Cooling System Connections

The external cooling system shall be connected to each one of the cooling elements of the

drive.

Note: The cooling elements must NOT be connected in series.

The cooling elements are equipped with hoses (Technobel Noir Tricoﬂex, P/N 135855) 1.5m 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 aluminum adapter (external thread) of the cooling

element. Avoid any twisting of the hose on the element while connecting the line hose.

For all other chassis (CH3, CH4), the standard delivery includes fast connectors of type

“Tema”, series 1300 or 1900. The fast connectors are also available as an option also for CH5,

CH6, CH7.
