Potential Electrostatic Charge Hazard

! WARNING

ELECTROSTATIC CHARGE HAZARD

RISK OF PERSONAL INJURY OR EQUIPMENT DAMAGE.

Potential for electrostatic charging hazard.

Installations and maintenance tasks performed in potentially hazardous areas must be performed only

after the area has been verified to be free of hazardous materials, atmospheres, and conditions.

Circuit boards contain devices that are susceptible to damage when exposed to electrostatic charges.

Damage caused by obvious mishandling of the board will void the warranty. To avoid damage, observe

the following precautions in the order given.

• Do not discharge static electricity onto the circuit board. Avoid tools or procedures that would subject

the circuit board to static damage. Some possible causes of static damage include ungrounded

soldering irons, nonconductive plastics, and similar materials.

• Use a suitable grounding strap before handling or performing maintenance on a printed circuit board.

• Transport and store circuit boards in electrically conductive bags or foil.

• Use extra caution during dry weather. Relative humidity less than 30% tends to multiply the

accumulation of static charges on any surface.
