• The following limiting values at the DC input of the inverter must not be exceeded:
5.4.2 Assembling the DC Connectors
For connection to the inverter, all connection cables of the PV modules must be equipped with the
DC connectors provided.
To assemble the DC connectors, proceed as follows. Ensure the connectors have the correct polarity.
The DC connectors have the symbols "+" and "‒".
Cable requirements:
• Use a PV1-F cable.
Procedure
1. Insert the stripped cable into the plug as far as
possible.
2. Press the clamping bracket down until it audibly
snaps into place.

DANGER!
Risk of lethal electric shock or fire
The maximum possible input current per string is limited by the connectors used. If the
connectors are overloaded, an electric arc may occur and there is a risk of fire.
• Ensure that the input current for each string does not exceed the maximum through-
fault current of the connectors used.
