Energy ow direction: When mounting the transformer, observe the current ow or
energy ow direction. If the current transformer is mounted the wrong way round, the
measured current value will be negative.
A prerequisite for this is that energy is supplied to the device.
Assignment - Measuring voltage input / Current transformer input:
The current transformer on terminal 20/21 (k1/l1) must be installed in the phase in
which the measuring voltage for terminal 10 (L1) is measured.
– The device will display positive current when connection
and energy ow direction are correct.
- If connected incorrectly, the current displayed is negative. Interchange
the connections until the display shows correct values.
CAUTION
Before any interchanging, the current transformer must be shorted out!
