Single phase applications
There is not a separate archive file for single-phase applications. Use standard ail archives.
Recommended wirings
Generator (and mains) single-phase voltage has to be connected to all three-voltage terminals L1, L2
and L3. Generator current has to be connected to L1l and COM terminals only.

Current measurement
To ensure proper function
Use cables of 2,5mm

Set points adjustment
To run a single-phase application, the following set points have to be set:
Gener protect: Curr unbal to 200 %
Gener protect: Curr unbal del to 60,0 s
Hint:
In version 1.4 and lower increase Basic setting: Nomin current to avoid activation of current
unbalance protection after 1 minute full load running. (Current unbalance limit is 100% of Nomin
current in IL version 1.4 and lower.)
Analog inputs
Three analog inputs are available on the IL-CU
Configuration
Each analog input can be configured by LiteEdit software following way.
