3 Basic Information (General)
3.1 Documentation
These installation instruction contain all data necessary for placing and
commissioning the weighing bridges KERN KFP V20.
In combination with a display unit, described below as weighing system, for operation
configuration, please refer to the operating instructions of the display unit.
3.2 Proper use
The balance you purchased is intended to determine the weighing value of material
to be weighed. It is intended to be used as a “non-aut o matic bal ca nce”, i.e. the
material to be weighed is manually and carefully placed in the centre of the weighing
plate.. As soon as a stable weighing value is reached the weighing value can be
read.
3.3 Improper Use
Do not leave permanent load on the weighing bridge. This may damage the
measuring system.
Impacts and overloading exceeding the stated maximum load (max) of the weighing
system, minus a possibly existing tare load, must be strictly avoided. T he weighing
system could be damaged.
Never operate in an explosive environment. The serial version is not explosion
protected.
Changes to the weighing system's design are not permitted. This may lead to
incorrect weighing results, safety-related faults and destruction of the balance.
The weighing system unit may only be operated in accordance with the described
default s ettings. Other areas of use must be released by KERN in writing.
3.4 Warranty
Warranty claims shall be voided in case
• Our conditions in the operation manual are ignored
• The appliance is used outside the described uses
• Structural changes of the device
• Mechanical damage and damage caused by media, liquids
• Natural wear and tear
• The appliance is improperly set up or incorrectly electrically connected
• Overload of the measuring system

3.5 Monitoring of Test Resources
Carefully read this operation manual before setup and commissioning,
even if you are already familiar with KERN balances.
In the framework of quality assurance the measuring-related properties of the
weighing system and, if applicable, the testing weight, must be checked regularly.
The responsible user must define a suitable interval as well as type and scope of this
test. Information is available on KERN’s home page (www.kern-sohn.com with regard
to the monitoring of weighing system test substances and the test weights required
for this. In KERN's accredited DKD calibration laboratory test weights and weighing
systems may be calibrated (return to the national standard) fast and at moderate
cost.
4 Basic Safety Precautions
4.1 Pay attention to the instructions in the Operation Manual
4.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
The installation of a display unit must only be carried out by a well acquainted
specialist with the workings of weighing balances.
5 T ransport and storage
5.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the
appliance itself when unpacking for possible visible damage.
5.2 Packaging / return transport
Keep all parts of the original packaging for a possibly
required return.
Only use original packaging for returning.
Prior to dispatch disconnect all cables and remove
loose/mobile parts.
Reattach possibly supplied transport securing devices.
Secure all parts agains t shi fting and damage.

6 Unpacking, Setup and Commi s si oning
6.1 Installation Site, Location of Use
The weighing bridges are designed in a way that reliable weighing results are
achieved in common conditions of use.
You will work accurately and fast, if you select the right location for your weighing
system.
On the installation site observe the following:
• Place the weighing system on a firm, level surface.
The floor at the installation site must be able to carry safely the weight of the
maximally loaded weighing bridge at the resting points. At the same time it
should be sufficiently stable, that no vibrations may occur during weighing
work.
• In the installation site possibly no vibrations, e.g. by neighbouring machines
should occur.
• Do not use the weighing system in an explosive environment.
• Avoid extreme heat as well as temperature fluctuation caused by installing
next to a radiator or in the direct sunlight.
• Protect the weighing system against direct draughts e.g. due to open windows
and doors.
• Use weighing system only in dry environment, protect it against high humidity,
vapours and dust.
• Do not expose the device to extreme dampness for longer periods of time.
Non-permitted condensation (co ndensation of air humidity on the appliance)
may occur if a cold appliance is taken to a considerably warmer environment.
In this case, acclimatize the disconnected appliance for ca. 2 hours at room
temperature.
• Avoid jarring during weighing.
• Avoid static charge of goods to be weighed or weighing container.
• Keep away chemicals (such as liquids or gasses), which could attack and
damage the balance inside or from outside.
• Keep IP protection of the device.
• Major display deviations (incorrect weighing results) may be experienced
should electromagnetic fields (e.g. due to mobile phones or radio equipment),
static electricity accumulations or instable power supply occur. Change
location or remove source of interference.
