DANGER!
Electric shock
The connection of two or more modules in series results in the accumulation of
voltage and imposes danger. Do not insert electrically conductive parts into con-
nectors! Do not attach 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.)!
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
to the module, nor work on it with sharp objects.
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 roof covering rated for the application.
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 top of each other. Do not step or stand
on modules. Do not place any objects on modules. 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.
through the requirements in UL 1703, may be used for grounding connections in
accordance with the instructions provided with the module. The electrical charac-
teristics are within ±10 percent of the indicated values of ISC, VOC, and Pmax under
standard test conditions (irradiance of 1000 W/m², AM 1.5 spectrum, and a cell tem-
perature of 25°C (77°F)). Under normal conditions, a photovoltaic module is likely to
experience conditions that produce more current and/or voltage than reported at
standard test conditions. The requirements of the National Electrical Code (NEC) in
Article 690 section II shall be followed to address these increased outputs. 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
Artificially concentrated sunlight shall not be directed on the module or panel. The
module must neither be immersed in water nor be exposed to continuous spraying
(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 automoti-
ve (vehicles, trailers, etc.) purposes. The module must not be exposed to extraordi-
nary 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 openings shall be ensu-
red; 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. When using a string inverter,
for modules connected in series, only modules of the same amperage rating may be
used together. For modules connected in parallel, modules with the same voltage
ranges must be used together. The modules must not be operated at a higher volta-
ge than the permissible system voltage. The frame corner element is intended for
water drainage and must not be blocked. 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 adver-
sely affecting performance.
Mounting
The modules must be securely fixed at a minimum of 4 locations on the substructu-
re. Fixing is only allowed in designated areas. When using “Top-Down” clamps use
high-quality extruded aluminum or stainless steel clamps or stamped stainless steel
clamps. Insure that the mounting system and clamps meet the design requirements
of the system. In regards to “Top-Down” mounting methods, the maximum clam-
ping pressure is 50 N/mm² (15 ft-lb).
Do not use formed (bent) clamps! Do not drill any holes into the module. Use corro-
sion-proof fixing material.
For bottom-mounting hardware use 8 to 9mm (1/4" or 5/16") diameter bolts that are
less than 25 mm (1") in length. The head of the bolt must face the module backsheet.
Torque specifications are set by the system engineer.
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 solar cables with an
adequate cross-section (2.5 mm² or 14 AWG minimum) and appropriate connectors
may be used for connecting the modules. Cables should be attached to the installa-
tion system by means of UV-resistant cable ties. Exposed cables should be protected
against sunlight and damage by suitable precautions. Check that wiring is correct
(polarity!) prior to starting the inverter.
SolarWorld Sunmodules are equipped with Amphenol UTX H4 connectors; connect
ONLY Amphenol Helios H4 or Amphenol UTX H4 connectors with the module.
Cleaning
In general, the modules do not need any cleaning if the tilt angle is sufficient
(> 15°; self-cleaning by rain). In case of heavy soiling, we recommend cleaning the
modules with plenty of water (tap water or deionized water) without any cleaning
agents. If necessary, a soft cleaning device (e. g. sponge, soft brush with split bristles)
maybe be used. In case of soiling by dust or sand the modules can be cleaned with a
soft brush without using water. 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.

General Information
This module is rated for use in application class A according to IEC 61730. For the elec-
trical ratings please refer to the datasheet. Under normal conditions, 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 current ratings, fuse sizes, and size of controls
connected to the PV output.
Specific Information (U.S. and Canada)
The fire rating of this module is valid only when mounted in the manner specified
in the mechanical mounting instructions. The module is considered to be in comp-
liance with UL 1703 only when the module is mounted in the manner specified by the
mounting instructions below. A module with exposed conductive parts is considered
to be in compliance with UL 1703 only when it is electrically grounded in accordance
with the instructions presented below and the requirements of the National Electri-
cal Code. Where common grounding hardware (nuts, bolts, star washers, spilt-ring
lock washers, flat washers and the like) is used to attach a listed grounding/bonding
device, the attachment must be made in conformance with the grounding device
manufacturer’s instructions. Common hardware items such as nuts, bolts, star was-
hers, lock washers and the like have not been evaluated for electrical conductivity
or for use as grounding devices and should be used only for maintaining mechani-
cal connections and holding electrical grounding devices in the proper position for
electrical conductivity. Such devices, where supplied with the module and evaluated
