Wiring for control circuit terminals
For models of FRN200F1S-4U to FRN350F1S-4U
Route the control circuit cable in keeping with the left side panel of the inverter as shown in Figure 2.28.
Fasten the control circuit cable to the cable tie support with a cable tie (insulation lock) as shown in Figure
2.28.
The hole in the cable tie support is 0.15 inch(3.8 mm) × 0.06 inch(1.5 mm) in size. To pass the cable tie
through the hole, it should be 0.15 inch(3.8 mm) or less in width and 0.06 inch(1.5 mm )or less in thickness.
Figure 2.28 Routing and Fastening the Control Circuit Cable
-
Route the wiring of the control terminals as far from the wiring of the main circuit as possible.
Otherwise electric noise may cause malfunctions.
-
Fix the control circuit wires inside the inverter to keep them away from the live parts of the main
circuit (such as the terminal block of the main circuit).
