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 afxed 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 veried 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 inammable 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.
