WARNING
Potential equalization currents
Large equalization currents between the protective ground systems of different de-
vices may cause operational malfunctions due to signal interference and may even
cause fires.
If necessary, a potential equalization conductor should be installed parallel to the
cable. This should have a cross-section that is a multiple of the cable shield.
CAUTION
Operational malfunctions
Use of unsuitable or improperly prepared cables, as well as incorrect wiring will
mean that neither the values stated in the technical data nor the electromagnetic
compatibility (EMC) can be ensured.
Only use cables prepared by specialists.
The cables used must be prepared according to the interface description in this
document.
The wiring instructions for the relevant interface must be observed when wiring
the device.
Any generally applicable regulations and standards must be fulfilled.
CAUTION
