Installation and Start-Up
NOTE
Be sure to use cables with a suffi ciently large cross-section 
to avoid excessive line impedance between the building’s 
distribution box and the respective blueplanet unit.
When the line impedance is high, i.e. long AC-side leads, 
the voltage at the line terminals of the inverter will increase 
as power is being fed in to the grid. The inverter measures 
this voltage. If the voltage at the grid terminals exceeds the 
line overvoltage limit, the inverter will switch off due to line 
overvoltage. This condition must be taken into consideration 
when wiring the AC and dimensioning the AC lead.
!
CAUTION
Check that the leads are properly connected.
ACTION
Once again, ensure that all connected leads are fi rmly 
 connected.
PV generator connection
The PV generator leads are connected to the bottom plate of 
the inverter.
