5.3 Notes on Wiring
Notes on Instrumentation-Converter Wiring
• To avoid 2-point grounding, ground the shield of output cable basically at the receiving side.
• Use a grounding wire of IV wire 5.5mm
2 or more. The size of the external grounding terminal screws is M4.
Do not share a grounding wire with other instruments where grounding current may flow. (An
independent grounding is preferable.)
• Power cable
When a 3-core cable is used: Ground with the FG terminal.
When a 2-core cable is used: Use an external grounding terminal and make the cable as short as possible.
