Instruction Manual electrical apparatus for hazardous areas
Device category 3G (nA) for use in hazardous areas with gas, vapour and mist
Directive conformity 94/9/EG
Standard conformity EN 60079-0:2006, EN 60079-15:2005
Ignition protection category "n"
Use is restricted to the following stated conditions
CE symbol
Ex-identification ¬ II 3G Ex nA IIC T6 X
The Ex-significant identification is on the enclosed adhesive label
General The apparatus has to be operated according to the appropriate data in the data sheet and in this instruction manual.
The data stated in the data sheet are restricted by this operating instruction! The special conditions must be observed!
Installation, Comissioning Laws and/or regulations and standards governing the use or intended usage goal must be observed.
The adhesive label provided must be affixed in the immediate vicinity of the sensor! The surface to which the label is applied
must be clean, flat and free from grease!
The affixed adhesive label must be readable and durable, taking account of the possibility of chemical corrosion!
Maintenance No changes can be made to apparatus, which are operated in hazardous areas.
Repairs to these apparatus are not possible.
Special conditions
Maximum operating current IL The maximum permissible load current must be restricted to the values given in the following list. High load currents and load
short-circuits are not permitted.
Maximum operating voltage UBmax The maximum permissible operating voltage UB max is restricted to the values in the following list. Tolerances are not per-
missible.
Maximum permissible ambient tempera-
ture TUmax
dependant of the load current IL and the max. operating voltage UBmax.
Information can be taken from the following list.
at UBmax=30 V, IL=200 mA 49 °C (120.2 °F)
at UBmax=30 V, IL=100 mA 54 °C (129.2 °F)
at UBmax=30 V, IL=50 mA 55 °C (131 °F)
Plug connector The plug connector must not be disconnected under voltage. The proximity switch is marked as follows: “DO NOT DISCON-
NECT UNDER VOLTAGE!” When the plug connector is disconnected the ingress of dirt into the inner areas (i.e. the areas,
which are not accessible in the plugged-in condition) must be prevented.
Protection from mechanical danger The sensor must not be exposed to ANY FORM of mechanical danger.
Protection from UV light The sensor and the connection cable must be protected from damaging UV-radiation. This can be achieved when the sensor
is used in internal areas.
Electrostatic charging Electrostatic charges must be avoided on the mechanical housing components. Dangerous electrostatic charges on the
mechanical housing components can be avoided by incorporating these in the equipotential bonding.

Plug connector The plug connector must not be disconnected under voltage. The proximity switch is marked as follows: “DO NOT DISCON-
NECT UNDER VOLTAGE!” When the plug connector is disconnected the ingress of dirt into the inner areas (i.e. the areas,
which are not accessible in the plugged-in condition) must be prevented.
The plug connection can only be separated using a tool. This is achieved by using the locking protection V1-Clip (Mounting
accessory from Pepperl + Fuchs).
Protection from mechanical danger The sensor must not be mechanically damaged.
Electrostatic charging Electrostatic charges must be avoided on the mechanical housing components. Dangerous electrostatic charges on the
mechanical housing components can be avoided by incorporating these in the equipotential bonding.
