5.2.2 Cooling system connections
The external cooling system must be connected to each one of the cooling elements of the inverter
or AC drive.
NOTE! Do not connect the cooling elements in series.
The delivery comprises hoses (Technobel Noir Tricoflex, Art.no 135855) 1.5 m in length and 16 mm
in diameter (CH5, CH6, CH7). The hoses are inserted in 1400-mm UL94V0 approved conduits (type
HFX40). These hoses have screw type connectors with internal thread. The connection of the hoses
is made on the aluminium adapter (external thread) of the cooling element. The customer end
thread of the cooling hose is G1/2" male fixed including a Usit-R sealing. When you make the
connection of the line hose, avoid any twisting of the hose on the element.
