DANGER
The AC switch may not be operated manually under any circumstances. If this warning is not followed, the
safety of personnel and equipment cannot be guaranteed.
Ingeteam accepts no liability for the consequences of non-compliance with this warning.
Use the PPE listed in section "Personal Protective Equipment".
CAUTION
See section "Important safety instructions" before operating the equipment.
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.
Following the steps below gives safe, no-load disconnection, maximizing the life of any electro-mechanical
components in the inverter.

20.1. Process of shutting down the unit

To carry out any maintenance task on the unit involving access to the inside, it is necessary to disconnect the unit
and isolate any source of voltage. All operations performed on the inverter for disconnecting it must be done on the
DCAC connections module. Proceed in the following order to disconnect voltage sources safely:
1. Stop inverter on the display. The unit disconnects, stopping to inject AC power.
2. Press the emergency stop button. Pressing the emergency stop button causes the motorized DC switch to
open.
3. Wait 10 minutes for the unit´s capacities to discharge before entering into the unit.
4. Access the DCAC connections module via the folding door.
5. Check that the AC thermomagnetic circuit breaker is in OFF.
6. The OFF position of the AC thermomagnetic circuit breaker must be locked to prevent any reconnection.
To do this, press the OFF button on the thermomagnetic circuit breaker and turn and remove the locking
key.
