General safety
eArc that fall under this application class may be used in system operation at more than 50V DC or
240W, where general contact access is anticipated. eArc are qualified for safety under IEC 61730-2 and within this application class are considered to meet the requirements for Safety Class II.
eArc are qualified for Application Class A(IEC 61730-1).
Installing solar photovoltaic systems requires specialized skills and knowledge. Installation should only
be performed by qualified personnel.
Installers should assume all risks of injury that might occur during installation, including, but not limited
to, the risk of electric shock.
One single eArc may generate more than 30V DC when exposed to direct sunlight. Contact with a DC
voltage of 30V or more is potentially hazardous.
Do not disconnect during load connection.
Photovoltaic solar eArc convert light energy to direct current electrical energy. They are designed for
outdoor use. eArc can be ground mounted, mounted on rooftops, vehicles or boats. The proper design of support structures lies within the responsibility of the system designers and installers.
Do not use mirrors or other magnifiers to concentrate sunlight onto eArc.
When installing the system, abide to all local, regional and national statutory regulations. Obtain a
building permit if necessary.
eArc electrical characteristics are within ±10% of the indicated values of Isc, Voc and Pmax under
standard test conditions (Irradiance of 1000W/m², AM 1.5 spectrum, a cell temperature of 25 ).
Only use equipment, connectors, wiring and support frames suitable for solar electrical systems.
Always use fall protection equipment when working from heights of 6 feet 183cmor above”.
Follow Occupational Safety and Health Act (OSHA) or local governing safety regulations regarding fall protection. (UL only)
Handling safety
Do not lift eArc by grasping eArc junction box or electrical leads.
Do not stand, step or walk on any side of eArc.
Do not drop eArc or allow objects to fall on eArc.
Do not place any heavy objects on eArc.
Be cautious when placing eArc down onto a surface, particularly when placing it in a corner.
Inappropriate transport and installation may break eArc and void the warranty.
Do not attempt to disassemble eArc, and do not remove any attached nameplates or components from
eArc.

Do not apply paint or adhesive to eArc top surface.
To avoid damage to the front cover and backsheet, do not scratch, dent or hit the front cover and
backsheet.
Do not drill holes in the ribs of SMA series. This may compromise the frame strength, cause corrosion
of the ribs and void the warranty.
Do not scratch the anodized coating of the ribs (except for grounding connection). It may cause
corrosion of the ribs or compromise the ribs strength.
A panel with broken front plate or torn back sheet cannot be repaired and must not be used since
contact with any panel surface or the ribs can cause an electric shock.
Work only under dry conditions, and use only dry tools. Do not handle panels under wet conditions
unless wearing appropriate protective equipment.
When storing uninstalled panels outdoors for any period of time, always cover the panels and ensure
that the front cover faces down “on a soft flat surface to prevent water from collecting inside the panel and causing damage to exposed connectors.
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
