Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage occurs
when electronic components are improperly handled and can result in complete or intermittent failures.

•
Working in an ESD Environment
•
– Use caution; do not become a victim yourself.
Disconnect power from the system.
–
If possible, send another person to get medical aid. Otherwise, assess the condition of the
–
victim, and then call for help.
Determine whether or not the person needs rescue breathing or external cardiac compressions;
–
then take appropriate action.
Use the ASA chassis within its marked electrical ratings and product usage instructions.
Install the ASA in compliance with local and national electrical codes as listed in the REgulatory
Compliance and Safety Information document.
The ASA models equipped with AC-input power supplies are shipped with a 3-wire electrical cord
with a grounding-type plug that fits only a grounding-type power outlet. Do not circumvent this
safety feature. Equipment grounding should comply with local and national electrical codes.
The ASA 5500-X models equipped with AC-input power supplies and are shipped with a 3-wire
electrical cord with a grounding-type plug that fits into a grounding-type power outlet only. Do not
circumvent this safety feature. Equipment grounding should comply with local and national
electrical codes.
Always follow ESD-prevention procedures when removing and replacing components. Ensure that
the chassis is electrically connected to an earth ground. Wear an ESD-preventive wrist strap,
ensuring that it makes good skin contact. Connect the grounding clip to an unpainted surface of the
chassis frame to safely ground ESD voltages. To properly guard against ESD damage and shocks,
the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by
touching the metal part of the chassis.
For safety, periodically check the resistance value of the antistatic strap, which should be between
1 and 10 megohms (Mohms).
