Areas
The following section applies to fieldbus junction boxes that are
explosion-hazardous (classified) locations.The information applies only in combination with the
corresponding datasheets. The datasheets are available online at http://www.pepperl-
fuchs.com.
Fieldbus junction boxes for installation in non-hazardous areas are available in 2 variants:
■
Fieldbus junction boxes without short circuit current limitation at the output (spur), F*-JB-
... (* = 2, 3, 4)
■
Fieldbus junction boxes with short circuit current limitation at the output (spur), so-called
Segment Protectors, F2-JBSC-...
5.1
Intended Use
Fieldbus devices are often connected via spurs to the main line (trunk) of the fieldbus. Fieldbus
junction boxes connect fieldbus devices to a fieldbus transmission line (main line, or trunk).
The following versions are available with different outputs for connecting field devices:
■
F2-JB-... and F2-JBSC-... for up to 8 field devices
■
F3-JB-... for up to 2 field devices
■
F4-JB-... for 1 field device
For details on the type code, see chapter 2.
Fieldbus junction boxes can be installed in any fieldbus system using "Manchester bus
powered" technology corresponding to IEC 61158-2 / ISA S50.02 for the United States of
America.
All applicable laws or Directives for the application or planned use must be observed.
Fieldbus junction boxes are only approved for proper professional usage in accordance with
the intended uses. Improper handling voids any claim made under the warrantee and any
manufacturer's liability.
Fieldbus junction boxes may only be operated by trained and qualified personnel in
accordance with this documentation.
