2. OPERATIN CONDITIONS FOR THE DEVICES
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 Ib 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 above-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 voltage of the magnet. The switch-off capability of the fuse car-
tridge must be equal to or greater than the maximum theoretical short-circuit current
at the installation location (normally 1500 A).
In the case of versions A and L of the solenoid, short-circuit protection must
be assured by the operator. In the case of version K of the solenoid, the fuse is
installed in the terminal box of the device. More detailed descriptions of versions A,
L and K are to be found in the section Technical Data.
Fuse ... A
2.1.2. Operation with associated valve body

DANGER!
Risk of explosion!
• When using the devices in petrol pumps for the control of petrol in
