In this case new coolant is constant given in and directly given out. The coolant can
be contaminated very easily with this kind of water cooling, consequently the open
cooling circuit is not recommended.

Dependent on the power unit and overload capacity the inverter Off-temperatures
are 60° C and 90° C. To ensure a safe operation the coolant output temperature
must be 10 K under „Overheat"- function.
