3.4 - ELECTRICAL CONNECTIONS

Before carrying out any intervention, make sure that all the power supplies are
disconnected.
• These operations are only allowed for specialized personnel.
• Carry out electrical connections respecting the installation manual, the wiring
diagram and the local laws.
• The heat pump has 3 separate power supply circuits. The internal unit has a
main power supply circuit and an auxiliary heaters power supply circuit.
The external unit has a single power supply circuit.
• Envisage separate power supplies, one for each circuit.
• Envisage an appropriate interruption with fuses or magnetothermic switch
for each power supply.
• Envisage a suitable ground for each power supply.
• Envisage a earth leakage breaker for each power supply.
• Use specific cables for power supplies.
• Only use copper cables.
• The cables must be equipped with cap terminals of the proportionate section
• Check that the mains voltage and frequency values respect what is indicated
on the plate data of the heat pump.
• The external and the internal units need to be connected with each other
through a communication line.
• Envisage a path of the communication cable separate and far from the power
supply lines
• Use a screened and specific cable for data lines
• Use a single cable from the internal unit to the external unit, without interme-
diate junctions
• Connect the screen of the communication cable to the ground of the internal
unit
• Firmly secure the cables to the respective clamps
• Check that the cables are not subject to excessive tractions.
• Firmly secure the cables to the respective cable ties
The power supply lines must be dimensioned adequately to avoid voltage drops
or overheating of cables or other devices located on the lines themselves.
