8.4 Preparing the DC
Danger
Risk of death by electrocution!
• Opposing Multi-Contact connectors must be attached to the DC cable to suit the Multi-Contact
MC4 DC connections (opposing connectors optionally available).
• Observe the warning notes in Section 8.1, P. 64.
Notice
Danger of damage to the inverter and the modules.
Connect the opposing connectors for the DC connections to the DC cable, observing the correct
polarity.
1. Attach the Multi-Contact MC4 opposing connectors to the DC cable according to the manufac-
turer's instructions.
2. If legally prescribed (e.g. France), plug in the optionally available safety sleeves, according to the
manufacturer's instructions (Fig. 10).

Connecting the inverter and switching on the AC power

Danger
Risk of death by electrocution! Observe the warning notes in Section 8.1, P. 64.
1. If necessary, establish a data connection:
– Connect the inverter and bus master using the data connection cable.
– Manually switch on the termination (slide switch) at the last inverter on the bus.
2. Push the Multi-Contact MC4 opposing connector of the DC cable firmly into the DC connection
of the inverter until it audibly clicks into place.
3. Insert the AC plug into the socket on the inverter until it audibly clicks into place.
4. Switch on the AC line circuit breaker. The start page for initial commissioning is shown on the
display.
5. Perform initial commissioning and switch on the DC supply, as described in Sections 8.7 and 8.8.
