General information
These safety instructions apply to the indicating and adjustment unit VEGADIS DIS61.CC/O**,
DIS81.CC/O****** according to Certificate CSA 14.2662675 (certificate number on the type label)
and to all instruments with the number of the safety instruction (48924) on the type label.
The VEGADIS DIS61.CC/O**, DIS81.CC/O****** is used for separate scaling and visualization of
measured values.
The VEGADIS DIS61.CC/O**, DIS81.CC/O****** is suitable for applications in hazardous atmospheres of all combustible materials of explosion group IIA, IIB and IIC, for applications requiring
EPL-Ga- or EPL-Gb-instruments, as well as Class I, II and III Division 1 and 2 Hazardous Locations.
The atmospheres can also be combustible gases, mists, vapours, dusts, fibers or flyings.
If the VEGADIS DIS61.CC/O**, DIS81.CC/O****** are installed and operated in hazardous areas,
the general Ex installation regulations IEC 60079-14 as well as these safety instructions must be
observed. For installations in Class I, II and III Division 1 and 2 Hazardous Locations, the installtion
control diagram from Chapter 6 of these Safety Instructions must be followed.
The operating instructions as well as the corresponding valid Ex installation regulations or standards for electrical equipment must generally be observed.
The installation of explosion-endangered systems must always be carried out by qualified personnel.

Application conditions
The max. permissible ambient temperatures depending on the temperature classes are specified in
the following tables.
Division 1/EPL-Ga installations
Temperature class
Temperature on the electronics housing
T6
-20 … +37 °C
T5
-20 … +50 °C
T4, T3, T2, T1
-20 … +60 °C
For applications requiring EPL-Ga-instruments, the pressure of the explosive mixtures must be between 0.8 … 1.1 bar. The application conditions during operation in areas with no explosive mixtures
are stated in the manufacturer information.

Notes:
The Intrinsic Safety Entity concept allows the interconnection of two CSA certified intrinsically safe
devices with entity parameters not specifically examined in combination as a system when:
UO or VOC or Vt ≤ Vmax
IO or ISC or It ≤ Imax
PO ≤ Pi
Ca or CO ≥ Ccable
La or LO ≥ Lcable
For Division 2 installations, the Associated Appartus is required to be CSA Certified under Entity
Concept if the VEGA-Sensor is installed in accordance with the Canadian Electrial Code, CSA
C22.1 Part 1 Appendix F, for division 2 wiring methods excluding Nonincendive field wiring.
48924-EN-150113
Dust-tight conduit seal shall be used when installed in Class II and Class III enviroments.
Control equipment connected to the Associated apparatus shall not use or generate more than
250 Vrms or Vdc.
Division 1 installations should be in accordance with ANSI/ISA RP12.06.01 "Installation of Intrinsically Safe Systems for Hazardous (Classified) Locations" and the Canadian Electrical Code under
Entity Concept.
The configuration of associated apparatus shall be CSA Certified under Entity Concept.

Associated Apparatus manufacurer's installation drawing shall be followed when installing this
equipment.
The configuration of Field Device shall be CSA certified under Entity Concept.
The Field Device manufacturer's installation drawing shall be followed when installing this equipment.
VEGA Sensor is CSA certified for Class I, Zone 0, application. If connecting AEx ib Associated
Apparatus or AEx ib I.S. Field Device to the VEGA Sensor the I.X circuit is only suitable for Class I,
Zone 1, and is not suitable for Class I, Zone 0 or Class I, Division 1, Hazardous (Classified) Locations.
No revision to dawing without prior Agency Approval.
WARNING: Substitution of components may impair suitability for hazardous locations.
If the Electrical parameters are unknown, the following values may be used:
Ccable = 60 pF/ft
Lcable = 0.20 µH/ft
