Pin 1 D37 EMS 220

[Inverted]

I have a Vertical Power VPX system and a dual SV700, I want to know where would be the best pick up point for Pin 1 on the EMS D37, I am thinking that the main supply terminal on the VPX , or would the switched side of the Master Relay be better?
I am a little confused with this Pin because there is a post that suggests that this does not need to be connected at all for SV to read voltage.
Thanks.

VP-X supplies the system voltage to Skyview so the EMS D37 pins 1 and 2 are redundant when you have VP-X. However, you can still use the EMS D37 pins 1 and 2 to read the voltage instead of VP-X or at other places. If you have an auxiliary battery or emergency bus you could use the EMS pins to measure the voltage there. See the discussion here:
