ELECTRICAL CONNECTION

4.1 SAFETY

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 Electrical work may only be performed by qualified and
skilled personnel (see page 3).
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 safety
extra-low voltage range is exceeded.
Ä Carry out work on the inverter and the wiring with extreme
caution.
Ensure that the modules are disconnected at the inverter
Ä
prior to separation.
Ä Be sure to observe the time intervals specified by the inverter
manufacturer after switching off the inverter.
Ä Make sure that the plugs can not be connected unintentionally.
Ä Before working on the contacts, check them for safety extra-low
voltage.
Danger! Risk of fatal injury due to electric
shock!
Ä Only use dry, insulated tools for electrical
work.
