Installation
1.2.3 Panel mount scale interface cable installation
The ZM401 & ZM405 Panel Mount assemblies include the AWT25-501388 Ferrite.
Installing the Ferrite on the Scale Interface Cable on the Panel Mount models assists
with eliminating potential noise captured by the scale interface cable.
Attach the ferrite onto the scale interface cable by wrapping the unshielded wires once
around the ferrite as shown below. Leave the Shield drain wire outside the ferrite and
connect to the SHLD connection on the terminal block, as shown in the photos below.
The optional 2nd Scale Input 5VDC & 10VDC Excitation Modules also include the
AWT25-501388 Ferrite for use on the ZM401 & ZM405 Panel Mount Models. The
Ferrites are not needed on the stainless steel desktop models as the Shield of the
Scale Interface cable terminates directly to the studs on the bottom of the enclosure.
