Ferrites
In order to meet certain electrical noise emission limits and to protect the IND560
from external influences, it is necessary to install a ferrite core on each cable
connected to the terminal. There are two ferrite cores included with the basic
terminal and additional ferrites are supplied with each of the options.
To install ferrites, 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 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 2-11.
Harsh Enclosure Cable Glands
The IND560 harsh environment terminal is designed to withstand severe
washdown environments. However, care must be taken when installing cables
and/or connectors that enter the terminal enclosure. To ensure a watertight seal:
•
Pass the cables through an appropriately sized cable grip before connecting
the wires. For example, the load cell cable goes through the cable gland next
to the AC power cord (see Figure 2-12).
