Default ICEpower 200ASC ground connection


I need your advice on ground connection idea for my recently bought ICEpower 200ASC module. I'll be using it as DIY monoblock power amplifier in full balanced configuration and the problem is that I have limited idea on where to connect ground to metal chassis. Basically there are 3 ground connections possible to make ie. module ground point, mains plug (earth) and signal ground PIN1 of XLR connection. While I'm quite certain that GND must be connected to chassis at module point and mains plug side I'm not sure of connection at XLR plug. To make things even more complicated I've seen in other ICE models designing manuals that XLR PIN1 should be connected to chassis anyway but I think with all 3 ground connections a ground loop will be created.

Could you advise on best solution, please. Thank you.
