3.4.2 Common Precautions on Terminals for Control Circuit
■ Precautions on Wiring
·
For wiring of terminals of control circuit, strip specified length of insulation
coating before connecting.
·
Loosen the terminal screws and insert the wires from bottom of the terminal
block, and tighten the screws to specified tightening torque.
·
Twist the strands of stripped wires, avoiding length variance.
Also, do not solder them.
·
Any loose connection could cause wire to come off and lead to malfunction.
Also, over-tightening could cause short-circuit due to screws and the unit
broken, thus lead to malfunction.
·
Use shielded cables for all control signal lines and separate them from power
lines or high-voltage circuits (20 cm or more).
·
Wiring length of control signal lines should be within 30 m.
·
Since input signals of control circuit are feeble, use dedicated terminals for
feeble signals to avoid poor contact during contact input.
