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.
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.

1/ General Safety Instructions for IT Equipment
Please read this chapter carefully and take careful note of the instructions, which have been
compiled for your safety and to ensure to apply in accordance with intended regulations. If
the following general safety instructions are not observed, it could lead to injuries to the
operator and/or damage of the product; in cases of nonobservance of the instructions
Kontron is exempt from accident liability, this also applies during the warranty period.
The product has been built and tested according to the basic safety requirements for low voltage (LVD) applications
and has left the manufacturer in safety-related, flawless condition. To maintain this condition and also to ensure safe
operation, the operator must not only observe the correct operating conditions for the product but also the following
general safety instructions:
The product must be used as specified in the product documentation, in which the instructions for safety for the
product and for the operator are described. These contain guidelines for setting up, installation and assembly,
maintenance, transport or storage.
The on-site electrical installation must meet the requirements of the country's specific local regulations.
If a power cable comes with the product, only this cable should be used. Do not use an extension cable to connect
the product.
To guarantee that sufficient air circulation is available to cool the product, please ensure that the ventilation
openings are not covered or blocked. If an air filter is provided, this should be cleaned regularly. Do not place the
system close to heat sources or damp places. Make sure the system is well ventilated.
Only devices or parts which fulfill the requirements of SELV circuits (Safety Extra Low Voltage) as stipulated by
IEC 60950-1 may be connected to the available interfaces.
Before opening the device, make sure that the device is disconnected from the mains.
Switching off the device by its power button does not disconnect it from the mains. Complete disconnection is
only possible if the power cable is removed from the wall plug or from the device. Ensure that there is free and
easy access to enable disconnection.
The device may only be opened for the insertion or removal of add-on cards (depending on the configuration of
the system). This may only be carried out by qualified operators.
If extensions are being carried out, the following must be observed:
All effective legal regulations and all technical data are adhered to.
The power consumption of any add-on card does not exceed the specified limitations.
The current consumption of the system does not exceed the value stated on the product label.
Only original accessories that have been approved by Kontron can be used.
Please note: safe operation is no longer possible when any of the following applies:
The device has visible damages.
The device is no longer functioning.
In this case the device must be switched off and it must be ensured that the device can no longer be operated.

KBox F-420-WLU - User Guide, Rev. 1.0
www.kontron.com // 14
Additional safety instructions for DC power supply circuits
To guarantee safe operation of devices with DC power supply voltages larger than 60 volts DC or a power
consumption larger than 240 VA, please observe that:
the device is set up, installed and operated in a room or enclosure marked with ‘‘RESTRICTED ACCESS’’, if
there are no safety messages on product as safety signs and labels on the device itself.
no cables or parts without insulation in electrical circuits with dangerous voltage or power should be
touched directly or indirectly
a reliable protective earthing connection is provided
a suitable, easily accessible disconnecting device is used in the application (e.g. overcurrent protective
device), if the device itself is not disconnectable
a disconnect device, if provided in or as part of the equipment, shall disconnect both poles simultaneously
interconnecting power circuits of different devices cause no electrical hazards
A sufficient dimensioning of the power cable wires must be selected -- according to the maximum electrical

1.1. Electrostatic Discharge (ESD)
A sudden discharge of electrostatic electricity can destroy static-
sensitive devices or
micro-circuitry.
Therefore proper packaging and grounding techniques are necessary precautions to prevent damage. Always take the
following precautions:
1. Transport boards in ESD-safe containers such as boxes or bags.
2. Keep electrostatic sensitive parts in their containers until they arrive at the ESD-safe workplace.
3. Always be properly grounded when touching a sensitive board, component, or assembly.
4. Store electrostatic-sensitive boards in protective packaging or on antistatic mats.
1.1.1. Grounding Methods
By adhering to the guidelines below, electrostatic damage to the device can be avoided:
1. Cover workstations with approved antistatic material. Always wear a wrist strap connected to workplace. Always
use properly grounded tools and equipment.
2. Use antistatic mats, heel straps, or air ionizers for more protection.
3. Always handle electrostatically sensitive components by their edge or by their casing.
4. Avoid contact with pins, leads, or circuitry.
5. Turn off power and input signals before inserting and removing connectors or connecting test equipment.
6. Keep work area free of non-conductive materials such as ordinary plastic assembly aids and Styrofoam.
7. Use only field service tools which are conductive, such as cutters, screwdrivers, and vacuum cleaners.
8. Always place drives and boards PCB-assembly-side down on the foam.
1.2. Lithium Battery Replacement
If replacing the lithium battery, follow the replacement precautions stated below.
Do not ingest battery, Chemical Burn Hazard
This product contains a coin / button cell battery. If the coin / button cell battery is
