5. Connect the wires to the Relay1 or Relay2 terminals using the 3-pole terminal
(torque: 0.5 Nm ... 0.6 Nm):
6.19 Connecting Control Cables for Autostart Generators
Autostart generators are started and stopped by a contact.
Figure18: Connection of generator control to the off-grid inverter
If you are using an autostart generator, connect the control as follows:
1. Connect the control to the multi-function relay (see Section 6.18"Assignment of Multi-Function
Relay",page54). Use the C and NO terminals.
2. Enter the function of the multi-function relay used in the configuration table
(see Section 7.10.1"Use of the Multi-Function Relays",page90). Note the AutoGn value.
Connection Explanation
NC In energy-saving mode closed.
C Change-over contact
NO In energy-saving mode open.
Generator control in a cluster
Slaves control the generator less reliably than masters do.
• Connect the generator control only to the master.
• If the off-grid system is a multicluster system, always connect the generator control to the
master of the main cluster.
