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.
