TVSS Enclosure mounting height

[winslowfam]

Good morning. We are specifying a surge protective device for each of a client's two 800A main panels. The problem is that the only wall space for these SPD cabinets is directly underneath the main panels...there is a vertical height avalable from the floor to the bottom of each main panel of 27" and the SPD cabinets are 12" square. I read in the NEC that breakers and disconnect switches have a maximum height restriction (<= 6'7") but don't see anywhere a restriction on being mounted too low. The area around these main panels is protected by bollards and there is no chance of flooding. Any commnets on this low mounting height?

I see no issues with the available wall space.

There is no minimum hieght that they need to meet, and I dont think there is a max hieght either as long as it dosen't have a "handle". All of them I have installed have had fuses in them but them but no disconnecting handle, the disconnect was always in the panel not the TVSS.
