Mounting
Ex-version
Note!
VEGATRENN must be generally mounted outside
hazardous areas or special Ex-protective measures
must be taken.
Ex-separating chamber
To ensure suffcient "air and creeping distances", an
Ex-separating chamber must be mounted to the
connections of VEGATRENN. Loop the wires through
the Ex-separating chamber and connect them. Fasten
the Ex-separating chamber with the lower screw.
Observe the operating instruction of carrier
BGT 596 Ex.M.
Protection for Ex-applications
In Ex-applications a protection of IP 20 must be kept.
Cover the spaces or not used modules from the front
by appropriate blind covers.
Mounting in carriers
If you mount your VEGATRENN 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. If you want to mount the VEGATRENN
in the extreme left position 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.
