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. Connect the DC cables to the inverter with the
correct polarity. Push the Multi-contact MC4 DC
plug into the socket on 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; see Fig. on the
