Safety instructions
General
Read these instructions carefully and com-
pletely until you have fully understood the
required safety measures and the individual
steps in the installation process.
Do not start installation work until the re-

are in place to implement the necessary
safety precautions.
Keep these instructions in a safe place.
Installation and initial operation
Solar modules should be installed and put
into operation by a specialist company only.
Maintenance and repair
Repairs to the system should only be carried
out by a specialist company.
Only use original replacement parts.

General safety instructions
For your own safety and that of your employees or
third parties and for the protection of the system you
are installing, please follow the safety instructions in
this section as well as those in Section 5. There may
be other hazards which arise in addition to the ones

Danger!
Do not disconnect, pull or open the coupler under
load!
Danger!
Use insulated tools only. Do not insert any metal ob-
jects into plug couplers!
Danger!
Do not touch any live electrical components!
Danger!
The solar module features a junction box without a
bypass diode. A permanent or regular shadowing ef-
fect must be avoided at all costs!
Warning!
Modules may become hot and their surfaces can
reach up to 90 °C!
Warning!
The voltages in modules increase when modules are
connected in series. A maximum of 10 modules may
be connected in series!
Warning!
Connecting modules in series leads to high system
voltages even under poor light conditions and may
damage modules and connected system components!
