Observe coolant flow rate
► Fall below => no sufficient cooling.
►
Exceeding => heat sink is washed out.

Table 18: Technical data coolant
1)
The coolant inlet temperature must always be ≥ than the ambient temperature. A temperature difference
between drive inverter and ambient temperature can lead to condensation at high humidity. Moisture con-
densation is dangerous for the drive inverter. The drive inverter can be destroyed through occuring short-cir
-
cuits. The user must guarantee that any moisture condensation is avoided!
