DaNGer!
electric shock
The connection of several modules in series results in the adding up of voltage
and imposes danger. Do not insert electrically conducting parts into connectors!
Do not fit solar modules and wiring with wet connectors! Make sure to work
with dry tools and under dry working conditions!
Work on live parts
When working on wiring, use and wear protective equipment (insulated tools,
insulated gloves, etc.)!
WarNING!
arcing
Modules generate direct current (DC) when exposed to light. When breaking a
closed circuit, a dangerous arc may be generated. Do not cut any live wires.
Safe installation
Do not carry out installation work in strong winds. Secure yourself and other
persons against falling. Secure work materials against dropping. Ensure a safe
working environment so as to prevent accidents.
fire protection/explosion protection
Modules must not be installed in the vicinity of highly flammable gases, vapors
or dusts (e.g. filling stations, gas tanks, paint spraying equipment). The safety
instructions for other system components must also be followed. Make sure to
comply with local standards, building regulations and accident prevention regu-
lations during installation. For roof installation, modules must be mounted on a
fire-resistant base material.
aTTeNTION
Do not use damaged modules. Do not dismantle modules Do not remove any
parts or nameplates fitted by the manufacturer. Do not apply paint or adhesives
on the back side, nor work on it with sharp objects.
Unpacking and intermediate storage
Do not use the junction box as a handle. Do not place modules roughly on hard floor
or on their corners. Do not place modules on to of each other. Do not step or stand on
modules. Do not place any objects on modules. Do not work on modules with sharp
objects; store modules in a dry place.
Grounding of module and frame
We recommend ensuring the functional grounding of the module metal frame. If
an exterior lightning protection system is already provided, the PV system has to be
integrated into the protection concept against direct lightning stroke. Local stan-
dards shall be observed.
Grounding in the US and Canada
The modules can be connected to the grounding holes using a lay-in lug and a sok-
ket head cap screw. We recommend using the components as listed below. Any PV
grounding method and components complying with the NEC are also acceptable in
the US and Canada.

Underwriters Laboratories Information (U.S. and Canada)
The solar module electrical characteristics are within +/-10% of the module label indi-
cated values of Isc , Voc and Pmpp under Standard Test Conditions (irradiance of 100
mW/cm , AM 1.5 spectrum, and a cell temperature of 25°C/77°F). Under normal con-
2
ditions, a photovoltaic module 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 module should be multiplied by a factor of 1.25
when determining component voltage ratings, conductor capacities, fuse sizes, and
size of controls connected to the PV output. Refer to section 690-8 of the Natio-
nal Electric Code (NEC) for an additional multiplying factor of 125% (80% de-rating)
which may be applicable. Over-current protection shall be in accordance with the
requirements of Article 240 of the NEC. Conductor recommendations: 8-14 AWG
(1.5-10 mm2) USE-2 (nonconduit)/ THWN-2 (conduit ), 90°C wet rated. Cable conduits
should be used in locations where the wiring is accessible to children or small ani-
mals. Modification or tampering of diodes by unqualified personnel is not permit-
ted. Please consult a SolarWorld Service Center for additional information regarding
diode replacement/repair.
To reduce the operating temperature the module has to be mounted on any surface
with a minimum distance of 4 inches (10 cm).
In Canada the installation shall be in accordance with CSA C22.1, Safety Standard for
Electrical Installations, Canadian Electrical Code, Part 1.
Suitable ambient conditions
The module is intended for use in moderate climatic conditions. The module must
not be exposed to focused light. The module must neither be immersed in water
nor be exposed to continuous wetting (e.g. by fountains). Exposure to salt or sulfur
(sulfur sources, volcanoes) implies a risk of corrosion. The module must not be used
for maritime (e.g. boats) or automotive (vehicles) purposes. The module must not be
exposed to extraordinary chemical loads (e.g. emissions from manufacturing plants).
If the modules are installed on stables, a distance of 3.28 ft (1 m) to ventilation ope-
nings shall be ensured; apart from this, the modules shall not be used as a direct roof
panel on stables.
appropriate installation situation
Make sure that the module meets the technical requirements of the overall system.
Other system components should not exert any adverse mechanical or electrical
influences on the module. Modules may bend under high loads. For this reason,
sharp-edged fixing elements or other sharp objects (e.g. cable ties on mounting sec-
tions must not be mounted near the module back side. For connection in series, only
modules of the same amperage rating, for connection in parallel, only modules of
the same voltage ranging may be used. The modules must not be operated at a hig-
her voltage than the permissible system voltage. The inside opening of the frame
corner element is intended for water drainage and must not be closed. For system
documentation, please note the serial numbers.
Optimum installation
In order to avoid performance losses, all modules connected in series should be
arranged with the same orientation and tilt angle. The modules should be installed
in an all-season shadow-free area. Even partial shadowing results in yield losses
and is to be avoided. Ventilation of the module back side will prevent heat build-up
adversely affecting performance.
Mounting
The modules must be securely fixed at a minimum of 4 locations on the substruc-
ture. Fixing is only allowed in designated areas. These designated areas for fixing
are located on the module long sides. They are located between 1/8 of the module
length and 1/4 of the module length, measured from the module corner. Fixing the
module on its narrow sides is not sufficient. As regards clamping the modules from
the front, the clamping area on the module frame must be at least 130 mm² for each
fixing point. The required clamping force is 100 N/mm². Do not drill any holes into the
module. Use corrosion-proof fixing material.
electrical connection
The modules are provided with factory-assembled cables and connectors . Do not
open the junction box in any case. Connectors may only be connected under dry con-
ditions. Make sure to avoid gaps in a plugged connection. Only singlecore solar cables
with an adequate cross-section (4 mm² minimum) and appropriate connectors may
be used for connecting the modules. Cables should be attached to the installation
system by means of UV-resistant cable ties. Exposed cables should be protected
against sunlight and damage by suitable precautions (e.g. conduits) In order to limit
voltages released by indirect lightning shock, the area of all conductor loops must
be reduced to a minimum. Check that wiring is correct (polarity!) prior to starting
the generator.
Tightening torque
Cleaning
35 Ibf-in, 4-6 AWG str
On principle, the modules do not need any cleaning if the tilt angle is sufficient
25 Ibf-in, 8 AWG str
(> 15°; self-cleaning by rain). In case of heavy contamination, we recommend cleaning
20 Ibf-in, 10-14 AWG sol/str
the modules with plenty of water (hose) without the addition of cleaning agents but
application of a soft cleaning device (sponge). Never scrape or rub off dirt; this may

result in micro-scratches.

Maintenance

We recommend regular inspections of the system to ensure that:
1. All fixtures are securely tightened and corrosion-free;
2. Wiring is securely connected, properly arranged and free of corrosion;
3. Cables are free of damage;
Please also observe applicable standards.
