ASIC wiring and plug questions

This should be an easy one for you guys.
I just received a KS1 that i need to run on 240v. I have a 30a 240v circuit wired that will be dedicated to the KS1 alone, so i will not need a PDU.
I have a Meter Box otw that comes with a 6-30 receptacle and wired plug.

The KS1 has a single C14 connection. Do i just need a C13 to 6-30 plug cable? Seems simple enough, but i’m too paranoid to run with this decision without confirmation.

Maybe the question i need to ask is the input to the KS1 take two 110v legs and one common?
