2 APPLICATION CONDITIONS FOR THE UNITS
2.1 Special conditions
2.1.1 Short-circuit protection
As a short-circuit protection, each magnet must be connected in series
with a fuse corresponding to its rated current (max. 3 x I
b
according to IEC
60127-2-1) or a motor protector switch with a fast-acting short-circuit and
thermal trip (set to the rated current). For very small rated currents for the
magnets, the fuse with the smallest current value according to the abo-
ve-mentioned IEC standard will suffice. This fuse may be mounted in the
associated supply unit or must be connected in series separately. The rated
voltage of the fuse must be equal to or larger than the quoted nominal vol-
tage of the magnet. The switch-off capability of the fuse cartridge must be
equal to or greater than the maximum theoretical short-circuit current at the
installation location (normally 1500 A).
For the valve types 0641, 2832, 6013 and 6022 in the versions without
fuses, the short-circuit protection must be guaranteed by the operator. For
the version with a fuse, the latter is built into the terminal box of the device. A
more detailed description of the models can be found in the
Technical Data
section of the various models.
