9.3.7 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.
