tion of the operation controls for the 250-kW and 500-kW systems and Figure 12 on page

ENABLE/DISABLE–This toggle switch permits the operator to select whether the sys-
tem is enabled or disabled. With the switch in the Enable position, the system is enabled.
With the switch in the Disable position, the system is disabled. When the system is dis-
abled, the system will go to the Bypass Isolate state, connecting the utility to the load
though the bypass circuit breaker. The bypass circuit breaker will be closed and the input
and output isolation circuit breakers will be opened.
RESET–This pushbutton allows the operator to manually reset the system alarm(s).
When the system is in the Bypass state and the RESET pushbutton is pushed, all latched
alarm(s) will be reset if the alarm(s) have cleared.
