■ 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.
