Appendix A Hazardous Area Consideration & Labels
CAUTION Aluminum models used in zone 0
Aluminum enclosures are considered a potential risk for
ignition by impact or friction. Care must be taken during
installation and use to prevent impact or friction.
Ex Safety aspects and IP Protection
(Europe)
According to ATEX Directive (European Directive 2014/34/EU)
and relative European Standards which can assure compliance
with Essential Safety Requirements, i.e., EN 60079-0 (General
requirements) EN 60079-1 (Flameproof enclosures "d") EN
60079-26 (Equipment with equipment protection level -EPL-
Ga) EN 60079-28 (Protection of equipment and transmission
systems using optical radiation "op is") EN 60079-31
(Equipment dust ignition protection by enclosure "t") the
LLT100 SERIES has been certified for the following groups,
categories, media of dangerous atmosphere, temperature
classes, types of protection. Examples of application are also
shown below by simple sketches.
a) Certificate ATEX II 2(1) G Ex db [op is T6 Ga] IIC T6...T5 Gb
(for LLT100.XX.A or B – Universal flat face flange)
FM Approvals certificate number
FM16ATEX0032X
The meaning of ATEX code is as follows:
– II: Group for surface areas (other than mines)
– 2: Category (for instrument installed in Cat.2/zone 1)
– (1): Category (for laser aiming in Cat.1/zone 0)
– G: Gas (dangerous media)
– Ex db: Explosion protected by a flameproof enclosure
– [op is T6 Ga]: Optical Intrinsic safety used for equipment
protection level "a" for Gas atmosphere
– IIC: Gas group (all Gas)
– T5: Temperature class of the LLT100 (corresponding to
100 °C max.) with a Ta from –50 °C to +85 °C
– T6: Temperature class of the LLT100 (corresponding to
85 °C max.) with a Ta from –50 °C to +75 °C
– Gb: Equipment protection level "b" for Gas atmosphere
NOTICE
The number indicated on the safety label close to
the instrument CE marking identifies the Notified
Body which has responsibility for surveillance of the
production.
Certificate IECEx Ex db [op is T6 Ga] IIC T6...T5 Gb (for LLT100.
XX.A or B – universal flat face flange)
IECEx certificate number
IECEx FMG 16.0023X
The other marking refers to the protection type used according
to relevant EN/IEC standards:
– Ex db: Explosion protected by a flameproof enclosure
– [op is T6 Ga]: Optical Intrinsic safety used for equipment
protection level "a" for Gas atmosphere
– IIC: Gas group (all gas)
– T5: Temperature class of the LLT100 (corresponding to
100 °C max.) with a Ta from –50 °C to +85 °C
– T6: Temperature class of the LLT100 (corresponding to
85 °C max.) with a Ta from –50 °C to +75 °C
– Gb: Equipment protection level "b" for Gas atmosphere
b) Certificate ATEX II 1/2 (1) G EX db [op is T6 Ga] IIC T6...T5
Ga/Gb (for LLT100.XX.C to G – raised face pressure rated SS
flange)
FM Approvals certificate number
FM16ATEX0032X
The meaning of ATEX code is as follows:
– II: Group for surface areas (other than mines)
– 1/2: Category – only the LLT100 process interface complies
with Cat. 1; the rest of the device complies with Cat. 2
– G: Gas (dangerous media)
– Ex db: Explosion protected by a flameproof enclosure
– [op is T6 Ga]: Optical Intrinsic safety used for equipment
protection level "a" for Gas atmosphere
– IIC: Gas group (all gas)
– T5: Temperature class of the LLT100 (corresponding to
100 °C max.) with a Ta from –50 °C to +85 °C
– T6: Temperature class of the LLT100 (corresponding to
85 °C max.) with a Ta from –50 °C to +75 °C)
– Ga/Gb: Part of the LLT100 complies with Equipment
protection
