is required for

satisfying complete performance described in the data

sheet.

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 EU Directive. Each EU Directive describes the

scope of apparatuses to which that EU Directive is applied. M-System’s R7M must conform with EMC Directive.

Each Directive states only basic requirements. In order to mark the CE on an assembled machinery equipment, its manufac-

turer needs to check the overall conformity with Directives applicable to it.

■WARNINGS AND CAUTIONS WHEN INSTALLING THE R7M

The R7M 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 R7M inside the control panel. We conduct a series of testing to see that the product conforms to EMC Direc-

tive while it is installed in the control panel.

Warning and cautions when installing R7M are stated below.

•Use control panels with an internal panel plate, both made of metal, when installing the R7M.

•Make sure to adequately ground the control panel and the internal panel plate with a thick cable to maintain low imped-

ance at high frequency.

•Use shielded cables for the signals taken out of the control panel.

•Choose a thick and short cable to ground the FG terminal of the R7M module to the internal panel plate of the control panel.

Note: If electromagnetic radiation disturbance increases by grounding the FG terminal, remove the grounding.

•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

- Ground for the FG of the R7M module

- 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.

■WARNINGS AND CAUTIONS WHEN LAYING CABLES

Signal cables connected to the R7M contain high-frequency components. Since these cables has the same effect as an an-

tenna, 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 R7M.

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 R7M should be shielded.

•Use shielded cables for network communication.

•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.

Often being a noise source 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.
