CAUTION
Connection concept
When operated together, multiple remote displays must be connected to a
common GND potential. For this purpose, the GND signal must always be
carried along in the bus wiring.
Potentially live contacts must be protected against touch. Therefore, take
care that the remote display is connected via the "Bus-In"
Fig. 4). This ensures protection of the live contacts on "Bus-Out"
(see
means of the jack (for the IP type of protection, please refer to chapter 4.1).
Termination
Faulty or missing termination
Faulty or missing termination or level specification results in communica-
tion errors and can destroy the drive's electronic system.
` Make sure that termination is correct and test it.
Termination and level specification RS485
If termination and level specification do not occur in the bus master, they
must be carried out externally.
