Maintenance, configuration modifications and management operations require the involvement of all

must be carried out in observance of health
and safety regulations.
The Standards and Laws governing this aspect vary depending on the personnel involved, methods of
access and/or the tasks which may be carried out on the product and envisage constructive measures aimed
at guaranteeing adequate levels of safety.

This standard and its national equivalents must therefore be adhered to whenever it is necessary to access
a PV system.
