DANGER! Life danger due to electric shock!
When disconnecting a DC circuit, electric arcs can occur that can result in dangerous injuries.
•
Carry out work on the inverter and the electrical cables with extreme caution.
•
Never pull the plug when under load.
•
Ensure that the modules are disconnected at the inverter prior to disconnection from one
another.
• Be absolutely certain to observe the time intervals specified by the manufacturer after
switching off the inverter and prior to starting subsequent work such that the high voltage
components can be discharged.
•
Cover the module for the duration of the assembly with opaque material. Only then is the
module reliably de-energized.
•
Never touch live contacts with your bare hands. Use only insulated, dry tools for the instal-
lation.
•
Pay attention to the correct polarity when connecting. The connectors are labelled with plus
for the plus terminal and minus for the minus terminal.
•
Do not open the junction box under any circumstances. The bypass diode must not be
removed.
Observe the following when selecting and using electrical cables and connectors:
•
Only use pre-packaged electrical cables and insulated, identical connectors.
•
Ensure that all electrical components are in a proper, dry and safe condition. In this way
you avoid that electrical short-circuits or dangerous contact voltages occur due to defective
or damaged cables.
•
Always avoid the mechanical stressing of the electrical cables.
•
Ensure a tight connection between the individual connectors (especially to the inverter).
Make sure they click together properly.
Upon completion of the installation, ensure that:
•
the wiring lays not open or is hanging loosely, and is protected from dirt and moisture.
•
the plug connections do not lie on a water-channeling surface and are properly connected.
•
all necessary safety and functional tests have been carried out according to the current
state of technology.
DANGER!
Life danger due to electric shock! Damaged module components may cause risk of fire
hazard!
•
Please do not attempt to correct problems on your own!
•
In case of problems or damaged modules (for example, glass breakage, damaged cables)
please contact your installer immediately. The installer must ensure that the module is
removed from the system as soon as possible.
