Preparing the DC connections

Danger
Risk of death by electrocution!
• Observe the warning notes in Section 8.1, p. 57.
• Opposing Multi-Contact connectors must be attached to the DC cable to suit the Multi-Contact
MC4 DC connections (opposing contacts optionally available).
• All DC connections that are not connected to a cable must be closed off using the covers sup-
plied. This ensures that the inverter complies with the specified protection degree.
Notice
Danger of damage to the inverter and the modules.
• Connect the opposing contacts for the DC connections to the DC cable, observing the correct
polarity.
• The DC connections are internally interlinked to one MPP tracker. This means that external string
fuses (in their own casing) must be installed if the maximum possible reverse current of all strings
together is greater than the maximum permissible reverse current of the individual modules.
The string fuses and casings are not included in the delivery.
1. Attach the Multi-Contact MC4 opposing contacts to the DC cable according to the manufactur-
er's instructions.
2. If legally prescribed (e.g. France), plug in the optionally available safety sleeves, according to the
manufacturer's instructions (Fig. 10).
