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.
