Option – external synchronization
For special applications it might be necessary to tap the synchronization before the power
commutating choke, e.g.
- when operating via field triggering circuit
- in case of an instable power supply

The wiring has to be short-circuit proof or protected means of a line protection.
Connection across the terminals X18:35, 36, 37
Observe the phase position!
- L3 across X10:14 (via power choke) and directly across terminal X18:36
- L2 across X10:15 (via power choke) and directly across terminal X18:37
- L1 across X10:16 (via power choke) and directly across terminal X18:35
Attention:
If incorrectly connected at X18 – the device can be destroyed
