Connection cable for analog load receptor

When laying scale connection cables (analog load receptors) please note:
S Only use suitable scale connection cable:
- The rated voltages of the connection cable must be observed.
- A double shielded cable is beneficial (shielding braid)
- The length and cross-section of the individual wires must meet the follow­
ing conditions:
Cable length (m) / cross-section (mm@) v270 (m/mm@)
- Maximum cable length between load cell and weighing terminal: 200m
S The shield of the load cell cable must be fitted across an extensive area in
the screwed cable gland of the weighing terminal. This can be done with all
WTX120 variants. We additionally offer a shield rail, both for industrial
applications and for applications subject to weights and measures legisla­
tion. The shield must in any case be installed in the immediate vicinity of the
WTX120 (a maximum of 7cm from the bottom edge of the WTX120 hous­
ing).
