DANGER!
Risk of fatal injury due to electric shock!
When disconnecting an electric circuit carrying direct
current, electric arcs can occur that may result in
life-threatening injuries.
Ä Do NOT unplug the cable when under load.
Ä Do NOT connect any exposed cable ends.
Ä Do NOT touch the poles at the same time.
A solar module generates electrical current and voltage
even at a low intensity of illumination. Sparks and electric
arcs may result from the separation of a closed circuit.
These can result in life-threatening injuries. The danger
increases when several modules are connected in series.
Ä Please be aware of that the entire open circuit voltage
is active even at low levels of solar irradiation.
Ä Please follow the valid national regulations and safety
guidelines for the installation of electrical devices and
systems.
Ä Please make sure to take all necessary safety precautions.
With module or phase voltages of more than 120 V, the
extra-low voltage range is exceeded.
Ä Carry out work on the inverter and the wiring with extreme
caution.
Ä Ensure that the modules are disconnected at the inverter
prior to separation.
Ä Be sure to observe the specified time intervals after
switching off the inverter. High-voltage components
need time to discharge.
DANGER
! Risk of fatal injury due to electric
shock!
Ä Never open the junction box.
Ä Change of bypass diodes is only allowed
by qualified and trained personnel in
disconnected and covered state.
DANGER
! Risk of fatal injury due to electric
shock!
Ä Never touch live contacts with bare
hands.
Ä
Do not touch the poles at the same
time.
Ä Cover connectors by suitable protective
caps until installation.
DANGER
! Risk of fatal injury due to electric
shock!
Ä Insulate any exposed cable ends.
Ä Only connect cables with plugs.
DANGER
! Risk of fatal injury due to electric
shock!
Ä Only use dry, insulated tools for electrical
work.

Option 2:
Ä
Install the module at the 4 mounting
points, see Fig. 3, p. 7.
Ä Tighten clamps according to
manufacturer’s instructions.
NOTE
! Module damage may occur!
Ä Do not subject modules to mechanical
tension. Max. torsion 10 mm/m.
Option 3:
Ä
Install the module using mounting
profiles, Fig. 3, p. 7.
Option 1:
Ä
Fasten the module with 4 clamps
in the specified clamping range,
see Fig. 3, p. 7.
Ä Tighten clamps according to
manufacturer’s instructions.
