2.6.1 Electrical connection
Observe the country-specific regulations when connecting (e. g. in Germany DIN VDE 0100
with residual current circuit breaker).
This appliance is intended for operation on an electrical power system with a system imped-
ance Z
max
of a maximum of 0.292 ohm at the point of transfer (service line). The operator
must ensure that the cooled incubator is operated only on an electrical power system that
meets these requirements. If necessary, you can ask your local energy supply company what
the system impedance is.
