ABQ2026IQE01_A - Installation and Operation Manual
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 inverters 3 and 4
(slaves):
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 2, connect the pre-installed cable 2-4 on connector 2.b.
4. On inverter 3, disconnect the fiber optics cable 1-3 from connector 3.e.
5. On inverter 3, connect the pre-installed cable 2-3 on connector 3.e.
6. On inverter 4, disconnect the fiber optics cable 1-4 from connector 4.e.
7. On inverter 4, connect the pre-installed cable 2-4 on connector 4.e.
8. Configure the synchronization switch of inverter 2 as master by activating the switch.
