Precautions for product specific

Precautions for wiring and cable
Warning
① Adjustment, installation, inspection, or wiring changes should be conducted after the
power supply to this product has been turned off.
Electrical shock, malfunction, or damage can result.
② Never disassemble the cable.
③ Never connect or disconnect the cable or connector with the power on.
Caution
① Wire the connector securely.
Do not apply any voltage to the terminals other than those specified in the Operation Manual.
② Wire the connector securely.
Check for correct connector wiring and polarity.
③ Take appropriate measures against noise.
Noise in a signal line may cause malfunction.
As a countermeasure, high voltage and low voltage cables should be separated, and keep
wiring lengths short, etc.
④ Do not connect power or high-voltage cables in the same wiring path as the unit.
The product can malfunction due to noise and surge voltage interference in the signal line from
power and high-voltage cables. Separate the wiring of the controller and its peripheral device
from that of power and high-voltage cables.
⑤ Take care that actuator movement does not damage cables.
⑥
Operate with cables secured.
Avoid bending cables at sharp angles where they enter the electric actuator.
⑦
Avoid twisting, folding, rotating, or applying external force to the cable.
Electric shock, wire breakage, contact failure, or a loss of product control may occur.
⑧
Fix the Communication cable for setting in place before using.
Communication cable for setting is not robotic type cable and can be damaged when moved.
⑨ Select "Robotic type cables" when deflecting power cable and I/O cable repeatedly.
Do not put cables into a flexible moving tube with a radius smaller than the specified
value (minimum 50mm).
Risk of electric shock, wire damage, contact failure and loss of control of the product can occur
if "Standard cables" are used in case of inflecting the cables repeatedly.
⑩ Confirm wiring insulation.
Poor insulation (interference with other circuits, poor insulation between terminals and etc.) can
apply excessive voltage or current to the product causing damage.
