6 Checking the correct installation
6.1
By means of the PC-Software
Voltage (at least 20% U
rated
) and current (at least 2% I
rated
) must be connected
Using the connection check, which is integrated in the visualization of the instantaneous values, the correct
connection of the current and voltage inputs may be checked. The phase sequence will be checked, as well as
if there are open connections or reversed current connections (which change the direction of the current).
The image below shows open current connections (red description
I1
,
I2
,
I3
). This arises because the individual
currents are below 2% of the rated value.

Via measurement display
A simplified connection control is available also via display. See:
B4.7 Measurements for wiring control
If the device indicates no voltage, even if voltage should be present, check
the fuse of the
(see chapter 2).
