Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It may

occur if electronic printed circuit cards are improperly handled and may cause complete or

intermittent failures. Always follow ESD prevention procedures when removing and replacing

modules:

■Ensure that the data concentrator chassis is electrically connected to earth ground.

■Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the

clip to an unpainted surface of the chassis frame to channel unwanted ESD voltages safely to

ground. To guard against ESD damage and shocks, the wrist strap and cord must operate

effectively.

■If no wrist strap is available, ground yourself by touching a metal part of the chassis.

Caution: For the safety of your equipment, periodically check the resistance value of the

antistatic strap. It should be between 1 and 10 megohms (Mohm).
