Installation Manual

4
· The solar modules can be mounted both vertically and
horizontally. Respect the range of clamping.
· You can nd further installation instructions in the
installation manual for the respective installation system.
· The mounting system must be made from material that is
resistant to corrosion and atmospheric conditions and able
to withstand the loads required.
· Installation of cable has to follow the best demonstrated
available technology. Avoid abrasion of wire insulation
caused by e.g. wind. Do not lay cable on sharp edges.
Respect minimum required bend radius.
3.2 Mounting solar modules on installation system
The solar modules can be damaged if the proper
procedure is not followed
Secure the solar modules against slipping and falling.
· Do not drop the solar modules.
· Do not hold the solar module by its socket or connection
cables.
· Always grasp the solar modules simultaneously at two
opposite points on the module frame when lifting.
Never carry solar modules by just one part of the frame.
· Do not expose the solar modules to mechanical impact.
· Do not touch the solar modules with sharp or pointed
objects.
· To prevent lasting marks on the glass, only touch the
solar modules with clean, soft and silicone-free protective
gloves. Do not wear leather or powdered gloves.
· Make sure the rear of the mounted solar module is not
damaged even in the case of deection due to mechanical
stress (e.g. due to snow loads).
· Do not drop any objects on the solar module and do not
step on it.
· The clamping elements must not protrude past the edge of
the frame on the glass side.
· Use corrosion-resistant stainless steel bolts only.
· Make sure the clamping elements do not damage the
frame surface or bend the frame.
3.3 Electrical installation
3.3.1 Electrical values
All relevant electrical values are specied on the sticker on
the reverse of the solar module.
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 current ratings, fuse
sizes, and size of controls connected to the PV output.
The modules are qualied for application class A: Hazardous
voltage (IEC 61730: higher than 50V DC; EN 61730: higher
than 120V), hazardous power applications (higher than
240W) where general contact access is anticipated (Modules
qualied for safety through EN IEC 61730-1 and -2 within this
application class are considered to meet the requirements for
Safety Class II.
The reverse current loadability of the solar modules is 20
Ampere.
3.3.2 General safety instructions
· Carry out the cabling in accordance with the applicable
regulations.
· Make sure that the cables and connections are not
damaged. Protect the cables from damage.
Risk of electric shock.
Risk of re and injury from electric arc.
· Do not disconnect connectors under load.
· Ensure sucient protection against contact with live parts.
· Only use insulated tools.
· Do not insert any electrically conducting parts into the
connectors.
· Never open the junction box.
· Make sure there is no tension in the cable when positioning
and follow the specied minimum bend radius.
· Avoid large conductor loops.
3.3.3 Parallel and serial connection
Solar modules of the same type can be connected in parallel.
The solar modules in this series are fundamentally designed
for series connection.
· Only use solar modules of the same type and output
for parallel connection. Take measures for overcurrent
protection (e.g. line fuse) if necessary. Never exceed the
specied reverse current loadability of the solar modules.
Maximum number of module strings that are allowed to
be switched in parallel: 2 (fuse rating / (short-circuit
current * 1.25) + 1)
· Make sure that only solar modules with the same amperage
(Impp) are interconnected for series connection and make
sure that the voltages of lines connected in parallel are
the same. Even at low temperatures, never exceed the
maximum permissible system voltage of the solar modules.
Maximum number of modules that are allowed to be
switched in series: maximum system voltage / (open circuit
voltage * 1.25), with respect to the temperature coecient.
· Make sure that the number and connection of the solar
modules match the electrical values specied by the
devices connected to the photovoltaic system.
· Make sure that the polarity is correct.
