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.
