Figure 2-11: Example PI-Diagram of Cooling System and Connections

Table 2-7 shows the speciﬁcations related to the cooling agent and its circulation. Also see

Table 1-4, Technical Information on Page 1-9.

Table 2-7: Information About Cooling Agent and Its Circulation

A = 100% water; B = Water/Glycol mixture 80:20; C = Water/Glycol mixture (60:40)

Deﬁnitions: Min. liquid ﬂow = Minimum ﬂow rate to ensure of total venting of the cooling

element

Nom. liquid ﬂow = Flow rate while running the drive at I

Max. liquid ﬂow = If ﬂow rate exceeds max. liquid ﬂow, risk of cooling element

erosion increases

Note: Unless minimum liquid ﬂow rate is ensured, air pockets may develop in the cooling

elements.
