• Connect the unit's electrics to the power network as per the table above.
• Connection to the machine's general disconnect switch located inside it (Ø 22.2 blanking cover provided).
• For sections between 0.75 and 2.5 mm2, a H 05 VV-F type cable may be used, otherwise the cable must be type H 07 RN-F.
• The power supply cable must be sized in accordance with current standards and regulations.
• The supply cable must be secured using the anchorage provided (located between the disconnect switch and the Ø 22.2
blanking cover). Once the supply cable has been fed through and connect, tighten the clamp fully and cut the end extending
past the clamp.
• Respect the current assigned to the disconnect switch for the air handling unit.
• The leakage current may reach 13 mA. Earthing is essential. Each unit is equipped with 2 earth terminals (PE) indicated by
the logo
, one close to the disconnect switch, and the other on one of the unit's feet. Both terminals must be permanently
connected.
