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. In the USA, refer to Section 690-8 of the National
Electrical Code (NEC) for an additional multiplying factor of 125 percent (80 percent de-rating)
which may be applicable.
Contact with a DC voltage of 30 V or more is potentially hazardous. Exercise caution when wiring
or handling modules exposed to sunlight.
Only connect modules with the same rated output current in series. If modules are connected in
series, the total voltage is equal to the sum of the individual module voltages.
Only connect modules or series combinations of modules with the same voltage in parallel. If
modules are connected in parallel, the total current is equal to the sum of individual module or
series combination currents.
Always use the same type of module within a particular photovoltaic system.
With a serial interconnection of the modules, the sum of the open circuit voltage at Standard
Test Conditions (Voc @ STC) must not pass over the maximal system voltage indicated, both
indicated in the modules datasheet.
If the sum of short circuit currents of the parallel connected modules passes over the reverse
current (indicated in the table of chapter 8), string diodes or fuses have to be used in each string
of modules connected in parallel. These string diodes or fuses have to be qualified for the
maximum expected current and voltage. Maximum rating for series fuse has to be 15 A and diode
12 A.
Observe the instructions and safety precautions for all other components used in the system,
including wiring and cables, connectors, DC-breakers, inverters, etc.
Use appropriate safety equipment (insulated tools, dielectric gloves and shoes, etc) approved for
use on electrical installations.
3.3. General prescriptions for installation
Do not apply paint or adhesive to the modules.
Do not use mirrors or other hardware to artificially concentrate sunlight on the module.
When installing modules, observe all applicable local, regional and national codes and
regulations. Obtain a building and/or electrical permit where required.
Keep children well away from the system while transporting and installing mechanical and
electrical components.
Do not wear metallic rings, watchbands, ear, nose, or lip rings or other metallic devices while
installing or troubleshooting photovoltaic systems.
Do not drill holes in the glass surface of the module. Doing so will destroy the module and void
the warranty.
Do not drill additional mounting holes in the module frame. Doing so will void the warranty.
Do not lift the module by grasping the module's junction box or electrical leads.
Do not apply paint or adhesive to the module.
Do not stand or step on module. Danger of breaking the glass or slipping off with possibility of
severe injury or death!
Do not drop the module or allow objects to fall on the module.
Do not place any heavy objects on the module.
Inappropriate transportation and installation may damage the module glass or the solar cells
inside the module.
If module frame is with film, remove it before installation.
