General dangers of failing to follow the safety instructions
This is a state-of-the-art device that is safe to operate. The device may pose
residual dangers if it is installed or operated incorrectly.
Exercise caution when pressing the keys that control movable system parts
such as conveyor systems, flaps, etc. Before pressing these buttons, make
sure that no persons are in the danger zone of moving system parts!
The weighing terminal must not be used in a potentially explosive atmosphere.
It is the responsibility of the owner of the equipment to classify potentially ex­
plosive areas (division into zones, equipment groups, temperature classes,
etc.). Local labor inspection authorities and technical inspection agencies can
be of assistance here!
The power input terminals of the device must be connected to a safety extra
low voltage (12-30 V
power supply (e.g. serial interfaces), care must be taken to ensure that only
safety extra low voltages are used in such cases as well!
The weighing terminal contains a lithium battery for storing the data that is en­
tered. 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 recom­
mended by the manufacturer. Dispose of used batteries in accordance with the
manufacturer's instructions.
Notices:
S 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).
S All metallic parts of a system must be thoroughly grounded to prevent a
static charge buildup. Moving parts, such as portable scales on plastic
wheels, must be grounded with ground clamps or ground leads of
appropriate diameter.
