Appendix 6 EMC and Low Voltage Directives
■ AnyWireASLINK master module
• For the grounding of the RJ51AW12AL and routing of the power supply cable, provide a ground point to the control panel
near the power supply module. Then, ground the LG terminals of the transmission cable terminal block to the ground point
with the thickest and shortest ground cable possible (2 or less, a length of 30cm or shorter).
• For the cable connected to the transmission cable terminal block, install a ferrite core with the damping characteristics, the
ZCAT3035-1330 (manufactured by TDK Corporation) or equivalent, within 20cm from the transmission cable terminal block
of this product. Wrap the cable around the ferrite core by one as shown below.
• Use a CE-marked power supply to which the module power supply or external power supply is connected. Ground the FG
terminals.
• Keep each power cable connected to the external power supply terminal or module power supply terminal to 30m or less.
• Use the RJ51AW12AL in the zone B.
* 1
*1 Zone defines categories according to industrial environment, specified in the EMC and Low Voltage Directives, EN61131-2.
■ CANopen module
• Ground shields of CAN bus cables at the both ends of the network. When grounding the shields, check for the potential
difference between the grounding points to secure the safety. Take a measure to prevent a damage if the potential
difference is detected.
• CAN bus cable is a shielded cable. Strip a part of the jacket of the cable as shown below and ground the exposed shield to
the area of 35mm or more.

• Zone C: Factory main power supplies (isolated from public power supplies by dedicated transformers)
• Zone B: Dedicated power distribution, secondary surge protection (Rated voltage: 300V or less)
• Zone A: Local power distribution, protected from dedicated power distribution by AC/DC converters and insulation transformers (Rated voltage: 120V or less)
