Connecting cables
1. European type terminal block
The FX
3G
-485-BD-RJ terminal block is used for grounding.
The other options use shielded twisted pair cables for connecting communication equipment operating in
accordance with RS-485.
The table below shows applicable cables and tightening torques.
Do not tighten terminal screws with a torque outside the above-mentioned range.
Failure to do so may cause equipment failures or malfunctions.
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.

-485ADP cannot 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.
