II 3G ATEX Information
1. Certification number DEMKO 09 ATEX0812123x
2. Ambient range (-40
°C ≤ Tamb ≤ 75°C)
3. Certification string (Ex nC nL IIC T4)
4. Standards covered ( EN60079-0:2006, EN60079-15:2005)
5. The conditions of safe usage:
y The Ethernet Communication Devices are to be mounted in an IP54
enclosure and used in an area of not more than pollution degree 2 as
defined by IEC60664-1. A 4mm2 conductor must be used when a
connection to the external grounding screw is used. Conductors
suitable for use in an ambient temperature of 93
°C must be used for the
Power Supply Terminal.
y Provisions shall be made, either in external to the apparatus, to prevent
the rated voltage being exceeded by the transient disturbances of more
than 40%.
Wiring Requirements
WARNING Do not disconnect modules or wires unless power has been
switched off or the area is known to be non hazardous.
The devices may only be connected to the supply voltage
shown on the type plate.
The devices are designed for operation with a safety
extra-low voltage. Thus, they may only be connected to the
supply voltage connections and to the signal contact with the
safety extra-low voltages (SELV) in compliance with
IEC950/ EN60950/ VDE0805.
WARNING Substitution of components may impair suitability for Class
I, Division 2 and Zone 2.
These devices must be supplied by a SELV source as defined
in the Low Voltage Directive 73/23/EEC and 93/68/EEC.
