DANGER! Life danger due to electric shock and fire!
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 disconnect 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 energised 
components can be discharged.

• Cover the module for the duration of the assembly with opaque material. Only then is the 

module reliably de-energised.

• 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 positive terminal and minus for the negative terminal.

• Ensure that the open circuit voltage of the modules don‘t exceed the maximum permitted 

system voltage of 1000 VDC. 

• 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 solar cables and insulated, compatible connectors. Q.SMART modules uses MC4 

connectors.

• Only use additional components which are compatible with the modules and its electrical 

specifications.

• Ensure that all electrical components are in a undamaged, dry and safe condition. In this 

way you avoid that electrical short-circuits or dangerous contact voltages occur due to de-
fective 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 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 (e.g. 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.
