Overview
•
CAN only to be used on Solar-Log 1000 and 2000 (CAN interface).
•
Integrated interface
•
Where to connect: CAN socket on the outside of the bottom of the inverter.
•
Only use ready-made cable sets.
Two different special cable sets must be ordered separately.
- Prefabricated cable set between the Solar-Log 1000 and 2000 and the first inverter, includ-
ing cable termination.
- Ready-made cable set with 5 pin Phoenix contact connection plug for connecting the invert-
ers to each other.
The number of cables are required depends on the number of inverters.
Maximum total cable length: 200 m

Installation steps
• Switch off the inverters and Solar-Log™
• Connect inverters to the Solar-Log™
• Connect the inverters to each other
Connect the inverters to the Solar-Log 1000 and 2000�
Connection is only done using a ready-made data cable, specially for connecting to the Solar-Log
1000 and 2000 (optional extra; not supplied).
Procedure
1. Insert the CAN plug into the inverter CAN IN socket.
2. If only one inverter is to be connected this must be terminated.
Insert the two 5 pin 120 Ω terminal resistors from the ready-made cable set into the CAN OUT
socket.
3. Insert the terminal block connector into the Solar-Log 1000 and 2000 CAN socket.
