20.3. Inverter shutdown from the emergency stop button

For the case of an unexpected situation, these units have an emergency stop button. When pressed, the following
actions are performed:
1. If the unit is connected to the grid, the inverter will stop switching and disconnect the grid connection AC
thermomagnetic circuit breaker.
2. Opening of the motorized DC switch.
It will not be possible to start inverter operation again until the emergency stop button has been returned to its
original position.
DANGER
This shutdown procedure does not guarantee complete disconnection of all sources of voltage connected to the
unit, hence accessing the inside of the unit after performing this shutdown is prohibited. If you wish to gain
access to the inside of the inverter, follow the procedure in Section "20.1. Process of shutting down the unit".
CAUTION
The inverter's electro-mechanical elements have a limited number of operating cycles for on-load disconnection.
A large number of disconnections or instantaneous trips leads to higher wear in them, which can lead to
undesirable, early deterioration.

20.4. Inverter shutdown by opening a door

These units have a safety system whereby, using a limit switch, the unit switches to shutdown status and is
automatically disconnected from the PV array and electricity grid when a door is opened with the unit running. The
opening of a folding door is equivalent to activating the emergency pushbutton.
Until it has been ensured that all the unit's doors have been closed correctly, it cannot be returned to the operating
condition again.
DANGER
This shutdown procedure does not guarantee complete disconnection of all sources of voltage connected to the
unit, hence accessing the inside of the unit after performing this shutdown is prohibited. If you wish to gain
access to the inside of the inverter, follow the procedure in Section "20.1. Process of shutting down the unit".
CAUTION
Ingeteam accepts no liability for the consequences of tampering with the safety system.
The inverter's electro-mechanical elements have a limited number of operating cycles for on-load disconnection.
A large number of disconnections or instantaneous trips leads to higher wear in them, which can lead to
undesirable, early deterioration.
