A1. Ferrite installation
Weidos devices include a TRM-16-8-16E-WE Epoxy coated ferrite core, to act as a frequency high impedance
noise filter in hazardous environments.
Coated ferrite core has rounded corners to reduce load on cable and is made of Mn-Zn soft, epoxy coated.
The use of this ferrite for industrial uses is mandatory and necessary.

The mounting method of the ferrite included in the kit is as follows:
- In the wiring dedicated to the PLC power supply, the ferrite must be placed making 3 turns using the
negative pole
about
25 cm
from the PLC connector.
- The turns must be made to the ferrite following the instructions in the following image:
