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.
Do NOT unplug the cable when under load.
Do NOT connect any exposed cable ends.
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.
Please be aware of that the entire open circuit voltage is active
even at low levels of solar irradiation.
Please follow the valid national regulations and safety guide-
lines for the installation of electrical devices and systems.
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.
Carry out work on the inverter and the wiring with extreme cau-
tion.
Ensure that the modules are disconnected at the inverter prior
to separation.
Be sure to observe the time intervals specified by the inverter
manufacturer after switching off the inverter.
Make sure that the plugs can not be connected unintentionally.
Before working on the contacts, check them for safety ex-
tra-low voltage.
Danger! Risk of fatal injury due to electric shock!
Only use dry, insulated tools for electrical work.
Danger! Risk of fatal injury due to electric shock!
Never open the junction box.
Do not remove bypass diodes.
Danger! Risk of fatal injury due to electric shock!
Never touch live contacts with bare hands.
Cover connectors by suitable protective caps until
installation.
Danger! Risk of fatal injury due to electric shock!
Insulate any exposed cable ends.
Only connect cables with plugs.

4.2 Electrical installation safety
Danger! Risk of fatal injury due to electric shock!
Be sure to maintain the time intervals as specified by
the inverter manufacturer between switching off the
inverter and beginning any further work.
Danger! Risk of fatal injury due to electric shock!
Never plug or unplug the cable when under load.
Modules must not carry any current.
1. Switch off the inverter.
OFF
EN
2. Switch off the DC circuit breaker.
3. Measure shutdown in DC String.
(no DC current flow).
4. Disconnect plugs by the use of appropriate
and qualified tools of the manufacturer.
5. When connecting the modules proceed in reverse
order.
Danger! Risk of fatal injury due to electric shock!
Electrical work may only be performed by qualified
and skilled personnel (see page 3).
Ensure correct polarity.
