2.6 Connections and interfaces
2.6.1 Electrical connection
This appliance is intended for operation on an electrical power system with a system
impedance Z
of a maximum of 0.292 ohm at the point of transfer (service line). The
max
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 supply com-
pany what the system impedance is.
Observe the country-specific regulations when making connections (e.g. in Germany DIN
VDE 0100 with earth leakage circuit breaker).
