Figure 8-7 shows the Switch is in the UTILITY position and utility source voltage is available.
•
Rated utility source voltage is available to the transfer switch terminal lugs N1 and N2 through sensing wires to
the ATS controller through the CAT5 wire to the inverter.
•
Utility voltage is available from N2 to Terminal N2A of the transfer switch.
•
Utility voltage is available from N1A to the normally closed contact of the internal transfer relay (TR). From the
