After tripping initiated by the "Push to trip" button or by
the undervoltage (MN) release or the shunt (MX)
release, device reset can be automatic, remote or
manual.

The diagram is shown with circuits deenergised, all devices open, connected and
charged and relays in normal position.
Following tripping due to an electrical fault (with an
SDE contact), reset must be carried out manually.

Opening, closing and reset orders are transmitted via the communication network.
The "Enable automatic reset" and "Enable reset even if SDE" parameters must be
set using the RSU software via the screen by clicking the blue text.
"Auto/manu" is a switch on the front of the motor mechanism.
