(2) Grounding the ground cable
Manufacture the cable used with the GOT with the following method.
When manufacturing the cable, a ferrite core, cable clamp and cable shielding
material are required.
The cable clamp used by Mitsubishi Electric for the EMC specification
compatibility test is shown below.
•
TDK brand ZCAT3035-1330 Ferrite Core
•
TDK brand ZCAT2436-1330 Ferrite Core
