2. Use a true RMS voltmeter to make sure that there is no difference in potential between L1 IN and L1 OUT, L2 IN and L2 OUT, and L3 IN and L3 OUT on the Q3 circuit breaker. The Q3 circuit breaker must be in the OFF position. The top side of Q3 will be utility voltage and the bottom side of Q3 will be the voltage from the UPS in static bypass. Voltage should be less than 2 volts.
Q3 is a 4-pole circuit breaker. Be sure to measure L1 to L1, L2 to L2, and L3 to L3. Note
