AC Circuit Breaker (CB1) Operation
The internal AC circuit breaker can be opened by accessing the small door on
the transformer assembly as shown in Figure 1-1 on page 1–4. The
PUSH TO OPEN
button (see Figure 1-9) will open the internal AC circuit breaker and interrupt the
main AC grid connection to the inverter. The
PUSH TO CLOSE button is not the
preferred method for energization of AC to the inverter. Perform a controlled
shutdown or energization by using the
ENABLE/DISABLE switch.
DC Switch (S1)
The Xantrex GT500 is equipped with a DC switch to disconnect the incoming
power (see Figure 1-10). Opening DC switch (S1) causes the Xantrex GT500 to
execute an immediate and orderly shutdown, open the AC circuit breaker, and
report a PV disconnect fault detection on the display. However, if you must
perform a controlled shutdown while the inverter is operating, use the
ENABLE/
DISABLE switch rather than the S1 switch.
