Eaton DPU222R Terminal Lug Allowable Connections

[jchester404]

Hello - I'm looking to help determine how many connections are allowed on my AC disconnect terminal lugs - Eaton DPU22R. I'm not seeing anything in the documentation answering this question. I've contacted their technical support but the person did not know as well. Here is the particular documentation: https://www.eaton.com/us/en-us/skuPage.DPU222R.html

I have a Ditek surge protect that I'm looking to put on this disconnect, but I'm not sure if I can install the wiring directly to the terminal lug that has the load line of the AC or if I should pigtail it. Is there any way for me to determine terminal lug allowable connections without looking at the documentation?

For reference - the AC load lines are 6 AWG and the surge protectors are 12 AWG.

Thank you for any help
