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.
A shielded cable is used for the network cable. Strip a part of the jacket as shown below and ground the exposed shield in the
largest possible area.
(1) Network cable
■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.)
20 to 30 cm
(2) Inside the control panel
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 10m or shorter when connecting it to the module power supply terminal.
• Use a power cable of 30m or shorter when connecting it to the external power supply for output part.
• Use a power cable of 3m or shorter when connecting it to the noise filter from the external power supply for output part.
