Caution to conform with EC Directives
• Installation in Enclosure
Programmable logic controllers are open-type devices that must be installed and used within conductive
control cabinets. Please use the programmable logic controller while installed within a conductive shielded
control cabinet. Please secure the cabinet door to the control cabinet (for conduction).
Installation within a control cabinet greatly affects the safety of the system and aids in shielding noise from
the programmable logic controller.
• Control cabinet
- The control cabinet must be conductive.
- Ground the control cabinet with the thickest possible grounding cable.
- To ensure that there is electrical 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.
• Note for compliance with EN61131-2: 2007
General note on the use of the power supply cable.
The FX
3U
-1PG unit requires that the cable used for power supply is 30 m or less.
• The shield of the twisted pair cable used for the FP, RP, PG0, and CLR signal wires should be grounded at
both ends of the cable.
• Please attach a ferrite core less than 200 mm from the other end of the FP, RP, PG0, and CLR signal
wires. The ferrite core should be a product equivalent to ZCAT3035-1330 by TDK Corp.
