Shutting down the unit

13. Shutting down the unit
This section describes the procedure to shut down the unit. If you wish to work inside the unit, you must carry out
these instructions in the order shown here to remove the power.
1. Proceed to stop mode from the inverter display.
2. Remove AC voltage from a means of disconnection outside the unit.
3. Remove DC voltage from a means of disconnection outside the unit or using the unit switch, provided
the protection barriers protecting the DC supply are not going to be removed. Where these protections
are to be removed (for example, to handle the DC supply or the string fuses, for example), remove the
DC voltage by disconnecting all of the quick connectors (in P and P+ versions) or using a means of
disconnection outside the unit (versions S + S+).
4. Wait 5 minutes for the internal capacitances to discharge, the hot parts which may cause burns to cool
and the fan blades to stop turning.
5. Check that there is no voltage at the DC and AC inputs.
6. Signal cut-off point (Vac and Vdc) with a sign reading ¨Caution no switching...¨. If necessary, rope off the
work area.
