CAUTION
SAFELY DIVERTING ELECTRICAL INTERFERENCE
CURRENTS
HMI panel XV300 must be connected to a central earth point with a con-
ductor that is as short and has as low a resistance as possible.

Ground connection characteristics:
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). For trouble-free
operation, this type of grounding is mandatory.
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.
