Important information
WARNING
L
imited safety due to buffering elements
The target safety-related level may not be achieved in the event of non-compliance.
►
Do not use any buffering elements in a Flexi Line system, such as CAN bridges,
CAN repeaters or CAN-capable optical photoelectric sensors.
►
Do not use any other components except Flexi Line stations in a Flexi Link system.
NOTICE
O
vervoltage at the Flexi Line inputs
The device may be damaged if this is not observed.
►
Observe the maximum permissible voltage at the Flexi Line inputs of ±30V (to
terminal A2=GND).
Approach
1. Connect the NEXT connection of each station to the PRE connection of the next
station.
2. Connect the identically named terminals with one another, i.e. A with A and B with
B.
