2.3.3 Connecting the service contacts
NOTE: Do not connect the voltage and ground outputs to an external voltage source.
The plug-in screw terminal blocks of the service contacts may be removed or inserted dur-
ing operation of the device.
The mGuard rs4000/rs2000 Switch has three digital inputs and outputs. These are config-
ured in the web interface, e.g., as a control signal for starting and stopping VPN connec-
tions.
The digital inputs and outputs are connected as follows.

Example
A push button or an on/off switch (e.g., key switch) can be connected between service
contacts CMD V+ and CMD.
The contacts ACK (+) and FAULT (+) are non-floating, continuously short-circuit-proof
and supply a maximum of 250 mA.
The switching inputs and switching outputs can be connected with signals from external de-
vices, e.g., with signals from PLCs. In this case, ensure the same potential as well as voltage
and current specifications are defined.
Depending on the firmware version used, the service contacts can be used for various
switching or signaling tasks.
