Connect one end of the MPLC power cable in the scope of delivery to MPLC ports L1,
L2, and L3 of Logger, and the other end to the three-phase ports of the circuit breaker.
Port L1 of Logger must be connected to phase A of the circuit breaker, port L2 to phase
B, and port L3 to phase C. The details are shown in the following figure.
The external circuit breaker is beyond the scope of delivery, and users need to
prepare it by themselves if necessary.
The external circuit breaker just needs to meet the above two parameters (-
nominal voltage and nominal current). Other parameters, such as breaking
capacity, are not mandatory requirement.
