4.2 Connection to the FOUNDATION Fieldbus™
Devices can be connected to the FOUNDATION Fieldbus™ in two ways:
• Connection via conventional cable gland →Chap. 4.2.1
• Connection via fieldbus connector (optional, can be purchased as an accessory) →Chap. 4.2.2
"Caution!
• Switch off power supply before installing or connecting the field indicator. Failure to observe this
may result in destruction of parts of the electronics.
• Grounding via one of the grounding screws (terminal head, field housing) is recommended.
• Risk of damaging the fieldbus cable!
– If the shielding of the fieldbus cable is grounded at more than one point in systems without
additional potential matching, power supply frequency equalizing currents can occur that
damage the cable or the shielding. In such cases the shielding of the fieldbus cable is to be
grounded on only one side, i.e. it must not be connected to the ground terminal of the housing
(terminal head, field housing). The shield that is not connected should be insulated!
– We recommend that the fieldbus not be looped using conventional cable glands. If you later
replace even just one measuring device, the bus communication will have to be interrupted.

4.2.2 Fieldbus connector
Optionally, a fieldbus connector can be installed in field housing instead of a cable gland. Fieldbus
connectors can be ordered from Endress+Hauser as an accessory (see Section 8 'Accessories').
The connection technology of FOUNDATION Fieldbus™ allows measuring devices to be
connected to the fieldbus via uniform mechanical connections such as T-boxes, junction boxes, etc.
This connection technology using prefabricated distribution modules and plug-in connectors offers
substantial advantages over conventional wiring:
• Field devices can be removed, replaced or added at any time during normal operation.
Communication is not interrupted.
• Installation and maintenance are significantly easier.
• Existing cable infrastructures can be used and expanded instantly, e.g. when constructing new
star distributors using 4-channel or 8-channel distribution modules.

4.3 FOUNDATION Fieldbus™ cable specification
4.3.1 Cable type
Twin-core cables are required for connecting the device to the FOUNDATION Fieldbus™ H1.
Following IEC 61158-2 (MBP), four different cable types (A, B, C, D) can be used with the
FOUNDATION Fieldbus™, only two of which (cable types A and B) are shielded.
• Cable types A or B are particularly preferable for new installations. Only these types have cable
shielding that guarantees adequate protection from electromagnetic interference and thus the
most reliable data transfer. In the case of cable type B, several field buses (same degree of
protection) may be operated in one cable. No other circuits are permissible in the same cable.
• Practical experience has shown that cable types C and D should not be used due to the lack of
shielding, since the freedom from interference generally does not meet the requirements
described in the standard.
The electrical data of the fieldbus cable have not been specified but determine important
characteristics of the design of the fieldbus, such as distances bridged, number of users,
electromagnetic compatibility, etc.
Suitable fieldbus cables (type A) from various manufacturers for non-hazardous areas are listed
below:
• Siemens: 6XV1 830-5BH10
• Belden: 3076F
• Kerpen: CeL-PE/OSCR/PVC/FRLA FB-02YS(ST)YFL
4.3.2 Maximum overall cable length
The maximum network expansion depends on the type of protection and the cable specifications.
The overall cable length combines the length of the main cable and the length of all spurs (>1 m/
3.28 ft). Note the following points:
• The maximum permissible overall cable length depends on the cable type used.
• If repeaters are used, the maximum permissible cable length is doubled. A maximum of three
repeaters are permitted between user and master.

Wiring RID14
16 Endress+Hauser
4.3.3 Maximum spur length
The line between the distribution box and field device is described as a spur.
In the case of non-Ex applications, the max. length of a spur depends on the number of spurs (>1
m/3.28 ft):
4.3.4 Number of field devices
In accordance with IEC 61158-2 (MBP), a maximum of 32 field devices can be connected per
fieldbus segment. However, this number is restricted under certain conditions (explosion
protection, bus power option, field device current consumption). A maximum of four field devices
can be connected to a spur.
4.3.5 Shielding and grounding
Optimum electromagnetic compatibility (EMC) of the fieldbus system can only be guaranteed if the
system components and, in particular, the lines are shielded and the shield forms as complete a
cover as possible.
• To ensure an EMC protective effect, connect the shield as often as possible to the reference
ground.
• For reasons of explosion protection, you should refrain from grounding however.
To comply with both requirements, the FOUNDATION Fieldbus™ basically allows three different
types of shielding:
• Shielding at both ends
• Shielding at one end on the feed side with capacitance connection to the field device
• Shielding at one end on the feed side
Experience shows that the best results with regard to EMC are achieved in most cases in
installations with one-sided shielding. Appropriate measures with regard to input wiring must be
taken to allow unrestricted operation when EMC interference is present. These measures have been
taken into account for this device. Operation in the event of disturbance variables as per NAMUR
NE21 is possible with one-sided shielding.
Where applicable, national installation regulations and guidelines must be observed during the
installation!
Where there are large differences in potential between the individual grounding points, only one
point of the shielding is connected directly with the reference ground. In systems without potential
equalization, therefore, cable shielding of fieldbus systems should only be grounded on one side, for
example at the fieldbus supply unit or at safety barriers, →å10

"Caution!
If the shielding of the cable is grounded at more than one point in systems without potential
matching, power supply frequency equalizing currents can occur that damage the bus cable or
shielding or have a serious effect on signal transmission. In such cases the shielding of the fieldbus
cable is to be grounded on only one side, i.e. it must not be connected to the ground terminal of the
housing (terminal head, field housing). The shield that is not connected should be insulated!
4.3.6 Bus termination
The start and end of each fieldbus segment are always to be terminated with a bus terminator. With
various junction boxes (non-Ex), the bus termination can be activated via a switch. If this is not the
case, a separate bus terminator must be installed. Note the following points in addition:
• In the case of a branched bus segment, the device furthest from the Fieldbus power supply
represents the end of the bus.
• If the fieldbus is extended with a repeater, then the extension must also be terminated at both
ends.
4.3.7 Further information
General information and further points on wiring can be found on www.fieldbus.org, the Web site
of the Fieldbus Foundation or in the Operating Instructions "FOUNDATION Fieldbus™ Overview"
which can also be found on the CD-ROM. (Additional sources: →www.endress.de →Download).

4.4 Degree of protection
The devices fulfill all the requirements for IP 67 degree of protection. Compliance with the
following points is mandatory following installation or servicing in order to ensure that IP 67
protection is maintained:
• The housing seal must be clean and undamaged when inserted into the seal groove. The seal may
have to be cleaned, dried or replaced.
• The cables used for connection must be of the correct specified outside diameter (e.g. M16 x 1.5,
cable diameter from 5 to 10 mm).
• Replace any unused cable entries with dummy plugs.
• The grommet used should not be removed from the cable entry.
• The housing cover and the cable entry must be well tightened.
• Install the device upright in such a way that the cable entries point downwards.

below 0x40), the display will show within the 7-segment area "bad-" and the channel number
where the bad value is published. This channel number can also be found in the 14-segment area.
5.3 FOUNDATION Fieldbus™ technology
The FOUNDATION Fieldbus™ (FF) is a purely digital, serial communication system that connects
fieldbus devices (sensors, actuators), automation and process control systems with each other. As a
local communications network (LAN) for field devices the FF was primarily designed for the
requirements of process technology. The FF thus forms the basic network throughout the hierarchy
of a communication system.
Please refer to Operating Instructions BA 013S/04/en “FOUNDATION Fieldbus Overview:
Installation and Commissioning Guidelines” for configuration information.
