• The gen-set is stopped instantly
• The gen-set cannot be started from the unit (see next table)

In addition to the actions defined by the fail classes, it is possible to activate
one or two relay outputs, if additional relays are available in the unit.
The fail class ‘trip and stop’ will only deload the gen-set before opening the
breaker, if option G5 (power management) is included.
