Ethernet cable
Use shielded cables for the cables which are connected to the module and run out from the control panel. If a shielded cable
is not used or not grounded correctly, the noise immunity will not meet the specified value.
■Ethernet cable
A shielded cable is used for the Ethernet cable. Strip a part of the jacket as shown below and ground the exposed shield in the
largest possible area.

■Grounding the cable clamp
Use shielded cables for external wiring and ground the shields of the external wiring cables to the control panel with the
AD75CK-type cable clamp (Mitsubishi). (Ground the shield section 20 to 30cm away from the module.)
For detail on AD75CK, refer to the following.
 AD75CK-type Cable Clamping Instruction Manual
External power supply
• Use a CE-marked product for an external power supply and always ground the FG terminal. (External power supply used
for the tests conducted by Mitsubishi: TDK-Lambda DRJ100-24-1)
• Use a power cable of 30m or shorter when connecting it to the module power supply terminal.

■Ferrite core
A ferrite core has the effect of reducing radiated noise in the 30MHz to 100MHz band.
It is recommended to attach ferrite cores if shielded cables coming out of the control panel do not provide sufficient shielding
effects.
Note that the ferrite cores must be attached at the position closest to the cable hole inside the control panel. If attached at an
improper position, the ferrite core will not produce any effect.
For the terminals that are connected to the external power supply, attach a ferrite core 4cm away from the module.
For the AnyWireASLINK cable, install a ferrite core at a point as close to the AnyWireASLINK terminal block of this product as
possible.
Wrap the cable around the ferrite core by one as shown below.
(Ferrite core used for the tests conducted by Mitsubishi: TOKIN Corporation ESD-SR-250, TDK Corporation ZCAT3035-1330)
