3.4.1 Functional earthing XV300

CAUTION
SAFELY DIVERTING ELECTRICAL INTERFERENCE CURRENTS
HMI panel XV300The must be connected to a central earth point with a
conductor that is as short and has as low a resistance as possible.
Ground connection characteristics:
l
Wire cross-sectional area ≧ 1.5 mm², length ≦ 350 mm
The XV300 needs to be connected to the conductive structure in, e.g.,
the control panel using the central earth point (earthing screw). This
method of earthing is mandatory required for proper function.
Assemble and terminate the functional earth conductor in advance.
Unscrew the earthing screw on the enclosure.
Put the earthing connection cable's eyelet in position.
Use a torque of 1.3 Nm (11.5 lb-in) to tighten the earthing screw on the enclosure.
