CAUTION
Non-isolated interfaces
The device may be damaged due to potential differences.
The GND terminals of all bus stations must be connected.
CAUTION
Data loss
During a write operation to a CF card/hard disk, this may lose data or may be de-
stroyed if there is a power failure or if it is removed.
Only insert and remove CF cards/hard disk when the device is in a de-energized
state.
Always secure CF cards with the CF slot cover.
Before switching off:
-
Ensure that no software write operations to a CF card/hard disk are in progress
(«CF ACT» and «HD ACT» LEDs must not be lit).
-
Shut down the operating system.
If possible, avoid write operations to CF cards/hard disk. Reasons:
-
The number of write cycles possible on CF cards is limited.
-
A power failure during write operations will most likely lead to loss of data.
If the writing of the CF card/hard disk cannot be avoided, use an uninterruptible
power supply (USP) to prevent data loss.
CAUTION
Device condensation
If the device is or was exposed to climatic changes (temperature fluctuation, air hu-
midity) moisture can form on or in the device (device condensation). In this case,
there is a risk of short-circuit.
The device must
not
be switched on when device condensation is present.
If condensation is present on the device, or if it was exposed to temperature fluc-
tuations, it must be allowed to adjust to room temperature (do not expose the de-
vice to the direct heat of heating devices) prior to commissioning.
CAUTION
UV light
When exposed to UV light, plastics can embrittle and the lifespan of the device is
reduced.
Protect the device against direct sunlight (UV rays).
