2.5 Connections and interfaces
2.5.1 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 sys-
tem that meets these requirements. If necessary, you can ask your local energy supply
company what the system impedance is. Observe the country-specic regulations when
making connections (e.g. in Germany DIN VDE 0100 with earth leakage circuit breaker).
