I understand Darkwoods Tri idea now by using an interface box and flexi conduit.
These drives do ‘learn’ the motor on a one time basis. They just turn them a 1/2 turn while measuring the windings and other things that are beyond me.

ABB drive Motor ID run for DTC by any chance?

Don't forget the thermostat protection an circuitry linked with the drive for atex requirements.

There aren't many vsds on the market you can just wire the motor thermostats and use it's inbuilt features to comply with regs.

We have external Siemens modules that are certified in the panel. Seems schnieders top of the range drive excluded have this feature!

Forced ventilation is not required, the smaller ones runs 40~60Htz.

The mind boggles when I try to imagine how forced ventilation would be implemented in an ATEX environment!

Pretty easily actually, why would you think otherwise?

Most of the Draw-works on drilling rigs are by forced ventilation tbh.
