Connection of the current sensors

230 is not possible to use the sensor because the maximum 35 .
The power on single phase unit will be a lot more.
The three current sensors, one for each phase, are installed inside the group
fuse central as follows:
Every phase from the electricity meter feeding the electricity group central unit
is led through a current sensor before being fitted on the respective bar.
Wiring to the boiler is done according to the picture on the terminal block. In
this way the total phase current is constantly being checked and compared
with the amperage set on the loading monitor on the boiler. If the current is
higher, the control unit disconnects one electrical power stage. If it is still too
high, it disconnects yet another power stage etc. When the current again sinks
below the set value, the stages will be reconnected. The current detectors
together with the electronics thus prevent more power to be connected than
the main fuses can stand.
