General Safety Practices

Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD occurs when
electronic components are improperly handled; it can result in complete or intermittent failures.
Always follow ESD-prevention procedures when removing and replacing components.
• Ensure that the chassis is electrically connected to earth ground.
• Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact.
• Connect the clip to the ESD-strap connection jack (to the left of the power switch on the rear of the
chassis) or to an unpainted chassis frame surface.
For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10
megohm (Mohm).
Caution
