A.1.2 Installation Instructions for the EMC Standards
A PLC must be installed in a control box. The control box protects the PLC, and shields off the electromagnetic
interference generated by the PLC.
 Control box
- Use a conductive control box.
- To ensure that an inner plate contacts the control box well, users have to mask the paint on the bolts of the plate.
- To ensure that the control box is grounded well even if there is high-frequency noise, users have to connect the
control box with a thick wire.
