case replace that shown on the labels affixed on the equipment.
ATTENTION –ADo 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 verified a ‘safe working
area’ it is time to validate the ‘Permit to Work’ and “Walk the Permit”).
ATTENTION –ARefer to “Inverter total de-energization and safe access” paragraph on this
manual to know all detailed necessary steps to safely operate on the inverter.
1.3.2 Environmental conditions and risks
ATTENTION –AThe 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 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.
ATTENTION –AThe 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.

1.3.3 Electrical and thermal safety
ATTENTION –AObey 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.
ATTENTION –AObey 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.
ATTENTION –ABefore 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 and safe
access” paragraph on this manual for further details.
ATTENTION –ADo not work on the communication and control signal cables when power
is applied to the inverter or to the external control circuits.
ATTENTION –ADo not perform insulation or voltage withstand tests on the inverter.
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.
WARNING –BDo 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 flash incident occurs when the inverter front covers are open, the arc-flash proof
protection equipment might not provide sufficient protection for the operators.
HOT SURFACE –CWhen the device has just been switched off, 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.
1.3.4 Clothing and protection of personnel
NFPA - 70E, article 130.5 standard requires the equipment owner to field-label electrical equipment,
to protect both in-house and contract workers from electric shock and arc flash, with labels containing
the following information:
• Nominal system voltage
• Arc flash boundary
• At least one of the following information:
- Available incident energy and the corresponding working distance
- Arc flash PPE category in Table 130.7(C)(15)(a) or Table 130.7(C)(15)(b)
Label requirements are determined by site-specific arc flash studies and depend on the inverter
model, types and exact locations of external disconnects upstream and downstream of the inverter,
by voltages and power levels at any given installation.
NFPA 70E Article 130.3 states that the analysis must be reviewed at least every 5 years or whenever
a major modification occurs. This means that the label should include a date, and the date must be
documented.
The system is not ready for commissioning until PPE labels have been installed.
FORBIDDEN –HPersonnel must not wear clothes or accessories that could start fires
or generate electrostatic charges or, in general, clothing that can compromise personal
safety.
