Notes related to emissions
In order to meet the emission specifications for the HG2G-5T, HG1G, attach a ferrite core to the power cables and
communication cables.
Recommended ferrite core: ZCAT3035-1330 manufactured by TDK Corporation
Attach the ferrite core near the
power supply section of the power
cables connected to the main unit.
