Connections and interfaces
2.6.1 Electrical
connection
This appliance is intended for operation on an electrical power system with a system
impedance Zmax at the point of transfer (service line) of a maximum of 0.292 Ohm.
The operator must ensure that the appliance is operated only on an electrical power
system that meets these requirements. If necessary, you can ask your local energy sup-
ply company what the system impedance is. Observe the country-speci
fi
c regulations
when connecting (e.g. in Germany DIN VDE 0100 with residual current circuit breaker).
2.6.2 Communication
interfaces
The interfaces are intended for appliances which meet the requirements of IEC 60950-1.

fi
tted by default with a USB port in accordance with the USB speci
fi
ca-
tion. With this you can:
