General safety
•eArche™ 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. eArche™ are qualified for safety under IEC 61730-2
and within this application class are considered to meet the requirements for Safety Class II.
•eArche™ 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 eArche™ may generate more than 15V 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 eArche™ convert light energy to direct current electrical energy. They are designed
for outdoor use. eArche™ 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 eArche™.
•When installing the system, abide to all local, regional and national statutory regulations. Obtain a
building permit if necessary.
•eArche™ 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.

Handling safety
•Do not lift eArche™ by grasping eArche™ junction box or electrical leads.
•Do not stand, step or walk on any side of eArche™.
•Do not drop eArche™ or allow objects to fall on eArche™.
•Do not place any heavy objects on eArche™.
•Be cautious when placing eArche™ down onto a surface, particularly when placing it in a corner.
•Inappropriate transport and installation may break eArche™ and void the warranty.
•Do not attempt to disassemble eArche™, and do not remove any attached nameplates or components
from eArche™.
•Do not apply paint or adhesive to eArche™ top surface.
•To avoid damage to the back sheet, do not scratch, “dent” or hit the back sheet.
•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 glass 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 eArche™ unnecessarily during installation. The front surface 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 eArche™ 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 eArche™ 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 eArche™ 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 eArche™ 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.
•eArche™ have been rated Fire Class C, and are suitable for mounting on to a Class A application.

Production Identification
Each eArche™ 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 600 volts.
•Barcode: each individual eArche™ 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 eArche™ and is visible from the top
front of eArche™. This bar code is inserted prior to lamination.

Mechanical Installation
Selecting the location
•Select a suitable location for installing eArche™.
•For detailed information on the best installation angle, refer to standard solar photovoltaic installation
guides or consult a reputable solar installer or systems integrator.
•eArche™ should not be shaded at any time. If an eArche™ is shaded or even partially shaded, it will fail
to perform at ideal conditions and result in lower power output.
•Do not use eArche™ near equipment or in locations where flammable gases may be generated or
collected.
General installation
•eArche™ mounting structure must be made of durable, corrosion-resistant and UV-resistant material.
•Always observe the instructions and safety precautions included with eArche™ support frames.
•Do not drill holes in the composite material PV panel as this will void the warranty. The panel frame has
allowance for drilling holes for installation.
•Before installing eArche™ on a roof, always ensure the roof construction is suitable. In addition, any
roof penetration required to mount eArche™ must be properly sealed to prevent leaks.
•Dust building up on the surface of eArche™ can impair with eArche™ performance. Sunman
recommends installing eArche™ 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.

screwing the panel frame onto the rail using Teks screw.
Take note of the “Aluminium rail layout”details to take note of the number of rails and number of Tek
screws needed.
Teks screw is also used to create a conductive connection between the rails and panel frames for
earthing.
Key Products
The Mounting-Rail method uses 4 primary materials;
1. Rails
2. Teks screws
3. Roofing screws

The Mounting-Rail installation is a step by step process;
1. Place the aluminum rails on the roof across the purlins. Mark out the screw points on the rails. Ensure
that the rails are in parallel and the ends of the rail will line up when a panel in installed perpendicular.
The screw points on the rails shall be in line with the purlins on the roof. The screw points on the roof
shall be on the peak of the roof materials. Screw the rails onto the purlins using the roofing screws;
