Connection examples

Some connection examples for the following types of connection are listed below:
● 3P4W - 3 phases, 4 conductors
● 1P2W - 1 phase, 2 conductors
The selection of the connection types in the device can differ according to the device
version.
For the 5 A device it is only possible to measure the current with current transformers.
For the 65 A device, no current transformers may be connected.
All input or output terminals not required for measuring remain free.
In the connection examples, the secondary side of the transformer can optionally be
grounded at the "l" terminal. It can be grounded at either the "k" or the "l" terminal.
The grounding has no impact on the measurement.
Parameterization of the devices is described in section Parameterizing the device (Page 58).
NOTICE
Grounding of current transformers optional
The connection of the transformers and thus also the grounding of the transformers on the
secondary side must always be carried out according to the applicable regulations.
Grounding of the current transformers on the secondary side is not necessary for use in
low-voltage switchboards for performing measuring tasks.
Protection of the voltage measuring inputs
The fuses in the voltage measuring inputs are only used for cable protection. Selection of
the fuse depends on the supply cable dimensioning. The relevant applicable regulations
must be complied with.
