In the UPS modules:
Q1 Input isolation circuit breaker, used to isolate the UPS module from the main
AC input (mains 1) source and provide input current protection.
Q5N UPS isolation circuit breaker, used to isolate the UPS module from he attached load.
K3N Inverter output contactor (automatic), used to isolate the inverter when it is off.
In the circuit of the battery of each UPS module:
