Chapter 2 Preparing for Installation
General Site Requirements
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.

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.
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).
Working in an ESD Environment
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. Always follow ESD-prevention procedures when you remove and replace
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 grounding clip to
an unpainted surface of the chassis frame to safely ground unwanted ESD voltages. To guard against
ESD damage and shocks, the wrist strap and cord must operate properly. If no wrist strap is
available, ground yourself by touching the metal part of the chassis.
