and Relay 1 is configured as a normally open Normal Relay, which receives
commands from an automation controller to energize the contactor coil.

For Control Module firmware v3.000 and higher, the E300 Electronic Overload
Relay can also be wired as a Control Relay in which the relay that is controlled by
the communications network opens when a trip event is present. Figure 44
is a
wiring diagram of a Non-Reversing Starter with Relay 0 configured as a Control
Relay. Relay 0 receives control commands from an automation controller to
energize or de-energize the contactor coil. Relay 0 also goes to an open state when
there is a trip event.
