How to wire an AC voltmeter
Installation of single phase system
To measure the line-to-line voltage, connect the phases two by two to the signal lamp. In this way, to measure the voltage level between phases R and S, you must connect phase S to pin X1 and phase R to pin X2 of signal lamp number 1. Do the same for the other two signal lights, i.e. connect ST phases to signal light #2 and RT phases to signal light #3.
