2. About Safety
2.1 Important Safety Instructions
The HMS-1600C-4T/HMS-1800C-4T/HMS-2000C-4T microinverter is designed and tested according to in-
ternational safety requirements. However, certain safety precautions must be taken when installing and
operating this inverter. The installer must read and follow all instructions, cautions and warnings in this
installation manual.
•
All operations including transportation, installation, start-up and maintenance must be carried out
by qualified, trained personnel.
•
Check the product before installation to make sure there is no damage caused during transporta-
tion because such damage can compromise the insulation integrity and safety clearances. Choose
installation location carefully and adhere to specified cooling requirements. Unauthorized removal
of necessary protections, improper use, incorrect installation and operation may cause damage to
the equipment or incur serious safety and shock hazards.
•
You should get the necessary approvals from the local power operator before connecting the mi-
croinverter to the power grid. This connection must be made only by qualified technical personnel.
It is the responsibility of the installer to provide external disconnect switches and Over Current
Protection Devices (OCPD).
•
Each input of the inverter is connected to one PV module. Do not connect batteries or other
sources of power supply. The inverter can be used only if all the technical parameters are observed
and applied.
•
Do not install the equipment in flammable, explosive, corrosive, extremely hot/cold, and humid en
-
vironment. Do not use the equipment when safety devices in these environments are not working.
•
Personal protective equipment such as gloves and goggles must be used during installation.
•
Inform the manufacturer about non-standard installation conditions.
•
Do not use the equipment if any operating anomalies are found.
•
All repairs must be done with qualified spare parts which must be installed in accordance with their
intended use and by a licensed contractor or authorized Hoymiles service representative.
•
Liabilities arising from components that are not produced by Hoymiles are on the part of their re-
spective manufacturers.
•
Whenever the inverter has been disconnected from the public grid, please be extremely careful
as some components can retain a charge sufficient to create a shock hazard. Before touching any
part of the inverter, please ensure the surface and the whole equipment are within the limit of safe
temperature and voltage potential.
•
Hoymiles is not liable for any damage caused by incorrect or improper operation.
•
Electrical installation and maintenance shall be conducted by a licensed electrician and shall comply
with local wiring rules.
