Safety notes

When carrying out service or repair work, always observe the following:
1.5 Environmental protection
FTx/ITx-SH-e-0720
• Before opening the scale, isolate it from the AC power line (pull out the plug).
• The scales contain precision electronic components that are sensitive to elec-
trostatic discharge. We recommend that you wear a grounding wrist strap
when doing any work in the interior of the scale, in order to prevent any
electrostatic charge building up. Grounding wrist straps are commercially
available from electronic component suppliers.
• Servicing work in explosion hazard zones is strictly prohibited! Ignition
power could inadvertently be generated, causing an explosion. Servicing work
should therefore only be undertaken in secure areas. Please also observe all
special instructions in this service manual relating to work on instruments that
are approved for use in potentially explosive environments. Such instructions
are indicated by the adjacent symbol.
Disposal of rechargeable batteries
Please note all current environmental directives when disposing of the terminal. If
the terminal is equipped with a rechargeable battery: The nickel-metal-hydride
(NiMH) storage battery may not be disposed of in the normal refuse. Please
observe local regulations when disposing of environmentally harmful materials.
Disposal of electronic components
Dispose of defective components in strict compliance with all local and national
regulations! In many countries electronic components are classified as hazardous
waste for whose disposal there are special regulations. In some countries
electronic components are collected separately for recycling. If necessary, find out
the applicable regulations from the local authorities!
