2. Safety instructions
2.3 Device-specific hazards
to wire the corresponding port/interface.
All general Directives and standards must be complied with.
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.
DANGER
STRAY CURRENTS
Large equalizing currents between the functional earthing system and the
ground system of different devices may result in fire or in malfunctions due
to signal interference.
If necessary, route an equipotential bonding conductor, with a cross-sectional
area that is several times larger than that of the cable shielding, parallel to the
cable.
CAUTION
NON-GALVANICALLY-ISOLATED INTERFACES
The XV300 may be damaged by potential differences.
The GND terminals of all bus modules must be connected.
Do not connect the connector to the XV300 or disconnect it without first de-
energizing the system.
CAUTION
DATA LOSS
If the SD card is being written to and a voltage drop occurs or the card is
removed, data may be lost or the SD card may be ruined.
Insert the SD card only when the XV300 is de-energized.
Avoid writing to SD cards. Reasons:
l
SD cards have a limited number of write cycles.
l
If there is a voltage drop while a write operation is in progress, data loss is highly
