A External diameter 10 to 16 mm
B Conductor cross-section 4 to 6 mm²
C Stripping length of the insulated conductors approx. 13 mm
D Stripping length of the outer sheath of AC cable approx. 53 mm
The PE conductor must be 8mm longer than the L and N conductors
Larger cross-sections should be used for longer cables.
Cable design
The conductor cross-section should be dimensioned to avoid power loss in cables
exceeding 1% of rated output power.
The higher grid impedance of the AC cable makes it easier to disconnect from the grid
due to excessive voltage at the feed-in point.
The maximum cable lengths depend on the conductor cross-section as follows:

4 mm² 28m 23m 20m 17m
6 mm² 42 m 35m 30m 26m
The required conductor cross-section depends on the inverter rating, ambient
temperature, routing method, cable type, cable losses, applicable installation
requirements of the country of installation, etc.
Residual current protection
The product is equipped with an integrated universal current-sensitive residual current
monitoring unit inside. The inverter will disconnect immediately from the mains power
as soon as fault current with a value exceeding the limit.
If an external residual-current device is required, install a residual-current
device which trips at a residual current of 100 mA or higher.
Overvoltage category
The inverter can be used in grids of overvoltage category III or lower in accordance with
IEC 60664-1. This means that it can be permanently connected at the grid-connection
