4.2

Making the electrical connection

NOTE
Select conductor cross-section, safety type and safety value in accordance with the following basic condi-
tions:
Country-specific installation standards; power rating of the device; cable length; type of cable installation;
local temperature
NOTE
Due to the fact that the device is unable to limit the short circuit current from the grid in the event of a short
circuit, the AC-side fuse in the installation (on-site) provides protection against faults on the DC side.
For device safety, the max. prospective DC current is limited by the internal DC fuse in the event of an error.
Specification of the DC fuse (F1):
• 160Adc nominal current
• Nominal voltage (DC) > max. battery voltage
• Breaking capacity: 50kA
Use of e.g. Bussmann NH1gPV 160A (1000Vdc (Bussmann art. no.: PV-160ANH1)).
