3. Installation
3.2. Mounting solar modules on installation frame
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 deflection 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.
Attach the solar module using the predrilled mounting holes on the underside of
the frame (see Fig. 3–1). Use corrosion-resistant stainless steel bolts only.
I. Normal wind (up to 2400 Pa) and snow loads (up to 2400 Pa)
− Number of bolts to be used in each case on the long sides: 2
− Positioning of the screws: 1+4+5+8
II. High wind (up to 2400 Pa) and snow loads (up to 5400 Pa)
− Number of bolts to be used in each case on the long sides: 2
− Positioning of the screws: 1+4+5+8
The solar modules can be clamped in the provided clamping areas
(see Fig. 3–1).
I. Normal wind (up to 2400 Pa) and snow loads (up to 2400 Pa)
a. Clamping on the long side permitted? Yes

b. Clamping on the short side permitted? Yes
− Number of clamps to be used in each case on the short sides: 2
−
Positioning of the clamps on the short sides: N1+N2+N3+N4
II. High wind (up to 2400 Pa) and snow loads (up to 5400 Pa)
a. Clamping on the long side permitted? Yes
− Number of clamps to be used in each case on the long sides: 2
− Positioning of the clamps on the long sides: K1+K2+K3+K4
b. Clamping on the short side permitted? Yes
− Number of clamps to be used in each case on the short sides: 2
−
Positioning of the clamps on the short sides: N1+N2+N3+N4
Installation Manual
The clamping elements must not protrude past the edge of the frame on the
glass side. Make sure the clamping elements do not damage the frame surface
or bend the frame.

Electrical installation

3.3.1. Electrical values
All relevant electrical values are specified on the label 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 I
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.
Refer to Section 690-8 of the National Electrical Code for an additional
multiplying factor of 125 percent (80 percent derating) which may be applicable.
The maximum series fuse rating for these modules is: 15.0 A.

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.
3.3.3. Parallel and serial connection
Solar modules of the same type can be connected in parallel. These solar
modules are fundamentally designed for series connection.
Material damage due to connection errors.

and V
SC
Risk of electric shock. Risk of fire and injury from electric
arc.
Do not disconnect connections under load.
|
Ensure sufficient 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 heed the specified minimum bend radius.
Avoid large conductor loops.
|
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 specified maximum series
fuse rating of the solar modules.
