5 Cable connections
5.1 General information
In order to use the junction boxes for load cells with 6-wire cables, jumpers J1 and J2 must
be opened; see Chapter
.
Cable entry must be from below.
Fit the wires and screen of the connection cable with wire end ferrules as per DIN 46228-1:
-
0.5 mm
2
for green, gray, black, and white
-
0.75 mm
2
for blue and red
This is not necessary for the load cell cables.
Connect the wires to the terminals according to the color coding .
Place the cable screens of the connection cable and load cell cables on the yellow
terminal. The terminal is connected with the housing via overvoltage conductors.
Connect the screens on the other side of the connection cable with the equipotential
bonding terminal of the downstream device (see instrument manual) as described in
Chapters
and
Note:
If hum interference occurs, the cable screens should only be connected on one side.
Depending on the design of the cable junction box used, either the jumper J3 must be
removed or the cable screens must be disconnected from the terminal contacts
highlighted in yellow.
WARNING
When installing in potentially explosive atmospheres:
It is imperative that you follow the application-dependent installation instructions!
Always check whether it is permissible to bilaterally connect the screens to the
equipotential bonding.
If necessary, remove jumper J3.
Note:
The calibration certificate, installation manual and data sheet of the load cell contain
information about how to connect the load cell cable screen with the load cell housing.
5.2 Connecting cables
To connect the junction box to the device, connection cable PR 6135/..or PR 6136/.. (for Ex
zone) must be used; max. length: 300 m.
