5.2. Heat pump power supply
All the models in the ecoGEO HP range require three-phase power, 3/N/PE 400 V / 50 Hz.
The heat pumps should be powered by an external automatic breaker that shuts down all the circuits. Shown below are the
recommended cable diameters for each heat pump model and the recommended range of external electric thermal-magnetic
protection. Maximum heat pump electrical consumption can vary widely depending on working conditions; for more information,
please refer to the Technical Service Manual.

To carry out the electrical installation, insert the power cable through the rear cover of the heat pump and pass it to the bottom
right part of the heat pump. Continue by connecting the cables to the power terminal block of the heat pump, as described below.
