Insulation Monitoring Devicemonitoring device for Electric Vehicleelectric vehicle

Good day to all!

I am planning on designing an Electric Vehicleelectric vehicle architecture from scratch. My main DC bus voltage is 400V400 V. However, I have got different voltages in my system. I have got a 600/400V400 V buck converter to supply my air conditioning compressor and I have got a Motor Invertermotor inverter that outputs 3 phase AC supply.

To make myself clear, I am attaching an image of my High Voltage Junction Boxhigh voltage junction box. enter image description here

With this architecture, I have a confusion about monitoring the insulation resistance of my High Voltage Bushigh voltage bus. I am currently planning to keep an Insulation Monitoring Deviceinsulation monitoring device (IMD) from Bender (Isometer IR155-3203).

I would like to know whether I need separate IMDs for my 400V400 V supply to the Airair conditioning as well as the 3 phase AC supply to my Motormotor. Do I need to be concerned about multiple voltages in the same system? If not, what can I do detect a break in the insulation at any point in my HV bus? I hope my question makes sense, if it doesntdoesn't please let me know.
