1.3 Installation and maintenance safety
1.3.1 General safety information
WARNING –BDo not do work on the photovoltaic generator, on the inverter, on its input or output cables, when the inverter is
connected to an electrical power system, or to the photovoltaic generator.
Before perform any maintenance operation on the inverter, follow this steps:
- Prepare the work: Carry out an on-site Risk Assessment or Job Hazard Analysis (Check for proper tools and PPE for the job;
Engage the person responsible for electrical equipment or system to review single-line, schematics, switching plans; Define the
appropriate work methods and initiate the permit to work process).
- Clearly identify the work location and equipments.
- Disconnect all sources and secure against reconnection by means of the “Lockout/Tagout” procedure to ensure
that any conductor cannot accidentally become live.
- Verify the absence of operating voltage (This must be carried out by means of a proper test instrument).
- Complete the permit to work and “Walk the Permit”.
WARNING –BRefer to “Inverter total de-energization” paragraph on this manual to know all detailed necessary steps to safely
operate on the inverter.
WARNING –BThe inverter front cover can be removed from authorized service personnel only (the users are not authorized to
remove inverter front cover).
FORBIDDEN –JDo not proceed with installation if the integrity of the equipment is compromised. Do not use the equipment if you
find any operating anomalies.
FORBIDDEN –JAvoid temporary repairs. All repairs should be carried out using only genuine spare parts, which must be installed
in accordance with their intended use.
FORBIDDEN –JThe labels affixed on the equipment must strictly NOT be removed, damaged, defaced, hidden, etc. The technical
data provided in this manual does not in any case replace that shown on the labels affixed on the equipment.
1.3.2 Environmental conditions and risks
ATTENTION –AThis device can be installed outdoors, but only in environmental conditions that do not prevent its regular operation.
These conditions are listed in the technical data and in the installation chapter.
ATTENTION –ADo not remove the connection boxes (AC and signals) of the inverter when it is raining, or when sand or dust can
blow into the unit. Infiltration of water or sand into the inverter can cause damage of the unit. It is of paramount importance to evaluate
the weather conditions in the risk assessment prior any intervention on the equipment. Any intervention on the inverter can be carried
out only in case of dry environment. Don’t proceed in case of rain (even light) or high humidity.
ATTENTION –AThis device is not designed to operate in environments that are particularly inflammable or explosive.
ATTENTION –AIn the event of fire, use CO2 extinguishers and auto-extraction systems to extinguish the fire in closed environments.
ATTENTION –AThe installer or maintenance technician must always pay attention to the work environment, ensuring that it is well-lit
and there are enough escape routes.
1.3.3 Electrical and thermal safety
WARNING –BObey these instructions to prevent injury or death or damage to the equipment. If you are not a qualified electrician,
do not perform any electrical installation or maintenance work.
WARNING –BObey all installation safety standards. This requires, among other things, the use of personal protection equipment
(PPE) such as arc-proof clothing, arc-proof masks, protective footwear, insulating and protective gloves, eye protection and hearing
protection. High power inverter installations have high fault currents.
WARNING –BBefore you operate on the inverter, isolate the AC line cables from the electrical power system with the AC disconnect
switch of the power system transformer (downstream of inverter). Also, isolate the inverter from the photovoltaic generator with the
DC disconnect switch of the generator or by other means (upstream of inverter). The internal AC disconnect switch (if present) do not
isolate the AC output cables and terminals of the inverter from the electrical power system. The internal DC disconnect switches (if
present) do not completely isolate the DC input cables or terminals from the DC voltage supplied by the photovoltaic generator. Refer
to “Inverter total de-energization” paragraph on this manual for further details.
WARNING –BDo not work on the communication and control signal cables when power is applied to the inverter or to the external
control circuits.
WARNING –BDo not perform insulation or voltage withstand tests on the inverter with exception for those indicated in this document.
WARNING –BFimer inverters must be earthed via the connection points marked with the protective earth symbol and using a
cable with an appropriate conductor cross-section for the maximum ground fault current that the generating system might experience.
HOT SURFACE –cWhen the device has just been switched off, it may have hot parts as a result of overheating of the heated internal
components (e.g.: transformers, accumulators, coils, etc.). Please pay attention to this.

1.4 Residual risks
ATTENTION –ADespite the warnings and safety systems, there are still some residual risks that cannot be eliminated.
These risks are listed in the following table with some suggestions to prevent them:
Risk analysis and description Suggested remedy
Noise pollution due to installation in unsuitable environments or
where individuals routinely work and/or animals dwell most of the
time.
Reassess the environment or the place of installation.
Adverse external weather conditions, water seepage, low
temperatures, high humidity, etc. Maintain ambient conditions suitable for the system.
Overheating of components (transformers, accumulators, coils,
etc. ) that could cause burns. Restricted cooling openings or
cooling systems of the equipment.
Use suitable PPE. Wait for the parts to cool down before opening
the inverter. Do not restrict cooling openings or cooling systems
of the equipment (e.g. heatsinks).
Inadequate cleaning that could compromises cooling and does
not allow the reading of safety labels. Clean the equipment, labels and work environment.
Stored energy in components that could generate hazardous
discharges.
Ensure that the components have discharged their energy before
working on them.
Inadequate training of staff. Ask for supplementary courses.
Installation of the equipment and/or mounting of the equipment
components temporarily incomplete.
Prevent unauthorized access to the installation area. Use a
sufficient number employees and PPE.
Accidental disconnections of the quick-fit connectors, with the
equipment in operation, may generate electrical arcs. Be careful about properly routing the DC inverter cables.
Mismatched brand of quick-fit connectors (if present) that may
void the warranty and could cause potential damage.
Use the same brand for the counterparts of the quick-fit connectors
installed on the inverter.
