For detailed key electrical data, please refer to the actual data sheet referring to the relevant Module (available at

www.q-cells.com).

Ä Only connect modules of the same type and the same

power class.

Safety Factor

) of

Series Connection

Connection of modules in series is only permitted up to the maximum system voltage as listed in the applicable data sheet of all the relevant modules to be installed.

Take into account all possible operating situations and all relevant technical norms and regulations when designing the system. It has to be ensured that the maximum system voltage, including all necessary safety margins, is not exceeded.

Take the voltage limit of the inverter into account when determining the maximum number of modules in the string.

Parallel Connection

Modules may be damaged by the occurrence of reverse currents (caused by module defects, ground leaks, or

defective insulation).

Ensure that the maximum reverse current load capacity

indicated in the data sheet is met. In order to limit reverse currents that may occur, we recommend using the following safety options:

1) Layout with a limited number of parallel connected

strings :

Without undertaking further current blocking measures, a maximum of two module strings may be operated in parallel on an inverter or MPP tracker.

2) Layout with string fuses :

place fuses for each string of modules at the plus and minus ends. Observe the maximum permitted number

of strings as indicated in the specications provided by

the respective string fuse manufacturer and the technical guidelines.

NOTE!

When installing different product versions, the lowest minimum permitted reverse current load capacity applies.

Inverters

Inverters with or without transformers may be used.

Ä Ensure that all personnel are aware of

and adhere to accident-prevention and safety regulations.

Ä While working wear clean gloves.

Ä Inspect the packaging for damages. Ä Contact the transport company regarding

any damage to the packaging.

Ä Follow any instructions on the packaging.

DANGER! Risk of fatal injury due to electric shock!

When disconnecting an electric circuit carrying direct current, electric arcs can occur that may result in life-threatening injuries.

Ä Do NOT unplug the cable when under load. Ä Do NOT connect any exposed cable ends. Ä Do NOT touch the poles at the same time.

A solar module generates electrical current and voltage even at a low intensity of illumination. Sparks and electric arcs may result from the separation of a closed circuit. These can result in life-threatening injuries. The danger increases when several modules are connected in series.

Ä Please be aware of that the entire open circuit voltage

is active even at low levels of solar irradiation.

Ä Please follow the valid national regulations and safety

guidelines for the installation of electrical devices and systems.

Please make sure to take all necessary safety precautions. With module or phase voltages of more than 120 V, the extra-low voltage range is exceeded.

Carry out work on the inverter and the wiring with extreme caution.

Ensure that the modules are disconnected at the inverter prior to separation.

Ä Be sure to observe the specied time intervals after

switching off the inverter. High-voltage components need time to discharge.

DANGER! Risk of fatal injury due to electric

Ä Never open the junction box. Ä Change of bypass diodes is only allowed

by qualied and trained personnel in

8 MAINTENANCE AND CLEANING

Q CELLS solar modules are known for a long operating life and minimal maintenance effort and expense. Dirt and grime are usually washed away by rain. If the module is fully or partially shaded by dirt or debris (e.g., plants,

bird droppings), it needs to be cleaned to prevent a loss

of performance.

Maintenance

The system should be inspected by an installer annually to check the following:

•

all system components sit securely and are corrosion free.

•

the connection is secure and all electrical components are clean and undamaged.

Cleaning

WARNING! Risk of injury due to hot and live modules!

Ä Only clean modules that have cooled down. Ä Do not carry or wear any electrically conductive parts.

NOTE! Module damage may occur!

Ä Do not clean modules with water if there

is a risk of frost.

0°

Ä Remove dirt with lukewarm water or

alcohol based glass cleaner, a broom, or a soft cloth.

Ä Do not use tensides, scrapers, or any

high-pressure water cleaning equipment.

WARNING! Risk of falling due to unsecured access!

Ä Never access the installation area alone or without

taking adequate security precautions.

Ä Please commission a trade specialist.

Clean the modules as follows:

NOTE! Module surface damage may occur!

Ä Remove snow and ice carefully without force (e.g. with

a very soft broom).

Ä Do not scratch off dirt. Ä

Rinse dirt (dust, leaves, etc.) off with lukewarm water or

use an alcohol based glass cleaner. Do not use abrasive detergents or tensides.

Ä Use a soft cellulose cloth (kitchen roll) or sponge to

carefully wipe off stubborn dirt. Do not use micro eece

wool or cotton cloths.

Isopropyl alcohol (IPA) can be used selectively to remove

stubborn dirt and stains within one hour after emergence.

Ä Please follow the safety guidelines provided by the IPA

manufacturer.

Ä Do not let IPA run down between the module and the

frame or into the module edges.

Ä Free the substructure from any dirt and

debris (leaves, bird nests, etc.).
