• Control cabinet
- The control cabinet must be conductive.
- Ground the control cabinet with the thickest possible grounding cable.
- To ensure that there is electric contact between the control cabinet and its door, connect the cabinet and its doors with
thick wires.
- In order to suppress the leakage of radio waves, the control cabinet structure must have minimal openings. Also, wrap
the cable holes with a shielding cover or other shielding devices.
- The gap between the control cabinet and its door must be as small as possible by attaching EMI gaskets between them.
*1 These wires are used to improve the conductivity between the door and control cabinet.
• Cables
- Make sure to use shielded cables as cables pulled out of the control cabinet.
- Connect the shield such as shielded cables and shielding covers to the grounded control cabinet.
• It is possible that the accuracy temporarily fluctuates within 10 %.
Perform the following when using the FX5-4AD-ADP:
• Set the number of times of winding to "2 turns" within approximately 200 mm from terminal block of the analog cable on the
FX5-4AD-ADP side, and attach a ferrite core. (Ferrite core used in our test: E04SR401938 manufactured by SEIWA
ELECTRIC MFG. CO., LTD.)
Perform the following when using the FX5-4DA-ADP:
• Set the number of times of winding to "2 turns" within approximately 200 mm from the connectors of the power cable on the
FX5-4DA-ADP side, and attach a ferrite core. (Ferrite core used in our test: E04SR401938 manufactured by SEIWA
ELECTRIC MFG. CO., LTD.)
• The FX5-4DA-ADP requires that the cable used for power supply is 30 m or less.
■Caution for when the built-in Ethernet port is used
• Use a shielded twisted pair cable for the 10BASE-T or 100BASE-TX cable. Strip a part of the jacket of a shielded twisted
pair cable as shown below, and ground as much of the exposed shield as possible to both sides of the cables.
• Connect a ferrite core to both ends of the cable. (Ferrite core used in tests by Mitsubishi: ZCAT2035-0930A manufactured
by TDK Co.)
