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.
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 time intervals specified by the inverter
manufacturer after switching off the inverter.

Ä
Never open the junction box.
Ä
Do not remove bypass diodes.
DANGER
! Risk of fatal injury due to electric shock!
Ä
Never touch live contacts with bare hands.
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.

Maximum allowed bend of the cable is with a
radius of 8 times the width of the cable.
Q CELLS standard cable is < 7.5 mm, resulting
in a maximum bend with a radius of 60 mm.
