Power supply must be equipped with grounding and 30 mA differential protection.
• Use the cable-gland and the pass-throught provided inside the HP for the passage of the cable.
• As this heat pump is installed outdoors, it is mandatory to pass the cable through a protective sheath for this purpose. The power supply of the HP must be
fitted with a protection device in accordance with the legislation in force.
• The electric cables must be buried at a depth of 50 cm (85 cm under a road or a path) in an electrical sheath (red corrugated). When a cable buried in a
sheath crosses another cable or a pipe (gas, water, etc.) The distance between them must be greater than 20 cm.
