(230V AC).
The controller has two sets of BB transformer settings, which can be enabled individually in
this measurement system.
4.3.2 Split phase system
This is a special application where two phases and neutral are connected to the controller. The controller
shows phases L1 and L3 in the display. The phase angle between L1 and L3 is 180 degrees. Split phase is
possible between L1-L2 or L1-L3.
The following adjustments must be made to make the system ready for the split phase measuring (example
240/120V AC):

The measurement U
L3L1
shows 240V AC. The voltage alarm setpoints refer to the nominal volt-
age 120V AC, and U
L3L1
does not activate any alarm.
The controller has two sets of BB transformer settings, which can be enabled individually in
this measurement system.
4.3.3 Three-phase system
When the controller is delivered from the factory, the three-phase system is selected. When this principle is
used, all three phases must be connected to the controller.
