particular attention to cleanliness during ins
-
tallation. The use of lubricants is not permitted.
Always protect unplugged connectors against
soiling of any type during transport, storage,
and during installation, as the connectors only
satisfy the requirements for their protection ca-
tegory when plugged in. It is forbidden to open
the junction box or modify or remove the cable
or frame.
The minimum bend radius for the connection
cable is 60 mm. The cables must be laid so
that mechanical strain on the conductors and
connections is ruled out. Take into account
the product-specific length of the connection
cable specified in the relevant data sheets at
www.solarwatt.com.
The plug contacts must not be connected or disconnected under load. Failure to comply
with this warning could result in DEATH!
WARNING
Potential equalization of the solar generator is
prepared in the factory and is recommended. It
can be carried out using the existing grounding
bores on the long sides of the frame (see figure)
or suitable clamps with integrated grounding
pins in accordance with the valid local regula
-
tions.

It is advisable to install lightening protection in exposed locations. The solar modules
should be incorporated in existing lightening protection equipment. For this, take into
account the relevant valid regulations (e.g. EN 62305 and VDE 100).
NOTE
Maintenance and servicing
A photovoltaic system needs practically no
maintenance, as the solar modules are cleaned
by the rain at the recommended minimum angle
of 15°. To avoid reductions in yield, we do, ho-
wever, recommend carrying out a regular visual
check on the module surfaces. Particularly hea-
vy soiling (e.g., leaves) can cause shades which
reduce performance and should therefore be
removed. Clean the glass surface with softened
water, a water-ethanol- or water-isopropanol
intermixture and a soft nonabrasive cloth only.
In exceptional cases, a conventional cleaning
agent may also be used in the recommended
dose. Do not use aggressive cleaning agents or
metal objects, as they can be particularly dama-
ging to the hardened glass surface. The electric
cables should (where accessible) be checked
regularly for damage, corrosion, and firm hold.
Pay particular attention to DGUV regulation 3
and DIN VDE 0105-100.
