Connection in a 3-Phase System
• In a 3-phase system, always connect the master to phase L1, slave 1 to phase L2
and slave 2 to phase L3. This circuitry results in a right rotating field.
• The system does not monitor additional fuses. Check any additional fuses regularly!
NOTICE!
The components in the Sunny Island (e.g., communications interface) can be
damaged by an electrostatic discharge!
• When working on the Sunny Island and when handling the components observe all
ESD safety regulations.
• Eliminate static charge by touching the grounded metal casing.
• Only then should you begin any work.
