Figure 7.2.
Location of components of the electrical panel for heat pumps with three-phase power supply
(400 V / 50 Hz, 3/N/PE~).
The internal components of the heat pump are connected to the electrical panel with terminal blocks for quick
standing connections. For more detailed information about the electrical panel connections, see sections
12.3 to 12.5.
The electrical installation necessary to use the heat pump is only the power cord connection, control signals,
external temperature probes and external control valves.
7.1. POWER SUPPLY
Depending on the model, the heat pump may require single-phase 230 V / 50 Hz, 1/N/PE ~ or , three-phase
400 V / 50 Hz, 3/N/PE ~ power supply. To carry out the electrical installation, follow the following steps.
1. Insert the power cord through the cable grommet located at the bottom of the rear cover of the heat
pump. In order to do this, it is necessary to remove the front and side covers (see section 3.5).
2. Lead the cable through the cable grommet located at the left top of the electrical panel, fixing the
cable properly to the structure.
3. Connect the power supply cord following Figure 7.3 in single-phase models and following Figure 7.4
in three phase models (see also sections 12.3 to 12.5).
