5.3.2 Grounding (Potential equalization)
Grounding (Potential equalization)!
In case of a non existing grounding or that the grounding of the
printer is not carried out properly, this could cause serious injury or
death and it can also cause malfunctions or damages at the printer!
These dangers or demolitions can happen for example because of
electrostatic discharge (ESD) or potential difference.
Specially for countries without existing protected earth connection, there is a
special grounding point located at the side of the printer.
This threaded socket must be connected to ground if there is no ground pin in the
mains socket/plug.
The threaded case is sealed inwards and thus IP 65 conform. With a screw and a
ring terminal (cable lug) the grounding can be fixed easily.
Please note, that the grounding point (7) is hidden behind the round
grounding-symbol-label (6) on the lower left hand side of the cabinet
of the printer.

A separate grounding line (min. cable cross-section 2,00 mm
