2 single pole contactors instead of one 2 pole contactor

DC bus is about 810VDC which feeds a bunch of inverters. I am trying to isolate the DC bus from inverters. I understand that even one contactor will open the circuit, but the reason I want to open both leads is to completely isolate the inverter to be safe for maintenance. I just want to have complete isolation, electrically and mechanically.
