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 and safe access”
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.
WARNING – B Do not switch-on the inverter with the front covers open, even during
troubleshooting. The inverter front covers act as arc flash hazard protection. If a 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 – 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.
