Installing Cables and Connectors
Information for installing cables and connectors for the T72XW indicator is provided in this section, including:




Wiring Connections for Options
In order to meet certain electrical noise emission limits and to protect the T72XW from external influences, it is
necessary to install a ferrite core on the load cell cable connected to the indicator. The ferrite core is included with
the basic indicator.
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 1-4.

Main Board Wiring Connections

board, as shown in Figure 1-5.
