WARNING: the removal of guards or covers is only permitted after the
voltage has been removed and time period indicated on the label has
passed. This is to let the components cool down and allow the internal
capacitors to discharge. Refer to "Inverter switch-off" chapter on this ma-

When the device has just been switched off, it may have hot parts as a
result of overheating of the heated surfaces (e.g.: transformers, accumu-
lators, coils, etc.) so be careful where you touch.
In the event of fire, use CO2 extinguishers and auto-extraction systems to extinguish the fire
in closed environments.
C
lothing and protection of personnel
ABB has done its best to eliminate sharp edges and corners, but as this
is not always possible you are advised always to wear the clothing and
personal protective equipment provided by the employer.
Personnel must not wear clothes or accessories that could start fires or generate electrostatic
charges or, in general, clothing that can compromise personal safety.
All operations on the equipment must be performed with adequately in-
sulated clothing and instruments.
E.g.: insulating gloves, class 0, RC category
Maintenance operations may only be performed after the equipment has
been disconnected from the grid and from the photovoltaic generator.
Refer to "Inverter switch-off" chapter on this manual to know all the ne-
cessary step to safely operate on the inverter.
Staff must NOT go near the equipment with bare feet or wet hands.
The maintenance technician must in any case ensure that no one else
can switch on or operate the device during the maintenance operations,
and should report any anomaly or damage due to wear or ageing so that
the correct safety conditions can be restored. Refer to "Inverter switch-
off" chapter on this manual to know all the necessary step to safely ope-
rate on the inverter.
The installer or maintenance technician must always pay attention to the
work environment, ensuring that it is well-lit and there is enough room to
ensure an escape route.
During installation, consider that the noise emitted based on the envi-
ronment could possibly exceed the legal thresholds (less than 80 dBA),
therefore, suitable ear protection must be worn.
