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.

If possible, send another person to get medical aid. Otherwise, assess the condition of the victim
–
and then call for help.
Determine if the person needs rescue breathing or external cardiac compressions; then take
–
appropriate action.
Use the PIX security appliance within its marked electrical ratings and product usage instructions.
Install the PIX security appliance in compliance with local and national electrical codes as listed in
the Regulatory Compliance and Safety Information
PIX security appliance models equipped with AC-input power supplies are shipped with a three-wire
electrical cord with a grounding-type plug that fits only a grounding-type power outlet. This is a
safety feature that you should not circumvent. Equipment grounding should comply with local and
national electrical codes.
PIX security appliance models equipped with DC-input power supplies must be terminated with the
DC input wiring on a DC source capable of supplying at least 15 amps. A 15-amp circuit breaker is
required at the 48 VDC facility power source. An easily accessible disconnect device should be
incorporated into the facility wiring. Be sure to connect the grounding wire conduit to a solid earth
ground. We recommend that you use a closed loop ring to terminate the ground conductor at the
ground stud.
Other DC power guidelines are listed in the
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 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).
