Danger:
The
bridges must never be used with single instruments or at the end
of a row of instruments. If this rule is not heeded, there is a danger of
coming into contact with the operating voltage or causing a short
circuit.
A VEGATOR 631 Ex in E
x version is an auxiliary, intrinsically safe
instrument and must not be installed in explosion-endangered areas.
Before setup, the Ex separating chamber must be attached (as shown
below) with Ex versions. Safe operation can be only ensured if the
operating instructions manual and the EG type approval certificate are
observed. VEGATOR 631 Ex must not be opened.
Close the upper terminals according to the following illustration.

With a VEGATO
R 631 Ex in Ex version, the supplied coded pins (type
coded pin and Ex coded pin) must be inserted by the user according to
