Example of the interconnection of cooling circuits
The following figure shows two examples for the series connection of different cooling
circuits: On the left, all cooling circuits of the motor are connected in series. On the right, the
cooling circuits of the primary section precision cooler and the primary section main cooler of
a motor form a series connection. The resulting cooling circuits are connected in parallel.
The secondary section cooling systems of both motors are also connected in series.

NOTICE
Corrosion as a result of unsuitable materials used to connect the cooler
Corrosion damage can occur if you use unsuitable materials to connect to the cooler.
• We recommend that you use brass or stainless steel fittings when connecting the
