4.4.2 Parallel configuration
This 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, TM4 has no specific recommendations on how to achieve optimum
configuration but coolant liquid pressure must not reach or exceed 30 PSI.
See the System Specifications [5] for estimated pump requirements.

management.
