3.1 Installation information
Generally the following instructions must be
noted for installation:
Installation place
VEGATRENN 547 V Ex as well as the
appropriate signal conditioning instrument
must be generally installed outside the
hazardous area.
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 creep 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 instructions 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 ( 2TE) to module
cards of other manufacturers. If 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 intrinscially 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.
