TIDA-01513: High voltage measurement

Part Number: TIDA-01513

Hi Team,

Our customer would like to clarify about Figure 3 of the TIDA-01513 reference design which states that 400V/800V of high voltage measurement is possible but the voltage tolerance of the relay (1462041-7) used in the circuit diagram is rated at 220VDC. He is concerned whether the relay can be used in the 400V application. He would like to know if it is possible to measure 400V insulation resistance with the components shown in this circuit diagram.
