Electrical layout
•
Never physically disconnect the plugs when the module is under load, since this creates electric arcs
and could result in life-threatening injuries.
•
Exercise the utmost caution when working with the inverter and the cables.
•
Ensure that the modules on the inverter are activated before being disconnected.
•
Once the inverter has been switched off, before beginning further work, make sure to uphold the
time intervals prescribed by the manufacturer in order to allow the high-voltage components to
unload.
•
Cover solar modules with opaque material during the assembly process. This is the only way to
make sure that the modules are reliably de-energized.
•
Never touch the live contacts with bare hands. Only use isolated, dry tools for installation.
•
During connection, ensure the correct polarity. The connectors are marked with a plus sign on the
positive terminal and a minus sign on the negative terminal.
•
Do not under any circumstances open the splash-proof junction box.
•
Only install undamaged solar modules.
•
Ensure prior to installation that the junction box, cable, connectors and tools are dry and free of
damage.
•
Always store the solar modules in a secure, dry place. The packaging is not weather-resistant.
•
Ensure that even at low temperatures and/or solar radiation of over 1000 W/m², the maximum
open-circuit voltage of the wired modules does not exceed the system voltage of 1000 VC (IEC
61646/IEC 61730 or IEC 61215) or 600 V DC (UL1703).
•
Integrate the solar plant into the existing lightning protection system in accordance with local
regulations.
•
Do not perform installation or maintenance work on the modules under conditions of heavy wind or
rain. We recommend that you only perform installation or maintenance work during dry weather.
•
When mounting the modules on buildings, there is a risk of tools, mounting materials or solar
modules falling down and hurting people. Because of this, block off the danger zone on the
ground prior to beginning mounting work.
•
Warn people who are near the danger zone or inside the building. Keep children away from the
installation site.
•
Carry out wiring work in such a way that no people are endangered and no damage can occur.
•
Protect all parts of the module from mechanical stress (such as pressure, tension or torsional
stress) during transport and installation. Ensure that the bend radius for cables at the output of the
junction box is kept at 60 mm as a minimum during installation or operation.
WARNING!
Danger of death due to electric shock!
WARNING!
Damaged module components may be hazardous!
