4. Electrical connection and operation
4.1. Electrical connection
• When operating this electric measuring transducer, the national regulations (e.g.
Germany VDE 0100 "Conditions for the erection of power installations with nominal
voltages below 1000 volts") must be observed during installation and selection of the
electrical conductors.
The following format applies only for MCR-S-10-50-...:
• The measuring line fed through the module has to feature at least basic insulation.
• Y : A wire voltage of 300 V AC or DC toward earth may not be exceeded on the
measuring line!
• Δ : With three-phase alternating current, a line voltage of 519.6 V may not be exceeded!

4.2. Start-up
Before putting this measuring transducer into operation, please ensure that the
configuration data comply with the requirement.
The configuration data for a preconfigured device are to be found on the right hand side of the housing.
When using a non-configured measuring transducer, a standard configuration that can be found in
"7.1. Order key" is set.
Should the desired configuration not match that on the label on the side or the standard configuration,
please observe the following point, "Functional diagram for configuration".
