Connecting fuse monitoring equipment

One or more C98043-A7118 fuse monitoring units can be used to monitor the fuses of one
or more power units. Both the cables and the voltage measurement equipment need to be
plugged in. Each pair of neighboring mounting tabs forms a monitoring unit. Fuse monitoring
equipment does not generate any ground leakage current.
Up to 5 groups, each containing 6 fuse monitoring units, can be connected in parallel. The
fuse monitoring distributor module C98043-A7112 is used for this purpose, with plug
connector X23B on the individual fuse monitoring unit being plugged in on the distributor
module and X23A on the distributor module being plugged in at X23A on power interface
C98043-A7109. This supports isolated monitoring of up to 30 individual fuses or 60, if there
are 2 for each phase.
Parameter p51831[0 to 4] can be used to activate the individual fuse monitoring modules by
entering "1".
Modules C98043-A7112 and C98043-A7118 can be ordered as spare parts. Please refer to
the preface for information on spare parts.
All connection work must be carried out while the cabinet is de-energized. Connecting the
monitoring equipment incorrectly can lead to it being damaged or destroyed. Failure to
observe this warning information can result in death, serious physical injury, or extensive
material damage.
