Thermal hazard
WARNING: removal of guards or covers is allowed only 10 minutes after
the voltage has been removed; ; this is to let components cool down and
allow any electrostatic charges and parasitic voltages to be discharged.
When the equipment has just been switched, it may have hot parts, as a
result of overheating of the surfaces at temperature (e.g.: transformers,
accumulators, coils, etc.) so be careful where you touch.
In the event of re, use CO
2
extinguishers and use auto extraction systems to ght re in
closed environments.
Clothing and protective devices for staff
ABB has eliminated sharp edges and corners, but in some cases it is not
possible to do anything, and we therefore advise wearing the clothing
and personal protective devices provided by the employer.
Staff must not wear clothes or accessories that can start res or generate electrostatic char-
ges or, in gener, clothing that can impede personal safety.
All operations on the equipment should be performed with suitably insu-
lated clothes and instruments.
E.g.: Insulated gloves (class 0, category RC)
Maintenance operations must be carried out with the equipment discon-
nected from the grid and from the photovoltaic generator.
Staff must NOT go near the equipment with bare feet or wet hands.
The maintenance technician must in any case make sure no one else
can switch on or operate the equipment during the maintenance opera-
tions, and must report any anomaly or damage due to wear or ageing so
that the correct safety conditions can be restored.
The installer or maintenance technician must always pay attention to the
work environment, so that it is well lit and has sufcient spaces to ensure
they have an escape route.
In the installation, consider or make sure the noise emitted based on the
environment is not such that it exceeds thresholds allowed by law (less
than 80 dBA).
