Synchronization of three inverters
In this section we indicate the diagram to perform the synchronization of three inverters. Wire according to the
diagram using the fiber optics cables provided by Ingeteam.
Ingeteam provides one additional fiber optics cable with the aim of making the synchronization system redundant.
Ingeteam recommends the pre-installation of said wiring, without performing a connection. When confronting an
incident of an inverter configured as master, you can reconfigure the system selecting another inverter as master in
a three inverter synchronization system

If the master inverter has the incident (in the aforementioned diagram marked as 1) perform the following steps to
reconfigure the system to establish inverter 2 as master and maintaining the synchronization with inverter 3 (slave):
1. On inverter 2, disconnect the fiber optics cable 1-2 from connector 2.e.
2. On inverter 2, connect the pre-installed cable 2-3 on connector 2.a.
3. On inverter 3, disconnect the fiber optics cable 1-3 from connector 3.e.
4. On inverter 3, connect the pre-installed cable 2-3 on connector 3.e.
5. Configure the synchronization switch of inverter 2 as master by activating the switch.
Synchronization of four inverters
In this section we indicate the diagram to perform the synchronization of four inverters. Wire according to the
diagram using the fiber optics cables provided by Ingeteam.
