Electric shocks can cause serious injuries and even death. The electrical connections must be made by qualifi ed technical personnel. Carry
out grounding before proceeding with other electrical connections.
External unit electrical connections
The electrical panel of the outdoor unit is located at the front of the form, after removing the front panel.
The power cable can be connected to the terminal block shown in the fi gure, using a core hitch. If the hole on the unit is not large enough, make
it bigger.
Check that the fastening of the power supply cable and the connecting cable between HYBRID MODULE and external unit are properly secured
using a cable locking device, freely commercially available, in order to ensure that no contact occurs between the cables and hot piping. This block
must also ensure good tensile strength.
