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.

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 to maximise generation.
•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
perform at ideal conditions and result in lower power output.
•Do not use eArc near equipment or in locations where flammable gases may be generated or collected.
General installation
•eArc mounting structure must be made of durable, corrosion-resistant and UV-resistant material.
•Always observe the instructions and safety precautions included with eArc support frames.
•Do not drill additional mounting holes in the PV panel’s ribs as this will void the warranty.
•Before installing eArc on a roof, always ensure the roof construction is suitable. In addition, any roof
penetration required to mount eArc must be properly sealed to prevent leaks.
•Dust building up on the surface of eArc can impair with eArc performance. SUNMAN recommends
installing eArc with a tilt angle of at least 10 degrees, making it easier for dust to be washed off by rain.
•Always keep the back sheet of the panel free from foreign objects, “plants and vegetation”, or structural
elements, which could come into contact with the panel, especially when the panel is under mechanical
load.
•Ensure panels are not subject to wind or snow loads exceeding the maximum permissible loads, and
are not subject to excessive forces due to the thermal expansion of the support structures: Refer to the
following installation methods for more detailed information.
eArc product design loads
•All eArcTM product have been evaluated for test loads of 2400 Pa with the following solutions.

▶Overview
The Sunman SMD Series use quick and easy installation method which is called “Quick-bonding”. Quick
bonding allows you to install a Sunman SMD module directly to an approved metal surface using an
approved structural grade silicone. Quick bonding can be direct to the roof or on Aluminium 6065-T5
raining, such as the product from Unistrut. Please ensure the surface is clean, free of dust and debris,
before application as this may inhibit adhesion.
Please note: Please contact Sunman to complete Installation training before
attempting your first installation.

d. Clean the color steel roofing
•To ensure silicone achieves sufficient bond, the roof must be thoroughly cleaned, free of dirt, debris
and metal powder. If you are unsure of the state of the roof, please contact Sunman for assistance.
•Clean off excess dirt and debris off the roof sheet with rags and water. Leave to dry. If it is extremely
dirty, pressure cleaning with water is recommended.
•If using Tonsan 1527, clean the roof with isopropyl alcohol and wait to dry.
•If using Sika SG-20, apply the Sika Aktivator-205 on to clean cloth. Wiping down the roof, apply to the
adhesion area. Reapply until clean. Leave to dry.
e. Install chemical bonding material
•Consult and strictly adhere to installation requirements specified in the Sunman engineering
certificates
•Do not install apply silicone to roof while moisture is present
•Apply the silicon with the nozzle perpendicular to the roof. The length of the chemical bonding material
shall span the full length of the contact interface, i.e. if the panel is installed in landscape, the silicone
bead shall span the full width of panel and if the panel is installed in portrait, the silicone bead shall
span the full length of panel
•Do not let a “skin” form over the silicone. This will directly impede the final curing strength. To manage
this, only apply enough silicone to the roof for one module at a time. See note from Sika installation
manual below on how to check for the presence of a “skin” over the silicone:
