The use of an amplifier module listed below requires forced air cooling.
In this case, provide a fan motor.
When forced air cooling is provided, the power magnetics cabinet should
be designed so that cooling air from the fan motor does not leak out from
the cabinet.
Because of its operating environment, the fan motor may have to be
maintained or replaced. Therefore, special considerations should be
given to the installation and construction of the fan motor so that
maintenance work can be performed easily.
