Table 2-8 will help you to determine the appropriate flows of cooling agent (GPM) with given
power losses (see Page 1-6).
Table 2-8: Cooling Agent Flow Rates (GPM) in Relation to Power Loss at Certain Glycol/
Water Mixture
Table 2-9: Coolant Volumes and Temperatures
Note: In order to ensure sufficient cooling of boards, capacitors and DC-buses, Liquid-Cooled
drives of chassis CH4 are equipped with one additional fan per module. The fan is
placed underneath the module and it is supplied externally. See Page 2-18.
