Caution
In order to avoid inadvertent short circuits, please ensure that the module is disconnected from the
power supply, before you establish connections.
The ground connections on the module (GND
I
) are only for the multifunctional inputs (I1-I8). The ground
connection for an output (O1-O8) has to be installed externally.
When measuring voltage on voltage supplies whose ground does not correspond to the ground of the
Mini Module, please select the floating voltage measurement (I1&2 and I3&I4).
Please observe correct polarity for connection and wiring of the device.
