Shielded lines

The ACS-8 devices are daisy-chained together using shielded cables.
Use Cat 5 cables or higher.
The shielding of the incoming line connects to the shield terminal bar of the ACS-8. The shielding of the
outgoing line must not be connected.
The shield terminal bar in each ACS-8 must be connected to a separate PE.
(min. cable cross-section 1,5mm²)
When it is not possible to provide a mains earth connection at each device on a 12V system, then a three
core cable should be used to provide the 12V DC power and an earth continuity conductor.
The shielding of the reader line is connected on one side to the shield terminal bar in the ACS-8.
The above points also apply to the ACS-8 module bus.
