4.2.2 Connecting cables
1. European type terminal block
Use shielded twisted pair cables for connecting communication equipment operating in accordance with RS-
485.
The table below shows applicable cables and tightening torques.
With regard to the cable end treatment, use a stranded cable or solid cable as it is, or use a bar terminal with
insulating sleeve.
• When using a stranded cable or solid cable as it is
- Twist the end of a stranded cable so that wires do not get barbed.
- Do not plate the end of the cable.
• When using a bar terminal with insulating sleeve
Because it is difficult to insert a cable into an insulating sleeve
depending on the thickness of the cable sheath, select the proper cable
according to the outline drawing.
• Tool
- When tightening a terminal on the European terminal block, use a small commercial straight shape
screwdriver whose tip is shown in the figure to the right.
Note:
If the diameter of screwdriver grip is too small, tightening torque will
not be able to be achieved. Use the following recommended
screwdriver or an appropriate replacement (grip diameter:
approximately 25mm).
