Figure 30. Pressure loss, CH7x
The liquid carrying hoses from the network to the cooling elements of the drive must not be
electrically conductive. Risk of electrical shock and device damage! To avoid electrochemical
corrosion, it is necessary to add an inhibitor (e.g. Cortec VpCI-649l in the cooling liquid.
The following main line hose materials are allowed for a liquid cooled drive including an aluminum
heatsink:
