Specific Conditions of Use (Special Conditions)
The following conditions relate to safe installation and/or use of the equipment.
8 .1
For Group I, the modules shall each be mounted within an enclosure providing a
degree of protection of at least IP54.
This shall be in accordance with EN 60529, and the modules installed in a manner
that does not impair the existing creepage and clearance distances. The enclosure
shall also comply with the appropriate requirements of Clauses 7.4.2 and 7.5, or 8.2
of EN 60079-0.
8 .2
For Group II, the RJ45 connectors shall be fitted with either a plug or blanking
plug.Alternatively, the module shall be mounted in an enclosure providing a degree
of
protection
of
at
least
IP20.
This shall be in accordance with EN 60529, and the modules installed in a manner
that does not impair the existing creepage and clearance distances. The enclosure
shall also comply with the appropriate requirements of Clauses 7.4.2 and 7.5, or 8.3
of EN 60079-0.
8 .3
For Group III, the module shall be mounted inside a suitably certified enclosure
which provides a minimum degree of protection of at least IP54. The module shall
be installed in a manner that does not impair the existing creepage and clearance
distances.
8 .4
The supply to the modules must be derived from a suitably certified, intrinsically
safe supply.
8 .5
The values of Co and Lo shall apply when one of the two conditions below is
given:
- The total Li of the external circuit (excluding the cable) is < 1% of the Lo value, or
- The total Ci of the external circuit (excluding the cable) is < 1% of the Co value.
The above parameters are reduced to 50% when both of the two conditions below
are given:
- The total Li of the external circuit (excluding the cable) > 1% of the Lo, and
- The total Ci of the external circuit (excluding the cable) > 1% of the Co.
Note: the reduced capacitance of the external circuit (including cable) shall not be
greater than 1µF for Group I and IIB/III and 600 nF for IIC.
8 .6
The equipment shall be mounted on an earthed metal bracket or housing.
Marking
Each device is marked in accordance with the Directive and CE marked with the
Notified Body Identification Number.
