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.
