Chapter 2 Preparing for Installation

Maintaining Safety with Electricity

Warning

Before working on a chassis or working near power supplies, unplug the power cord on AC units;

disconnect the power at the circuit breaker on DC units.

Statement 12

Follow these guidelines when working on equipment powered by electricity:

• Before beginning procedures that require access to the interior of the chassis, locate the emergency

power-off switch for the room in which you are working. Then, if an electrical accident occurs, you

can act quickly to turn off the power.

• Do not work alone if potentially hazardous conditions exist anywhere in your work space.

• Never assume that power is disconnected from a circuit; always check the circuit.

• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power

extension cables, frayed power cords, and missing safety grounds.

• If an electrical accident occurs, proceed as follows:

–

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 5500-X models equipped with AC-input power supplies 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.

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 anti-static strap, which should be between

one and 10 megohms (Mohms).
