4 Instruction manual
These instructions apply in conjunction with the respective data sheets. You can ac-
cess the data sheets at www.pepperl-fuchs.com.
The data sheet lists the electrical characteristics of the EC declaration of conformity
and is considered and integral part of the instruction manual.
4.1 Intended use
The FieldBarrier serves as a galvanic isolation between intrinsically safe and non-in-
trinsically safe fieldbuses.
The FieldBarrier can be used for all fieldbus systems using "Manchester Coding Bus
Powered“ physical layout in accordance with IEC 61158-2.
The inputs of the field FieldBarrier are designed in the "Increased safety“ ignition pro-
tection method. The outputs of the FieldBarrier are designed in the "Intrinsic Safety“
ignition protection method and make it possible to operate intrinsically safe field de-
vices.
Data sheets for FieldBarriers contain the electrical data of the EC declaration of con-
formity and are considered an integral part of the instruction manual.
The FieldBarrier may be installed in hazardous areas of category 2G / Zone 1 and
Zone 22 (non-conductive dust).
Laws and/or regulations governing the use or intended usage goal must be observed.
FieldBarriers are only approved for proper professional usage in accordance with the
intended purposes. Improper handling will void any claim made under the warrantee
and any manufacturer's liability.
The device can only be operated by trained professionals in accordance with the
available instruction manual.
The operator of the system bears the responsibility in terms of planning,
mounting, commissioning, operation and maintenance, especially in
conjunction with applications in areas subject to the danger of explo-
sion.
FieldBarriers that are operated in general electrical systems must not
thereafter be operated in electrical systems that are connected with
hazardous areas.
Protection of operating personnel and the system is not ensured if the
module is not used in accordance with its intended purpose.
