Installation safety
•Never open electrical connections or unplug connectors while the circuit is under load.
•Contact with electrically charged parts of the panels, such as terminals, can result in burns, sparks and
lethal shock whether or not the panel is connected.
•Do not touch eArc unnecessarily during installation. The front surface and the ribs may be hot; there is
a risk of burns and electric shock.
•Do not work in the rain, snow or in windy conditions.
•Avoid exposing cables to direct sunlight in order to prevent insulation degradation.
•Keep children well away from the system while transporting and installing mechanical and electrical
components.
•Completely cover eArc with an opaque material during installation to prevent electricity from being
generated.
•Do not wear metallic rings, watchbands, earrings, nose rings, lip rings or other metallic objects while
installing or troubleshooting photovoltaic systems.
•Use only insulated tools that are approved for working on electrical installation.
•Follow the safety regulations for all other system components, including wires and cables, connectors,
charging regulators, inverters, storage batteries, rechargeable batteries, etc.
•Under normal conditions, a photovoltaic eArc is likely to experience conditions that produce more
current and/or voltage than reported at standard test conditions. Accordingly, the values of Isc and Voc
marked on this eArc should be multiplied by a factor of 1.25 when determining component voltage
ratings, conductor current ratings, fuse sizes, and size of controls connected to the PV output.
•Only use same or connectable connectors to connect eArc to form a string, or connect to another device.
Removing the connectors will void the warranty.
