NOTES
NOTE 1 - It is the responsibility of the operator/owner of the EVCSs to perform the necessary maintenance routines as recommended by the equipment specialist or manufacturer to ensure the safe use of the EVCS and any potential hazard due to lack of maintenance.
NOTE 2 - Fault reporting procedure
If any EV charging station or charging point is found to be unsafe or unsuitable for operation, the following steps shall be taken:
a) The supply to the equipment shall be switched off;
b) The means of isolation shall be off and locked to prevent re-connection of supply;
c) A clear label notifying users that the equipment is out of service shall be displayed prominently;
d) The operator/owner shall be informed immediately
