• Remedy 1 (Refer to the figures Remedy 1-1 and 1-2 below.)
If the electric potential difference between the ground cable and the panel that houses the GOT is creating
problems, connect the ground cable to the panel also.
If the wiring method as shown in Remedy 1-1 is not feasible, follow Remedy 1-2.
If taking Remedy 1 worsens noise interference, taking Remedy 2 may alleviate it.
• Remedy 2 (Refer to the figures Remedy 2-1 and 2-2 below.)
Attach a ferrite core to the cable if noise from the GOT panel has adverse effects on the GOT when Remedy
1 is taken.
Wind the wire around the ferrite core several times (approx. 3 times), if a ferrite core is used.
If the wiring method as shown in Remedy 2-1 is not feasible, follow Remedy 2-2.
