Caution
The control voltage as well as the applied measuring voltage of the device
must be protected by means of a back-up fuse.
When connecting the current transformers, the energy flow direction and
the correct assignment to the voltage path must be observed!
Note
Observe the following points when connecting the device:
Energy flow direction
Assignment of measuring voltage input / current transformer input
3.2
Current transformer connection:
Energy flow direction
:
When installing a transformer, take the current flow or energy flow direction
into account. If the current transformer is mounted the wrong way round, the
measured current value will be negative.
Prerequisite is that energy is consumed.
Assigning measuring voltage input / current transformer input:
The current transformer on terminal 20/21 (k1/l1) must be arranged in the
phase where the measuring voltage for terminal 10 (L1) is measured.
- The device will display positive current when connection and energy flow
direction are correct.
- The device will display negative current when the connection is incorrect.
Change the connections until the display shows correct values.
The same applies to the inputs of phases L2 and L3.
Caution
Short out the transformer before doing any changes!
