The type-examination tested valve solenoid is equipped with a terminal box and a type-tested cable gland.The connection is polarity-independent.

Important:

Corresponding to the rated current, a fuse according to DIN 41571 and EN / IEC 60127 has to be connected ahead of every valve solenoid (max. 3 x I rated ).

The shut-off threshold of the fuse has to match the prospec-tive short-circuit current of the supply source.

The prospective short-circuit current of the supply source may amount to a maximum of 1500 A.

This fuse may only be installed outside the explosive area or must be of an explosion-proof design.
