1.2 Target Group, Personnel
Responsibility for planning, assembly, commissioning, operation, maintenance, and
dismounting lies with the plant operator.
Only appropriately trained and qualified personnel may carry out mounting, installation,
commissioning, operation, maintenance, and dismounting of the product. The personnel must
have read and understood the instruction manual and the further documentation.
nsure that you are familiar with the system and its components before use. Read the
documentation carefully.
Note!
This document does not replace the instruction manuals for the components in use.
The safety information for the components in use determines the specific safety instructions
that apply to the system. The instruction manuals for the components in use must have been
read and understood.
Note!
For complete information about the components in use, refer to the instruction manuals and
additional documentation available online at www.pepperl-fuchs.com.

Introduction
1.3 Symbols Used
This document contains symbols for the identification of warning messages and of informative
messages.
Warning Messages
You will find warning messages, whenever dangers may arise from your actions. It is mandatory
that you observe these warning messages for your personal safety and in order to avoid
property damage.
Depending on the risk level, the warning messages are displayed in descending order as
follows:
Informative Symbols
Action
This symbol indicates a paragraph with instructions. You are prompted to perform an action or
a sequence of actions.
Danger!
This symbol indicates an imminent danger.
Non-observance will result in personal injury or death.
Warning!
This symbol indicates a possible fault or danger.
Non-observance may cause personal injury or serious property damage.
Caution!
This symbol indicates a possible fault.
Non-observance could interrupt the device and any connected systems and plants, or result in
their complete failure.
Note!
This symbol brings important information to your attention.

2.1 Prerequisites for Operating the FB Remote I/O Unit
2.2 Introduction
Remote I/O systems, consisting of I/O modules, gateways, bus termination modules, power
supplies, and a backplane, form the interface for signals to be transmitted from the explosion-
hazardous area ( x area), to the safe area (non-hazardous area). With appropriate surrounding
enclosures, remote I/O systems can be installed in Gas- x areas of Zone 1. Using remote I/O, a
wide range of digital and analog sensors and actuators can be connected to process control
systems over a fieldbus. Specific measures need to be taken to disconnect I/O modules with
x-e front connectors during ongoing operation. To do so, observe the safety notices in this
manual. The gateway is the interface between the I/O modules on the backplane and the
process control system. Power supplies are used to power the I/O modules and com
unit/gateway.
All components of the FB remote I/O with x-q protection meet the FB concept. This simplifies
the evaluation of modules from an explosion protection point of view.
This manual sets out how to work with the hardware. Refer to the software manual for the
gateway and the I/O modules for information on the configuration of the gateway and the I/O
modules.
Note!
Requirements for equipment protection level Gb
Components of the FB remote I/O system may be installed and operated in Zone 1 only if they
are installed in a surrounding enclosure that complies with equipment protection level Gb.
Note!
Certification required
Before commissioning, the components of the FB remote I/O must be certified by an
appropriate certification body together with the surrounding enclosure. nclosures from
Pepperl+Fuchs are supplied fully certified and with complete documentation so that they can
be easily installed straight away.

2.4 Field Units (Surrounding nclosures)
Field units serve to protect all electronic components against environmental influences and are
an integral part of explosion protection. The enclosures are made of glass fiber reinforced
polyester or stainless steel and are available in various versions. The surrounding enclosures
contain backplanes for the connection of modules. The modular concept allows multiple
surrounding enclosures to be flanged together to create the required expansion level. ach
surrounding enclosure contains x-e terminals for power and communication lines. For safety,
these are individually equipped with protective covers (IP30) and touch protection.
The surrounding enclosures are equipped with a rating plate listing all safety-relevant
information, e.g., type of ignition protection, temperature class, permissible ambient
temperature and permissible power.
Plastic enclosure

Glass fiber reinforced polyester offers a high level of mechanical protection for both onshore
and offshore plants.
Stainless steel enclosure

The stainless steel enclosure ensures a high level of corrosion resistance for onshore and
offshore plants.
