Installation and Connection
Voltage Measuring Inputs
The device is provided with 4 voltage measuring inputs: three for measuring the phase-to-phase voltages (
»V12«
,
»V23«
, »V31«
) or phase-to-neutral voltages (
»VL1«, »VL2«
, »VL3«) and one for the measuring of the residual
voltage »VE«. With the field parameters the correct connection of the voltage measuring inputs has to be set:
phase-to-neutral (star)
phase-to-phase (Open Delta respectively V-Connection)
Ensure the correct tightening torques.
The rotating field of your power supply system has to be taken in to account.
Make sure that the transformer is wired correctly.
For the V-connection the parameter »VT con« has to be set to »phase-to-
phase«.
Please refer to the Technical Data.
