(2) Countermeasure example 2
If the noise from the control panel having the GOT adversely affects the GOT even after Countermeasure example 1
is taken, attach the ferrite core (KITAGAWA INDUSTRIES CO.,LTD. RFC-H13 or equivalent).
When attaching a ferrite core, insert the cable through the ferrite core several times (approximately three times).
When Countermeasure example 2-1 is difficult to be taken, such as the wiring is impossible, carry out wiring as
shown in Countermeasure example 2-2.
