Total de-energization procedure

1. Preliminary control:
Make sure that the unit must be turned on.
2. Identification of AC external main source:
Clearly identified the external AC main breaker with the plant manager cooperation and, if necessary, by
functionality test of it.
3. Operate the main AC external source isolation and secure:
Turn off the external AC main breaker and carry out a LOTO.
4. Functionality check:
Check that the charger is shut down.
5. Operate the main AC external breaker:
Turn off the external AC main breaker.
6. Main Voltage absence check:
Check the absence of voltage below the main breaker of the EVSE, using the dedicated holes (A).
The verification must be carried out through the dedicated holes (A) in the Main AC protection barriers (41),
using the voltage detector by checking between phases to ground and respectively between them.
