Safety Requirements
WARNING
Static electricity collects on non-conductors such as paper, cloth, or plastic. A static
discharge can be damaging even though you often cannot see or feel it.
The following safety precautions must be observed to insure product and personal safety and prevent damage to
circuit boards and/or components:
♦
Always wear an ESD wrist strap when handling ESD sensitive material and be sure it is properly
connected.
♦
Keep circuit boards and components away from non-conductors.
♦
Keep clothing away from circuit boards and components.
♦
Keep circuit boards in anti-static bags.
♦
Be cautious when AC power is exposed when working on an assembly.
♦
Always use an ISOLATION TRANSFORMER when diagnosing any terminals, monitors or power
supplies when AC power is applied.
♦
Be cautious of very high voltage potentials when working with monitors.
There should be an approved insulating mat (for technician safety) in front of any workbench where monitors,
terminals or power modules are being serviced when power is applied.
NOTE Do NOT wear ESD straps when working on terminals,monitors or power supplies
when AC power is applied. This is to avoid the hazard of electrical shock.
