Assembly, Connection and Putting into Operation
5.2 Connection
The DL230 is available as officially calibrated or a factory cal-
ibrated device. Information regarding additional equipment
versions of the DL230 can be found under www.elster-
instromet.com.
DANGER!
The connection of non-intrinsically-safe or non-
associated apparatus presents a risk of explosion!
The operation of the DL230 as associated apparatus for zone
0 or 1 and the connection of non-intrinsically-safe equipment
which exceeds those conditions and limit values specified in
the declaration of conformity, presents a risk of explosion.
Therefore:
– When the DL230 is used as associated apparatus only
devices with intrinsically-safe circuits and electrical data
that corresponds to those requirements stipulated in the
declaration of conformity for the DL230 (see Appendix),
should be connected.
–
When connecting the DL230 and putting it into operation, the guide-
lines of the corresponding EN 60079-0 and EN 60079-14 standards
should be observed.
–
The wiring of the connections should be professionally carried out by a
gas specialist or a calibration officer.
–
Active outputs cannot be switched.
–
Connect unused cable glands as per EN 60079-14 with the help of a
plug or a suitable screw cap.
To program the device and carry out further applications the optical inter-
face of the DL230 (see the "Construction and Function" chapter) can be
used. Further details can be found under www.elster-instromet.com.
The connections described below should only be sealed by
a calibration officer. If the DL230 is used for operations,
which are not subject to calibration regulations, the seals on
the respective connections can be omitted.
