Installation of circuit breakers
Information
Circuit breakers are not included in the scope of sup-
ply and must be installed by a qualified electrician.
The energy manager has no internal fuses; conse-
quently the inputs for voltage measurement, the ex-
ternal voltage supply and the relay on the energy
manager must be secured with appropriate series
fuses.
– Operation of the energy manager requires that all
supply cables be protected against overcurrent.
In this process, it is important to select fuses
with sensitive trip characteristics.
– The selection of fuse elements is determined by
the commercially available components of the
relevant country of use.
–
Components with the lowest trip current and trip
time must be used.
