4. Safety Instructions
4.1.
Electrostatic Discharge (ESD)
A sudden discharge of electrostatic electricity can destroy static-sensitive devices or micro-circuitry. Proper packaging
and grounding techniques are necessary prerequisites for avoiding damage. Always take the following precautions:
1.
Transport printed circuit boards in static-safe containers such as boxes or bags.
2.
Keep electrostatic sensitive parts in their containers until they arrive at a static-free station.
3.
Always be properly grounded when touching a sensitive PCB, component, or assembly.
4.
Store electrostatic-sensitive PCB’s in protective packaging or on conductive foam.
4.1.1.
Grounding Methods
Guard against electrostatic damage of the device by taking the following preventative steps:
1.
Cover workstations with approved anti-static material. Provide a wrist strap connected to a work surface and properly
grounded tools and equipment.
2.
Use anti-static mats, heel straps, or air ionizers for added protection.
3.
Handle electrostatic-sensitive components, PCB’s, and assemblies by the case or the edge of the board.
4.
Avoid contact with pins, leads, or circuitry.
5.
Turn off power and input signals before inserting and removing connectors or test equipment.
6.
Keep the work area free of non-conductive materials such as ordinary plastic assembly aids and Styrofoam.
7.
Use field service tools, such as cutters, screwdrivers, and vacuum cleaners that are conductive.
8.
Always lay drives and PCB’s with the component-side down on the foam.

Instructions for the Lithium Battery
The ETX baseboard is equipped with a Lithium battery (CMOS battery). For replacing the Lithium battery, please
observe the instructions described in chapter 6.8.2 ”Replacing the Lithium Battery”.
Warning
Danger of explosion when replaced with wrong type of battery. Replace the battery only with UL listed
Lithium battery that has the same or equivalent type recommended by Kontron.
Do not dispose of used CMOS batteries in domestic waste. Dispose of the battery according to the
local regulations dealing with the disposal of these special materials (e. g. to the collecting points for
disposal of batteries).
