Mounting
Ex-version
Ex-separating chamber
To ensure sufficient “Air and creeping
distances“, an Ex-separating chamber must
be mounted to the connections of VEGATOR.
Loop the lines through the Ex-separating
chamber and connect the lines. Fasten the
Ex-separating chamber with the lower holding
screw. Note the operating instruction of the
carrier BGT 596␣ Ex.
Blind cover
Mounting in carriers
When you mount your VEGATOR with Ex-
approval in a carrier, you have to use a VEGA-
Ex-module. Keep a distance of at least 10 mm
(2 TE) to modules of other manufacturers.
When you want to mount VEGATOR to the
complete left in the carrier, you have to mount
a blind cover of at least 20 mm (4 TE) in front
of the module of the instrument.
Protection with Ex-applications
In Ex-applications a protection of IP 20 must
be kept in mounted condition. Hence cover
the gaps or free modules from the front by
appropriate blind covers.
