4.6 Grounding and shielding
The main grounding point at the extension is connected to pin 2 of the power supply
connector. For more information on these connections, refer to chapter Connecting
diagrams, page 37.
It is good practice to shield all wires carrying low level signals.
If the extension is powered by the controller, as in number 2 of Overview - Power supply/
consumption, page 18, the connection should be made as shown in the connection diagram
of RS-485 interface, page 20.
Notice!
The functional earth ground symbol identifies a functional part that allows installing
an electrical system in an electromagnetically compatible manner.
Notice!
If the shield is set in the extension, the appropriate jumpers for shielding must also be set
in the controller. See the corresponding installation manuals of the controller.
Notice!
Risk of malfunction
Ensure that no ground loops are formed.
Notice!
In general the following apply:
If the devices have their own power supplies, the shielding is applied to one side only. The
free end should be insulated to avoid inadvertent connections.
If one device is fed power by another, the cable shielding should be applied to both sides.
