CAUTION:
Check the resistance of the ESD-preventive wrist strap for safety. The resistance reading should be in the
range of 1 to 10 megohm (Mohm) between human body and the ground.
EMI
All electromagnetic interference (EMI) sources, from outside or inside of the firewall and application
system, adversely affect the firewall in a conduction pattern of capacitance coupling, inductance
coupling, electromagnetic wave radiation, or common impedance (including grounding system)
coupling. To prevent EMI, note the following guidelines:
•
Take measures against interference from the power grid.
•
Do not use the firewall together with the grounding equipment or light-prevention equipment of
power equipment, and keep the firewall far away from them.
•
Keep the firewall far away from high-power radio launchers, radars, and equipment with high
frequency or high current.
NOTE:
Use electromagnetic shielding when necessary.
Lightning protection
To protect the firewall from lightning better, do as follows:
•
Make sure the grounding cable of the chassis is well grounded.
