Installation and maintenance safety
General safety information
Do not proceed with installation if the integrity of the equipment is compromised. Do not use
the equipment if you nd any operating anomalies.
Avoid temporary repairs. All repairs should be carried out using only genuine spare parts,
which must be installed in accordance with their intended use.
The labels axed on the equipment must strictly NOT be removed, damaged, defaced, hid-
den, etc.
Do not do work on the photovoltaic generator, or the inverter, or its input or output cables, when
the inverter is connected to an electrical power system, or to the photovoltaic generator.
Before performing any maintenance operation on the inverter, follow this steps:
• Prepare the work: Do 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; Decide on the appropriate work
methods and initiate the permit to work process).
• Clearly identify the work location and equipment.
• Disconnect all sources and Secure against reconnection by means of a ‘Lockout/
Tagout procedure to ensure it cannot accidentally become live.
• Verify the absence of operating voltage (This must be by means of a proper test instrument).
• Complete the permit to work and “Walk the Permit” (Now we have veried a ‘safe working
area’ it is time to validate the ‘Permit to Work’ and “Walk the Permit”).
Refer to “Inverter total de-energization and safe access” chapter on this manual to
know all detailed necessary steps to safely operate on the inverter.
Environmental conditions and risks
The 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.
Do not open the front covers of the inverter when it is raining, or when sand or dust can blow
into the unit. Water or sand in the inverter can cause damage in the unit. In the risk assessment
prior any intervention on the equipment it is of paramount importance to evaluate the weather
conditions. Any intervention on the inverter can be done only in case of dry environment. Don’t
proceed in case of rain (even light) or high humidity.
The device is not designed to operate in environments that are particularly inammable or
explosive.
In the event of re, use CO2 extinguishers and auto-extraction systems to extinguish the re
in closed environments.
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.

1 - Safety and accident prevention
Electrical and thermal safety
WARNING! Obey these instructions to prevent injury or death, or damage to the
equipment. If you are not a qualied electrician, do not perform any electrical installation
or maintenance work.
Obey all installation safety standards. This can require, 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.
Before 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 the inverter). Also,
isolate the inverter from the photovoltaic generator with the DC disconnect switch of the generator
or by other means (upstream the 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 complete isolate the DC input cables or
terminals from the DC voltage supplied by the photovoltaic generator. Refer to “Inverter total
de-energization and safe access” chapter on this manual for further details.
Do not work on the communication and control signal cables when power is applied to the
inverter or to the external control circuits.
Do not perform insulation or voltage withstand tests on the inverter.
FIMER 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.
Do not switch-on the inverter with the front covers open, even during troubleshooting. The
inverter front covers act as arc hazard protection. If a highly unlikely arc ash incident occurs
when the inverter front covers are open, the arc-ash proof protection equipment might not
provide sucient protection for the operators.
When the device has just been switched o, it may have hot parts as a result of overheating
of the heated surfaces (e.g.: transformers, accumulators, coils, etc.) so be careful where you
touch.

Residual risks
Despite 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.
Table of residual risks
RISK ANALYSIS AND DESCRIPTION SUGGESTED REMEDY
Noise pollution due to installation in unsuitable environments or where
sta󰀨 work permanently.
Reassess the environment or the
place of installation.
Suitable local ventilation that does not cause overheating of the
equipment and is su󰀩cient not to create discomfort to people in the
room.
Restore suitable ambient
conditions and air the room.
External weather conditions, such as water seepage, low temperatures,
high humidity, etc.
Maintain ambient conditions
suitable for the system.
Overheating of surfaces at temperature (transformers, accumulators,
coils, etc. ) can cause burns. Also be careful not to block the cooling slits
or systems of the equipment.
Use suitable protective equipment
or wait for the parts to cool down
before switching on the equipment.
Inadequate cleaning: compromises cooling and does not allow the safe-
ty labels to be read.
Clean the equipment, labels and
work environment adequately.
Accumulation of electrostatic energy can generate hazardous dischar-
ges.
Ensure the devices have
discharged their energy before
working on them.
During installation, temporarily mounting the equipment or its components
may be risky.
Be careful about and disallow
access to the installation area.
