Installation/commissioning
This chapter of the instruction manual applies to all fieldbus junction boxes.
7.1
General
Fieldbus junction boxes may only be operatedby trained professionals in accordance
with these operating instructions.
Please take the cable parameters to be used from the installation instructions of the
corresponding fieldbus system.
• The insulating length of the leads is 9 mm (only for fieldbus junction boxes with
screw terminals).
• If stranded wires are used, the wire ends must be protected from fraying, for
instance by using end splices.
• The following identifying values must be observed when connecting fieldbus
transmission lines:
• Tightening torque of the screw terminals (if present) 0. 4... 0.5 Nm
• Tightening torques of the screwed connection of cable pass-throughs:
The tightening torques of cap nuts depend on what type of cable is used and must
therefore be determined by the user. The cap nuts must be securely tightened.
Tightening the cap nuts too tight can have a negative effect on the protection class.
The following figures should be taken as rough guides:

Table 7.1: Tightening torques
The tightening torques given in Table 7.1 are valid for fieldbus junction
boxes for which identical cable glands are used for both trunks and
spurs. It is possible for fieldbus junction boxes to be installed with different connection types for trunks and spurs (see Chapter 1). The tightening torques given in Table 7.1 are valid whether or not, for instance,
cable glands are used for the trunk or the spurs or both.
The cap nut of the connector is to be hand-tightened.
Unused connectors must be secured in such a way that the ignition protection class
is maintained.
For fieldbus junction boxes with cable glands, power must always be supplied through
the input, that is, through the second cable gland from the right (as seen from above)
(compare Figure 8.1 and Figure 8.2).

Fieldbus junction boxes may be installed in accordance with their ratings in zones 0,
1 or 2, or in Class I Div. 1 and 2, Class II Div. 1 and 2 or Class III Div. 1 and 2.
In category 1 CG (zone 0), the power supply circuit must comply with
ignition protection class "ia".
Fieldbus junction boxes must be protected from electrostatic charge.
The Declaration of Conformity must be observed. It is especially
important to maintain any "special conditions" that may be indicated.
If installation is performed in compliance with the FISCO model, the maximum length
of each spur is limited to 30 m.
If stranded wires are used in hazardous areas, the wire ends must be protected from
fraying, for instance by using end splices.
The diameter of individual wires in hazardous areas may not be less than 0.1 mm.
This also applies to the individual strands of stranded wires.

Installation/commissioning
7.2.1 Fieldbus junction box Ex i in field housing F…-JB-I-...
For metallic housings in hazardous areas, a suitable potential equalization compliant
with EN 60 079 is required. A ground screw is provided for this purpose on the
F2 housings, and a ground terminal on the F3/F4 housings. Connections must be
secured against loosening and protected against corrosion. Corrosion protection can
be achieved, for example, by using tinned cable plates.
Only permanently laid cables and lines must be fed into the cable glands. For the permissible cable diameters, please refer to the respective data sheet. The operator
must provide a suitable strain relief (for instance, a suitable cable clamp). The
mounting notes in Chapter 6.2.1 must be observed.
Before closing the cover, a visual inspection should be performed to ensure that the
cover seal shows no visible damage. In case of damage, the seal must be replaced
with an original seal.
The screws on the cover should be tightened to a torque of 2.5 Nm.
7.3
Fieldbus junction boxes with short-circuit current limiting for Category 3 G
The integrated fieldbus resistor may only be connected if
• the fieldbus junction box is the last one on the fieldbus segment and
• the fieldbus resistor of the field device is not in use.
The position of the slide switch can be seen in Figure 8.1 for the F2 housings, in Figure 8.2 for the F3 housing, or in Figure 8.4 for the F4 housing.
Only devices suitable for operation in hazardous areas in Zone 2 or Class I, Division
2 and the local operating conditions may be connected to these circuits (see manufacturer's statement or certificate from inspection authorities).
The fieldbus junction box R-JBSC-... should be set up in such a way
that at least protection class IP54 according to EN 60529 is maintained.
All unused cable glands must be plugged with a suitable closing plug or replaced
by a suitable closing screw. The closing plugs and screws must be suitable for this
application.
Unused M12 and 7/8" connectors must be secured in such a way that
protection class IP54 according to EN 60529 is maintained.

7.4
Grounding / shielding of fieldbus transmission lines
Shielding connections of spurs are connected internally with the "S" terminal. Shielding connections of trunks are connected internally with the "T" terminal.
The terminals
are connected with the external grounding clamp.
If the shields of spurs will be hard grounded, only terminal S needs to be
connected via accessory part JB-BR-TB with one of the terminals .
If the shields of trunks will be hard grounded, only terminal T needs to be
connected via accessory part JB-BR-TB with one of the terminals .
By connecting a suitable capacitor between the
and "S" or"T" clamps, a capacitive
ground of the shield of the corresponding fieldbus transmission line is achieved.
If terminals "S" or "T" are not connected with terminal
transmission line in question is not grounded.
, the shield of the fieldbus
Part No. 124147, date of issue 16.08.2007
If the shield of the trunk or spurs of a fieldbus transmission line is grounded due to
EMC considerations, Section 12.2.2.3 of EN 60079-14 and Section 3.3.3 of the PNO
Handbook PROFIBUS MBP, or Sections 6.2 and 6.3 of the FOUNDATION Fieldbus
Application Guides, should be closely observed.
