Backup fuses
Maximum backup fuse sizes which may be used for
MP 204 appear from the table below:
At motor currents up to and including 120 A, the
cables to the motor can be taken directly through the
L1-L2-L3 of MP 204.
At motor currents above 120 A, current transformers
must be used.
If backup fuses above 50 A are used, the L1-L2-L3
and "5" to MP 204 must be protected separately with
maximum 10 A fuses.
If current transformers are used, the L1-L2-L3 and
"5" to MP 204 must be protected with maximum 10 A
fuses.
WARNING
Electric shock
Death or serious
personal injury
- Before starting any
work on the product,
make sure that the
power supply has been
switched off and that it
cannot be accidentally
switched on.
- Ensure that the power
and sensor cables are
separated when
mounting the relay
output connections.
- Make sure that the
wiring polarity matches
the installation
instructions.
WARNING

be supplied with pump
voltage if it exceeds
the rating mentioned
on the nameplate.
- Ensure that the branch

Three-phase system
The wiring diagram shows an example of a three-
phase pump with insulation measurement.
The connections to L1, L2, L3 and "5" can be made
with a cable of up to 10 mm2. A special fuse unit up
to approximately 50 A is therefore not required.
If larger backup fuses are used, the voltage to the
L1, L2 and L3 must be protected separately. We
recommend a maximum of 10 A or less.
