4.1 Alternative EMC cable glands
If you need stainless steel EMC cable glands, you can purchase them from corresponding
suppliers. Please note that the cable glands must be approved for the respective
applications. See Service and support
(http://www.siemens.com/automation/service&support
)
Note
Further information can be found under Ordering data (Page 22)
4.2 Selection of suitable cables
Signal cable
The junction box is connected to the weighing module by means of a signal cable. Use a
shielded cable with six cores as the signal cable. We recommend the SIWAREX cable
Li2Y2x0.75St+2x(2x0.34St)-CY:
● For standard applications: 7MH4702-8AG, orange sheath color.
● For intrinsically safe Ex applications: 7MH4702-8AF, light blue sheath color.
The cables and lines must correspond to the installation regulations according to EN 60079-
14. In hazardous areas, the diameter of individual conductors must not be smaller than 0.1
mm.
WARNING
Short circuit/explosion hazard
At an ambient temperature T ≥ 60 °C, use heat-resistant cables which are approved for an
ambient temperature at least 20 K higher.
Note
The maximum cable length between the load cell and the weighing module is stated in the
weighing module documentation.

4.2 Selection of suitable cables
SIWAREX JB stainless steel with ATEX certificate
Compact Operating Instructions, 06/2010, A5E01257284C-01

Suitable cables for spring-loaded terminals
The following cables are suitable for connecting to the spring-loaded terminals
Cross section Design
0.08 ... 1.5 mm²
AWG 28 ... 16
• Solid
• Stranded
• Finely-stranded - with galvanized individual wires
• Finely-stranded - compacted strands
• Finely-stranded with gas-tight crimped-on pin cable lug
0.08 ... 1 mm²
AWG 28 ... 18
• Finely-stranded with gas-tight crimped-on end sleeves
CAUTION
Short-circuit
Use end sleeves for small conductor cross-sections.
Otherwise the stripped litz wire may buckle when it is inserted into the terminal. In this case,
the line is clamped onto the insulation, which will cause contact problems.
Load cell cables
DMS load cells are supplied with connecting cables.
Connecting a PAL cable
For non-intrinsically safe use of the junction box, a PAL cable must be connected. An M6x12
bolt is provided for this on the mounting flange. The PAL cable must be protected against
becoming loose on its own, which is achieved by a cable eye crimped to the cable.
WARNING
Danger of explosion
Please observe that in the case of shielded cables of intrinsically safe circuits in hazardous
areas, only one grounding is permissible.
If grounding is to be on both sides, an equipotential bonding conductor with at least 4 mm²
must be connected.

Requirements
CAUTION
Loss of degree of protection
Prior to closing the cover, check to ensure that:
• No dirt or cable residues are in the enclosure.
Such residues could lead to faults or short-circuits.
• The sealing surfaces are clean.
• The necessary cable glands are installed and screwed tightly in place.
• Unused openings are closed using the supplied screw plugs.
WARNING
Loss of degree of protection
Degree of protection IP66 is only guaranteed if the device was installed perfectly.
Please note that if the device is open or not completely closed, this degree of protection is
no longer guaranteed.
Procedure
1. Place the cover and screw it on properly.

6.3 Explosion protection
SIWAREX JB stainless steel with ATEX certificate
20 Compact Operating Instructions, 06/2010, A5E01257284C-01
6.3 Explosion protection
In hazardous areas, it is only permitted to use components with the appropriate Ex approval.
The junction box can be used in hazardous areas even for connecting an intrinsically safe
circuit according to EN 60079-14 or EN 61241-14.
In zone 20, certified circuits in category ia, ib or iaD, ibD are permitted.
The terminals meet the requirements for disconnecting intrinsically safe circuits: The
creepage distance and clearance are greater than 8 mm.
Only connect the device to circuits that comply with the technical data specified on the
nameplate or on the certificates and approvals (e.g., the EC-type examination certificates). If
the circuits do not comply with the information in the certificates and approvals, then the
safety required for the approval is longer guaranteed.
When using the junction box for type of protection nA, the junction box must be included in
the local potential equalization. The external and internal connection in the cover must be
used for this purpose. Use a cable eye that is crimped to the cable to do this. The minimum
cross-section of the PAL connecting cable must be the same or greater than the crosssection of the phase conductor. The washer that is also to be used must ensure that the
contact pressure is permanently maintained. The four cover screws must be screwed tight.
Before loosening the cover screws, all of the circuits must be de-energized.
The circuits that are connected must be either only intrinsically safe or only non-intrinsically
safe. Mixing is not allowed.
If the SIWAREX JB junction box is operated with the marking
II 1 D Ex tb + ib IIIC T85°C Da IP66 in hazardous zone 20, then the feeding circuit must
meet the requirements of protection type "intrinisically safe" Cat. ia or Cat. ib in connection
with another recognized protection type.
6.4 Electromagnetic compatibility
The SIWAREX JB junction box meets the following EMC requirements:
● EN 61326: 1999
● EN 45501: 1992
● NAMUR NE21: 2004
To maintain the electromagnetic compatibility, for example,
● ensure that the cables are routed with electromagnetic compatibility (even within
cabinets!).
● lay the signal cable segregated from cables with voltages > 60 V or high currents.
● avoid sites neighboring large electrical systems
