Electric shock The connection of several modules in series creates increased voltage and may impose danger. Do not insert electrically conducting parts into connectors! Do not install 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 installed by the manufacturer. Do not apply paint or adhesives on the back side. Do not work on modules 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 to prevent falls. Secure work materials against dropping. Ensure a safe working environment so as to prevent accidents. Fire prevention/explosion prevention 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 regulations 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 installed by the manufacturer. Do not apply paint or adhesives on the back side. Do not work on modules with sharp objects

Unpacking and intermediate storage Do not use the junction box as a handle. Do not place modules roughly on hard surfaces 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. Do not work on modules with sharp objects. Store modules in a dry place. Leave modules in original packaging until ready to install.

Assembly ▹ Recommended angle of inclination for photovoltaic operated stand-alone systems/year-round use. Latitude Fixed angle of inclination 0° – 15° 15° 15° – 25° equal to the latitude 25° – 30° Latitude + 5° 30° – 35° Latitude + 10° 35° – 40° Latitude + 15° over 40° Latitude + 20° Your local photovoltaic dealer can give you information about a suitable installation location and method. Grounding of the 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 system against direct lightning stroke. Local standards shall be observed.

Grounding in the US and Canada Grounding hardware can be installed utilizing a lay-in lug, bolt with serrated washer, washer and nut. The lug must be a tin-coated copper lug, silver in color. Do NOT use a bare copper lug, which is brown. Any grounding method and components listed according to NEC requirements are also acceptable in the US and Canada[/vc_column_text][/vc_column][vc_column width=”1/2″][vc_column_text]Specific Information (U.S. and Canada) The solar module electrical characteristics are within +/-10% of the module label indicated values of Isc , Voc and Pmpp 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. 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 National 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. Intended wire to be used: Listed PV Wire, AWG 12, outer diameter 7.1±0.2mm, rated min. 90°C dry/wet, 600V. PV Connectors: Type PV-KBT4/6II-UR and type PV-KST4/6II-UR are suitable for the output cable. Cable conduits should be used in locations where the wiring is accessible to children or small animals. Modification or tampering of diodes by unqualified personnel is not permitted. Please consult a SolarWorld Service Center for additional information regarding diode replacement/repair. To reduce the operating temperature the module must be mounted with a minimum standoff height of 4 in (10 cm) above any surface. 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 or 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) 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 ft/1 m to ventilation openings shall be ensured. Appropriate usage 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 mounting elements or other sharp objects (e.g. cable ties on mounting sections must not be mounted near the module back side. When wiring in series, use only modules of the same amperage rating, when wiring in parallel, use only modules of the same voltage. The modules must not be operated at a higher voltage than the permissible system voltage. For system documentation, please note the model and serial number. 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 shade free area. Even partial shading results in yield losses and should be avoided. Proper ventilation of the module underside will prevent heat build-up that reduces performance. Artificially concentrated sunlight shall not be directed on the module. Mounting The modules must be securely installed at a minimum of 4 locations on the frame. Mounting is only allowed in designated areas. These designated areas for mounting 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. Mounting the module on its narrow sides is not sufficient. In regards to “Top-Down” mounting methods, the maximum clamping pressure is 50 N/mm² (72.5 psi). Do not drill any holes into the module. Use corrosion-proof mounting material. For more details see mounting drawings and details shown on the last page. Recommendation: Sunfix supporting profile, Sunfix (end) clamp 1.22/1.44 in (31/34 mm), frame tightening torque: 177 in-lb (20 Nm) Electrical connection Use only rated copper solar wire and appropriate connectors. Ensure that they are in perfect electrical and mechanical condition. Connectors may only be connected under dry conditions. Make sure to avoid loose connections in a plugged connection. Only singlecore solar wires may be used for connecting the modules. Wires should be attached to the installation system by means of UV-resistant cable ties. Exposed wires should be protected against sunlight and damage by suitable precautions (e.g. conduits). Check that wiring polarity is correct prior to commissioning the system.

Cleaning On principle, the modules do not need much cleaning if the tilt angle is sufficient (> 15°; self-cleaning by rain). If soiling occurs, we recommend cleaning 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.
