Three phase 3-wire type : Example of ME96NSR (in case for direct input, wiring 3CT)
1. Use the shielded twisted pair cable.
2. To the units of both the end of link, the 120 ohm resistance has to be attached. This
instrument can perform a 120 ohm termination by short-circuiting the terminal of "T-"
Note
and "Ter".
3. The earth has to be connected to earth by a thick wire of low impedance.
4. Keep the distance between ModBus link to power line.
5. When the setting is 2CT, the use by 3CT wiring does not correctly measure for phase 2.
