Installing Load Cell Cable and Connectors
In order to meet certain electrical noise emission limits and to protect i-DT61PW and i-DT61XWE from external
influences, it is necessary to install a ferrite core on the load cell cable connected to the terminal. The ferrite
core is included with the terminal.
To install the ferrite, simply route the cable through the center of the core and then take one wrap around the
outside of the core and route the cable through the center again. Either the complete cable or the individual
wires can be wrapped through the ferrite. This should be done as close to the enclosure as possible. See
Figure 2-1.
