3.1 Installationinformation
Generally the following instructions must be
noted for installation:
Installation place
VEGATRENN 548 V Ex as well as the
apropriate signal conditioning instrument must
be generally instaled outside the hazardous
areas.
Protection
In Ex-applications protection IP 20 must be
maintained. Cover the gaps or free modules
from the front with appropriate blind covers.
Ex-separating chamber
An Ex-separating chamber must be mounted
to the connections of VEGATRENN to ensure
sufficient „air and creeping distances“. Loop
the cable through the Ex-separating chamber
and connect the cables. Fasten the Ex-
separating chamber with the lower screw.
Note the operating instruction of the carrier
BGT 596 Ex.M.
Mounting in carrier
When you mount VEGATRENN in a carrier, you
have to use a VEGA-Ex-module. Keep a
distance of at least 10 mm (2 TE) to module
cards of other manufacturers. When you want
to mount VEGATRENN in the complete left
position in the carrier, a blind cover of at least
20 mm (4 TE) must be mounted in front of the
module of the instrument.
Separation from not intrinsically safe
circuits
A separating wall must be provided between
the connection parts of intrinsically safe and
not intrinsically safe circuits so that the min.
distance of 50 mm must be kept. When using
a separating chamber (supplied with the
module) this condition is met.
General conditions
In addition the valid „Installation and operating
instructions“ as well as the special conditions
and instructions in the conformity certificates
must be noted.
