1.3 Installation and maintenance safety
1.3.1 General safety information
WARNING –
B
Do 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 – B Refer to “Inverter total de-energization” paragraph on this manual to know all detailed necessary steps to safely
operate on the inverter.
WARNING –
B
The inverter front cover can be removed from authorized service personnel only (the users are not authorized to
remove inverter front cover).
FORBIDDEN –
J
Do not proceed with installation if the integrity of the equipment is compromised. Do not use the equipment if you
find any operating anomalies.
FORBIDDEN –
J
Avoid temporary repairs. All repairs should be carried out using only genuine spare parts, which must be installed
in accordance with their intended use.
FORBIDDEN – J The 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 – A This 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 –
A Do 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 –
A
This device is not designed to operate in environments that are particularly inflammable or explosive.
ATTENTION –
A
In the event of fire, use CO2 extinguishers and auto-extraction systems to extinguish the fire in closed environments.
ATTENTION –
A
The 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 –
B
Obey 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 –
B
Obey 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 –
B
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 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 –
B
Do not work on the communication and control signal cables when power is applied to the inverter or to the external
control circuits.
WARNING – B Do not perform insulation or voltage withstand tests on the inverter with exception for those indicated in this document.
WARNING –
B
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.
HOT SURFACE – c When 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.
