CAUTION
INTERFERENCES
Screw all plug-in connections or lock them into place in order to improve
screening.
Signal cables must not be routed in the same cable duct with power cables.
Before putting the system into operation, check all cable connections to
make sure that everything has been wired properly.
Make sure that all voltages and signals have the required values as spe-
cified in the technical data.
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.
l
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.
CAUTION
SHORT-CIRCUIT HAZARD
If the XV300 Touch Panel is or has been exposed to environmental fluc-
tuations (ambient temperature, air humidity), condensation may form on or
inside it. As long as this condensation is present, there will be a short-circuit
hazard.
Do not switch on the XV300 Touch Panel when it has condensation in or on
it.
If the XV300 has condensation in or on it, or if the panel has been exposed
to environmental fluctuations, let the panel settle into the existing ambient
temperature before switching it on. Do not expose the XV300 Touch Panel
to direct thermal radiation from heating appliances.
Before connecting the power supply
CAUTION
24 VDC power supply for integrated DC-to-DC converter.
The voltage being applied must meet the requirements for safety extra-low
voltages (SELV) set forth in IEC 60950 and the requirements for protected
extra-low voltages (PELV) set forth in ICE/UL 61010-2-201.
Observe the polarity!
NOTICE
Arrange for an electrician to install the Plug connector MSTB 2.5/3-ST-5.08
and connect the power supply.
The XV300 Touch Panel has an internal fuse and protection against polarity reversal.
The power supply for the XV300 Touch Panel is not galvanically isolated.
