EMR-4000 IM02602009E
Voltage Measuring Inputs
The device is provided with 4 voltage measuring inputs. Three for measuring the mains voltages (
»VAB«
, »VBC«
,
»VCA« - in case of Open Delta
) or phase-to-neutral voltages (
»VA«, »VB«
, »VC« in case of Wye). The fourth
measuring input is to be used for »VX«.
Make sure that the tightening torque is 1.2-1-6 Nm [11-15 In-lb].
The rotating field of your power supply system has to be taken in to account.
Make sure that the voltage transformers are wired correctly.
For the Open Delta connection the system parameter »Main VT con« has to be
set to »Open Delta«.
For the Wye connection the system parameter »Main VT con« has to be set to
»Wye«.
