The power input terminals of the device must be connected to safety extra low
voltage (12…30 V
DC
). When connecting external components with their own
power supply (e.g. serial interfaces), care must be taken to ensure that only
SELV is used in that case as well! This applies to variants with 12…30 VDC
power supply.
The weighing terminal contains a lithium battery for storing the data that is
entered. There is a risk of explosion if the battery is replaced incorrectly. It
must only be replaced with the same type of battery, or an equivalent type
recommended by the manufacturer. Dispose of used batteries in accordance
with the manufacturer's instructions.
Notices:

All switching devices (e.g. relays and contactors) that are connected or in
the immediate vicinity must be wired to effective noise filters (RC filters,
free-wheeling diodes).

In order to avoid static charge buildup, all metallic parts of a system must
be thoroughly grounded. Moving parts, such as portable scales on plastic
wheels, must be grounded with ground clamps or ground leads of
appropriate diameter.
