For Your Safety
Your new Kontron product was developed and tested carefully to provide all features necessary to ensure its
compliance with electrical safety requirements. It was also designed for a long fault-free life. However, the life
expectancy of your product can be drastically reduced by improper treatment during unpacking and installation.
Therefore, in the interest of your own safety and of the correct operation of your new Kontron product, you are
requested to conform with the following guidelines.
High Voltage Safety Instructions
As a precaution and in case of danger, the power connector must be easily accessible. The power connector is the
product’s main disconnect device.
Warning
All operations on this product must be carried out by sufficiently skilled personnel only.
Electric Shock!
Before installing a non hot-swappable Kontron product into a system always ensure that
your mains power is switched off. This also applies to the installation of piggybacks. Serious
electrical shock hazards can exist during all installation, repair, and maintenance operations
on this product. Therefore, always unplug the power cable and any other cables which
provide external voltages before performing any work on this product.
Earth ground connection to vehicle’s chassis or a central grounding point shall remain
connected. The earth ground cable shall be the last cable to be disconnected or the first
cable to be connected when performing installation or removal procedures on this product.
Special Handling and Unpacking Instruction
ESD Sensitive Device!
Electronic boards and their components are sensitive to static electricity. Therefore, care
must be taken during all handling operations and inspections of this product, in order to
ensure product integrity at all times.
Handling and operation of the product is permitted only for trained personnel within a work
place that is access controlled. Follow the “General Safety Instructions” supplied with the
product.
Do not handle this product out of its protective enclosure while it is not used for operational purposes unless it is
otherwise protected.
Whenever possible, unpack or pack this product only at EOS/ESD safe work stations. Where a safe work station is not
guaranteed, it is important for the user to be electrically discharged before touching the product with his/her hands
or tools. This is most easily done by touching a metal part of your system housing.
It is particularly important to observe standard anti-static precautions when changing piggybacks, ROM devices,
jumper settings etc. If the product contains batteries for RTC or memory backup, ensure that the product is not placed
on conductive surfaces, including anti-static plastics or sponges. They can cause short circuits and damage the
batteries or conductive circuits on the product.
