(5) Measures against static electricity for commercially available CompactFlash
cards in compliance with the EMC directives
The C Controller system may be affected by static electricity discharged to a commercially
available CompactFlash card.
The following explains an example of static electricity countermeasures for commercially available CompactFlash
card.
Although information in this section is based on the requirements and standards of current regulations, it does not guarantee
that the entire machinery constructed according to the information will comply with the EMC Directive.
The compliance with the EMC Directive must be finally confirmed by the manufacturer of each machinery.
(a) Preventive measure example
Attach an insulation sheet to the CompactFlash card. All the metal part except the terminal part must be
covered with the insulation sheet as shown below. Be sure not to protrude the insulation sheet on the
CompactFlash card surface or the grooves (connector guide) in the sides of the CompactFlash card. The
CompactFlash card may not be able to be inserted in C Controller module.
