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.
Fire safety
•
Consult your local authority for guidelines and requirements for building or structural fire safety.
•
Roof constructions and installations may affect the fire safety of a building; improper installation may
create hazards in the event of a fire.
•
Use components such as ground fault circuit breakers and fuses as required by local authority.
•
Do not use panels near equipment or in places where flammable gases may be generated.
•
eArc have been rated Fire Class C, and are suitable for mounting on to a Class A roof.
Production Identification
Each eArc has two labels providing the following information:
•
Nameplate: describes the product type; rated power, rated current, rated voltage, open circuit voltage,
short circuit current, all as measured under standard test conditions; weight, dimensions etc.; the
maximum system voltage is 1000 volts.
•
Barcode: each individual eArc has a unique serial number. The serial number has 18 digits. The 1th to
4th digits are the module type for internal use, and the 5th and the 6th digits are the year code, and
the 7th and 8th digits are the month and the 9th and the 10th digits are the week code, and the 11th
and the 15th digits are order number, and the 16th and the 18th digits are the sequence codes. For
example, XXXX160417XXXXXXXX means the module was made in the 17th week of 2016. Each module
has only one bar code. It is permanently attached to the interior of eArc and is visible from the top front
of eArc. This bar code is inserted prior to lamination.
Mechanical Installation
Selecting the location
•
Select a suitable location for installing eArc.
•
eArc should face south in northern latitudes and north in southern latitudes.
•
For detailed information on the best installation angle, refer to standard solar photovoltaic installation
guides or consult a reputable solar installer or systems integrator.
•
eArc should not be shaded at any time. If an eArc is shaded or even partially shaded, it will fail to
