6.1 General information
- Protect the cable ends against contamination. Moisture must not get into the open
end of the cable.
- Do not shorten the load cell connecting cable. Connect the prepared cable end and
roll up the remaining cable.
- The screen of the load cell cable and the screen of the connecting cable must not be
connected inside the cable junction box if connection of both ends is not permissible
according to the regulations for installation in the explosion-prone area.
- Keep the load cell cables away from power cables.
- The distance between measurement cables and power cables and/or components
under high voltage should be at least 1 m (reference value).
- We recommend laying the load cell cables in separate cable trays or armored steel
pipes.
- Power cables should be crossed at right angles while taking into account the
minimum distance of 1 m (reference value).
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.
