2.4.1 Ferrite

In order to meet certain electrical noise emission limits and to protect the terminal from external influences, it is
necessary to install a ferrite core on the analog, IDNet and SICSpro load cell cable of the harsh enclosures. The
ferrite core is included with the terminal.
To install the ferrite, after routing the load cell cable through the gland on the rear housing, insert the cable
through the center of the core and then take one wrap around the outside of the core and route the cable
through 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 and on the inside of the enclosure.
Figure 11: Wrapping Complete Cable or Individual Wires through the Ferrite
Install the ferrite core (2) as close to the enclosure as possible and on the inside of the enclosure. An adhesive
brick (1) is provided to fix the ferrite core onto the enclosure. The adhesive brick has already been installed at
METTLER TOLEDO factory. In case it needs to be replaced in the installation field, follow the distance
requirement as shown in the drawing below.
