20. EMC AND LOW VOLTAGE DIRECTIVES
(2) MELSECNET (II) and MELSECNET/10 modules
(a) Use double-shielded coaxial cables (MITSUBISHI CABLE INDUSTRIES, LTD.:
5C-2V-CCY) for the MELSECNET modules (such as AJ71AR21, AJ71QBR11)
which uses coaxial cables. Radiated noise in the range of 30 MHz or higher can
be suppressed by using double-shielded coaxial cables. Ground the double-
shielded coaxial cable by connecting its outer shield to the ground.
Refer to (1) for grounding of the shield.
(b) Always attach a ferrite core to the double-shielded coaxial cable connected to
the MELSECNET module. In addition, position the ferrite core on each cable
near the outlet of the control panel. The ZCAT3035 ferrite core (TDK) is
recommended.
(3) Ethernet module
Precautions to be followed when AUI cables
*1
, twisted pair cables and coaxial cables
are used are described below.
(a) Be sure to ground the AUI cables connected to the 10BASE5
connectors.Because the AUI cable is of the shielded type, as shown in the figure
below, partly remove the outer sheath, and ground the exposed shield section to
the widest possible surface.
Refer to (1) for the grounding of the shield.
(b) Use shielded twisted pair cables as the twisted pair cables
*1
connected to the
10BASE-T connectors. Partly strip the outer sheath of the shielded twisted pair
cable, and ground the exposed shield section to the widest possible area as
shown below.
Refer to (1) for the grounding of the shield.
*1
Make sure to attach a ferrite core to the cable.
As a ferrite core, the ZCAT2035 manufactured by TDK is recommended.
