Safety messages
DANGER
Turn off the main electrical disconnect switch prior to servicing any of the boxes.
Failure to do so might lead to serious injury or death.
Always use extreme caution when measuring voltage or performing procedures that require a
module to be powered on.
Electrostatic discharge prevention when manipulating a printed circuit board
(PCB)
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 on a PCB-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.
For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and
10 megohm (Mohm).
