Emergency Disconnect Location

[Power Solutions]

Hi All,
We were recently asked to complete a project that was started by another firm. Those are always fun.
Single phase 120/240 V from the utility.
Three phase 230 V from a digital converter to at 10hp propane pump motor.
Question one. Is there a code requirement for the emergency shut off relay to be before or after the converter?
The converter is only used for this one pump.
Both options are in the same non-hazardous location.
I believe either location is ok. Thoughts?

Second question. 514.11 states an emergency shut off need to be between 20 and 100 ft away for the dispenser. The intent seems to be able to allow a person to shut the system down if there is an issue without being in the class 1 division 2 zone. Can a second emergency shut off be installed in the class 1 Division 2 zone?

Code wants an emergency shut off between 20 and 100 ft away. Does not prohibit additional shut offs. Last tank/dispenser had 2, one at the required distance, and one closer in. All devices met the installation requirements.

Is this a motor fuel dispensing location? If not 514 likely does not apply. If you are only filling portable containers I don't know it would be considered motor fuel dispensing unless you actually are connecting to a container that is fixed to a vehicle?

It may. See 515.10.
