The energy manager does not have any internal
fuses, which means that the inputs of the voltage
measurement, the external power supply and the re-
lay must be protected with suitable back-up fuses.
–
The operation of the energy manager requires
overcurrent protection of all supply lines. It is
important to select fuses with sensitive tripping
criteria.
– The selection of fuse elements is based on the
commercially available components of the re-
spective country of use.
–
Components with the lowest tripping current
and the shortest tripping time must be used.
