If you connect a signal generator for generators without autostart function, connect the signal
generator as follows:
Requirements:
☐ The technical requirements of the multi-function relay must be met (see Section 12"Technical
Data",page144).
☐ Conductor cross-section: 0.2 mm² ... 2.5 mm²
1. Connect the signal generator 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.
6.21 Connecting GenMan to the Off-Grid Inverter
Generators that are controlled using GenMan have two control contacts: one contact for the starter
and one contact for ignition or pre-heating.
Figure20: Connection of the GenMan to the off-grid inverter
If you have installed a GenMan, connect it as follows:
Connecting GenMan in a cluster
Slaves control the GenMan less reliably than masters do.
• Connect the GenMan only to the master.
• In a multicluster system, always connect the GenMan to the master of the main cluster.
