DANGER
STRAY CURRENTS
Large equalizing currents between the functional earthing sys-
tem 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 device may be damaged by potential differences.
▶
The GND terminals of all bus modules must be connected.
▶
Do not connect the connector to the device 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 device is de-energized.
Avoid writing to SD cards. Reasons:
•
SD cards have a limited number of write cycles.
•
If there is a voltage drop while a write operation is in prog-
ress, data loss is highly likely to occur.
▶
Remove the SD card only when the device is de-energized.
▶
Before switching off the device, make sure that there are
no programs writing to the SD card.
