ESD Protection Procedure
A wrist strap is provided for use by operator.
1. ESD protection is established when the ESD device is connected to earth ground. This can be
achieved by having a common ground point on the workstation that is connected to earth ground.
2. A ground block located on your workstation can provide the connecting point of the ESD device. It
is important to keep all ESD surfaces clean and scratch-free, as well as connected to the ground block
at all times. Clean surfaces periodically using a plain cotton cloth with a good ammoniated detergent.
Dust and dirt may cause conditions that cause electrostatic discharge.
WARNING! DO NOT USE CLEANING MATERIALS CONTAINING WAX OR
AGGRESSIVE SOLVENTS THAT MAY MODIFY THE ELECTRICAL PROPERTIES
OF THE SURFACE.
DO NO USE THE THIRD WIRE GROUND IN AN ELECTRICAL OUTLET TO
PROVIDE ESD PROTECTION. EARTH GROUND IS PROVIDED USING A BRASS
STUD WITH A ONE HUNDRED MEG OHM RESISTOR IN LINE.
