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 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.
