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.
