Maintenance - SolarWorld Sunmodule Plus SW mono series Benutzerinformation

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.)!
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.
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.
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.
Grounding in the US and Canada
The modules can be connected at the module corner to the ground using a lay-in
lug. We recommend using the components as listed below. Any grounding method
and components listed according to NEC requirements are also acceptable in the US
and Canada.

Underwriters Laboratories Information (U.S. and Canada)
For the electrical ratings please refer to the datasheet. 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 compliance 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 pre-
sented below and the requirements of the National Electrical 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 instruc-
tions. Common hardware items such as nuts, bolts, star washers, 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 mechanical connections and hol-
ding electrical grounding devices in the proper position for electrical conductivity.
Such devices, where supplied with the module and evaluated through the require-
ments in UL 1703, may be used for grounding connections in accordance with the
instructions provided with the module. The electrical characteristics are within ±10
percent of the indicated values of ISC, VOC, and Pmax under standard test conditions
(irradiance of 100 mW/cm², AM 1.5 spectrum, and a cell temperature 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 690-8 shall be follo-
wed to address these increased outputs. In installations not under the requirements
of the NEC, 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 ampa-
cities, overcurrent device ratings, and size of controls connected to the PV output.
To reduce the operating temperature the module has to be mounted on any sur-
face 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
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 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 automoti-
ve (vehicles) purposes. The module must not be exposed to extraordinary chemi-
cal 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 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 modules connected in
series, only modules of the same amperage rating may be used together. For modu-
les connected in parallel, modules with the same voltage ranges must be used tog-
ether. The modules must not be operated at a higher voltage than the permissible
system voltage. The inside opening of 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
adversely 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. Fixing the module on its narrow sides
only is not sufficient. In regards to "Top-Down" mounting methods, the maximum
clamping pressure is 50 N/mm² (7250 psi). Do not drill any holes into the module. Use
corrosion-proof fixing material.
electrical connection
Tightening torque
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-
25 Ibf-in, 8 AWG str
ditions. Make sure to avoid gaps in a plugged connection. Only singlecore solar cables
20 Ibf-in, 10-14 AWG sol/str
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
62 Ibf-in (7.0 Nm)
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.
Cleaning
In generel, 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 deionized water) without any cleaning
agents. If necessary, a soft cleaning device (sponge.g. soft brush with split bristles)
may 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.
