Grounding and Shielding
The main grounding point at the AMC2-4R4 is connected to pin 2 of the power supply
connector - see Connecting Diagrams, page 102.
It is good practice to shield all wires carrying low level signals.
The main grounding point at the AMC2-4W is connected to pin 2 of the power supply
connector - see Connecting Diagrams, page 102.
It is good practice to shield all wires carrying low level signals.
The AMC2-4R4 allows you to create a central ground or shielding point, simply by setting
certain jumpers. Set these jumpers only if grounding or shielding is not achieved by other
means.

Notice!
In the second and third case the jumper on the bottom side of the AMC2-controller must to
be set - see the installation manual of the AMC2-4W.
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.

If the AMC2-4R4 has its own power - as in the third example in Overview - Power supply/
consumption, page 49 - the shield will be connected to pin 2 of the power supply
connector - see Connecting Diagrams, page 102.
If the extension module is powered from the AMC2 controller - as in the second example
in Overview - Power supply/consumption, page 49 - the connection should be made as in
the RS-485 for extension modules, page 65 diagram.
If more than one extension module is to be connected to an AMC2 controller, and all of
them to receive power from it as well, then use the RS-485 extension interface for the
connection.
