You can reduce the electrostatic hazards by minimizing the generation of
static electricity. For example, you have the following options to minimize
the generation of static electricity:
• Control the environmental humidity.
• Protect the device from direct airflow.
• Ensure a continuous drain off of the electrostatic charges.
Avoid inadmissibly high electrostatic charge of the metal housing
components on the device.
Include the metal housing components in the equipotential bonding.
