The data sheet for fieldbus terminators contains electrical data of the EC type-exami-
nation certificate and additional information. It is considered part of this instruction
manual.
The fieldbus terminator is used in bus systems (PROFIBUS PA or FOUNDATION
fieldbus) based on the Fisco model. It is manufactured in a flame-
proof and intrinsically safe design and is clearly identified by the labeling on the rating
plate.
This symbol indicates a warning about a possible danger.
In the event the warning is ignored, the consequences may range from
personal injury to death or from damage to equipment to destruction.
This symbol warns of a possible fault.
Failure to observe the instructions given in this warning may result in
the device and any facilities or systems connected to it developing a
fault or even failing completely.
This symbol brings important information to your attention.
The data sheet can be downloaded from www.pepperl-fuchs.com.

Laws and/or regulations governing the use or intended usage must be observed.
3 Use of the flameproof version
The flameproof fieldbus terminator can be used in the following manner:
• Installation in the wall of equipment or housing suitable for this purpose of ignition
protection class "flameproof enclosure" of Groups IIA, IIB and IIC.
• Installation in the wall of equipment or housing suitable for this purpose of the "in-
creased safety" ignition protection class.
4 Use of the intrinsically safe version
The intrinsically safe fieldbus terminator can be used in the following manner:
• Installation in the housing wall of equipment (device) suitable for this purpose of the
"intrinsic safety ia" ignition protection class in Category 1G (Zone0), 2G (Zone1) or
3G (Zone2).
• Installation in the housing wall of equipment (device) suitable for this purpose of the
"intrinsic safety ib" ignition protection class in Category 2G (Zone1) or 3G (Zone2).
• In intrinsically safe circuits of Group IIA, IIB or IIC
• Installation in the housing wall of equipment or housing suitable for this purpose of
ignition the "flameproof enclosure" protection class, switching in circuits of ignition
protection type "intrinsic safety ia or ib" in Category 2G (Zone1) or 3G (Zone2).
• Installation in the housing wall of equipment or housing suitable for this purpose of
ignition the "increased safety" protection class, switching in circuits of ignition pro-
tection type "intrinsic safety ia or ib" in Category 2G (Zone1) or 3G (Zone2).
In accordance with this identification, devices that have been operated
in general electrical systems must no longer be used in electrical sys-
tems that are in contact with hazardous areas
Fieldbus terminators 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.

6 Ambient temperature range
The fieldbus terminator can be used with the following ambient temperatures:
• In the temperature class T6 up to 60 °C ambient temperature
• In the temperature class T5 up to 75 °C ambient temperature
• In the temperature class T4 up to 85 °C ambient temperature
7 Installation and commissioning
7.1 General information
• Circuits must be installed in accordance with recognised rules of the industry and
requirements of the company where the installation is performed
• Potential equalisation must be ensured by the way the device is attached.
Fieldbus terminators are designed in protection class IP67 and must
accordingly be protected against adverse ambient conditions.
The EC type-examination certificate and the manufacturer's declaration
of conformity must be observed. It is especially important to observe the
"special conditions" in the EC type-examination certificate.
EN 60079-14/IEC 60079-14 must be observed when installing fieldbus
terminators. For the Federal Republic of Germany, the " National Fore-
word" to DIN 60079-14/VDE 0165 Part 1 must be observed in addition.

7.2 Flameproof version
• The F*-FT-Ex1.D.IEC fieldbus terminator must be installed in accordance with its
identification in Zone 1 or 2.
7.3 Intrinsically safe version
• The F*-FT-Ex1.I.IEC fieldbus terminator must be installed in accordance with its
identification in Zone 0, 1 or 2. The circuit to be supplied with power in Zone0 must
comply with ignition protection class "ia“.
Opening the encapsulation to the Ex d space is prohibited.
The F*-FT-Ex1.D.IEC fieldbus terminator must only be connected when
no voltage is present.
There must be at least 5 thread turns in mechanical connection for
installation in a flameproof housing. There must be a suitable mecha-
nism to prevent the device from coming loose in the threading as well
as one to ensure the IP protection class. This can be achieved in the
following manner:
Use of lock nuts with seals or
Use of Loctite (medium) in the threading bore holes
For installation in a housing with the "increased safety" ignition protec-
tion class, there must be suitable mechanisms to ensure IP protection
and that the device does not turn out of the threadings. This can be
achieved in the following manner:
Use of lock nuts with seals
Use of Loctite (medium) in threading bore holes
A specialist electrician must perform a check after installation!
When connecting intrinsically safe circuits together, EN 60079-14 /
IEC 60079-14 must be observed. For the Federal Republic of Germany,
the " National Foreword" to DIN EN 60079-14 / VDE 0165 Part 1 must
be observed in addition.

8 Mounting and dismounting
9 Repair and maintenance
The transmission behavior of fieldbus terminators is stable even over long periods of
time. There is thus no need for regular adjustments or similar tasks. Maintenance is
therefore not required.
10 Troubleshooting
11 Disposal
Recognised rules of the technology and setup requirements must be
maintained during mounting and dismounting. Especially for tasks on
electrical systems, special safety requirements must be observed.
Following are a few special points to check for commissioning:
• The fieldbus terminator has been installed according to requirements
• The fieldbus terminator is not damaged
• The connection area is clean
• IP protection is ensured
• The fieldbus terminator is installed so that it cannot turn loose from the
threading
• The fieldbus terminator and lock nut are securely tightened
• No parts of the flameproof enclosure are damaged
• In the case of the flameproof version of fieldbus terminators, the sur-
faces bordering on the threading gap must not be further processed or
painted after installation.
No change must be made to fieldbus terminators that are operating in
connection with hazardous areas. In the event of a defect, the fieldbus
terminator must always be disposed of and replaced by a new one.
Packaging and fieldbus distributors must only disposed of in accor-
dance with the requirements of the country in which the fieldbus termi-
nator is installed.
