Why is the bottom of a Low Voltage Dry type transformer would need to be left open when mounted in the ceiling?

Issue:

EX225T65H is mounted from the ceiling and the bottom is wide open. is there a reason that this would need to be left open like this?

Product Line:

Low Voltage Dry Type Transformers

Environment:

EX/EXN and EE transformers

Cause:

Product features clarification

Resolution:

The bottom of a transformer is open when mounted in the ceiling to allow proper evacuation of the heated air from the core/coil.

Transformers rated 225KVA and above in the J-style enclosures are switchboard construction, which means open bottoms. There will not be any bottom plates or covers.

SquareD/Schneider Electric does not offer any type of bottom plates or covers as accessory components.
