MOIUNTING OPTIONS	REQUIREMENTS
All	The loads in the table are related to the mechanical stability of the

solar modules. The mechanical stability of the mounting system including clamps has to be evaluated by the system supplier. The listed test load values have been determined with the following clamp parameters: clamp width = 40 mm and clamp depth = 10 mm.

The system installer is responsible for the determination of location-specific load requirements. Ensure that the connection cables of the junction box do not run between laminate and mounting rails.

Modules bend under load. Therefore, sharp objects (e.g. screws, ballast stones, rail ends, rails with burrs or sharp corners) must not be placed near the module backside so as not to touch the laminate under load.

Ensure that the junction boxes do not touch the mounting structure (e.g. shorts rails, ballast, etc.) or the rooftop under load. Clamps or insertion profiles etc. must not touch the glass (even under load).

Unbalanced loads (e.g. snow overhangs, snowdrifts) which result in locally significantly increased loads must be removed or avoided by technical measures.

CL1a, CL2a, CL3, FB1, FB2| Ensure that module frame is fixed directly on the rail of the substructure (no spacer allowed between the module and substructure).
CL1a| With push test loads of 5400 Pa: The clamp position is variable in the given range but the distance between the clamps along the long side of the module (span) must not be larger than 1400 mm.
CL1b| Using of short mounting rails are permissible, if they overlap under the module less than 210 mm. Minimum clearance between frame bottom edge and roof top must be ≥ 35 mm.
CL1b, CL2b, CL3, FB2, CL6c, CL6d| A minimum support depth of 15 mm is required on the back side of the module.
CL5| The minimum required support depth on the module backside is 10 mm on long frame side and 15 mm on short frame side.
IP1| Ensure minimum support depth of 15 mm on the backside and 10 mm on the front side of the module.
FB1, FB2| Use M8 corrosion-proof screws and washers (diameter ≥ 15.8 mm) for mounting slots (Detail A, Fig.1). Mounting screws and washers should have the same material properties.
CL6c, CL6d| Use of short mounting rails under the modules are permissible, if they do not touch the laminate under load.

Electrical layout

Module Selection
For detailed key electrical data, please refer to the actual data sheet referring to the relevant Module (available at www.qcells.com).
For maximum energy yields, mismatches of specified electric current (IMPP) of more than 5 % should be avoided for all modules connected in series.

Safety Factor
During normal operation, a module may generate a greater current and / or higher voltage than that determined under standardized test conditions. Please use a safety factor of 1.25 for the following:

Calculating the voltage measurement values (VOC) of components
Calculating the current measurement values (ISC) of conductors
Sizing of control systems connected to the outlets of the solar modules
Please follow the valid national guidelines for the installation of electrical systems.

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

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 a single inverter or MPP tracker.
Layout with string fuses :
Use overcurrent devices (e.g. fuses) according to the relevant standards in each string. Use gPV-fuses according to IEC 60269-6. Observe the maximum permitted number of strings as indicated in the specifications 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.

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.
Do NOT unplug the cable when under load.
Do NOT connect any exposed cable ends.
Electrical work may only be performed by qualified and skilled personnel (see page 3).
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.
Please be aware of that the entire open circuit voltage is active even at low levels of solar irradiation.
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 safety extralowvoltage 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.
Be sure to observe the time intervals specified by the inverter manufacturer after switching off the inverter.
Make sure that the plugs can not be connected unintentionally.
Before working on the contacts, check them for safety extralow voltage.
