4.4.2 Parallel configuration
This cooling configuration involves the MCU and motor being cooled in parallel.
As the cooling units are supplied by the vehicle integrator and the cooling system setup involves fine-tuning
and testing at the customer site, Dana TM4 has no specific recommendations on how to achieve optimal
configuration but coolant liquid pressure must not reach or exceed 30 PSI.
See the System Specifications [4] for coolant flow rate and estimated pump requirements.

4.4.3 Serial configuration
Although it is recommended that you use a parallel cooling configuration, a serial cooling configuration can
also be used in your integration, see Figure 4.
Note: Coolant liquid pressure must not reach or exceed 30 PSI.
See the System Specifications [4] for coolant flow rate and estimated pump requirements.
