2. Electric actuators / Common precautions
2.1 Wiring/Cables
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. Use only the specified cables.
3. Never connect or disconnect the cable or connector with the power on.
Caution
1. Wiring should be done correctly.
For each terminal, voltages other than those stipulated in the operation manual should not be
applied.
2. Connect the connector securely.
Check for correct connector wiring and polarity.
3. Handling noise
If the noise is at the same wavelength as the signal lines, it will lead to malfunction. As a
countermeasure, separate the high and low electrical lines, shorten the length of wiring, 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 interfer- ence 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. Be careful that cables are not caught by actuator movement.
6. Operate with cables such that they are not easily moved.
Avoid bending cables at sharp angles where they enter the product.
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. Do not move cables connected to the actuator.
The motor and lock cables are not robotic cables and can be broken when moved. Therefore,
secure the cables and the connectors (part “A” in the figure below) in place during set up.
9.
Select a “robotic cable (flexible cable)” when repeated bending of the actuator cable is
required. Also, do not put cables into a flexible moving tube with a radius smaller than the
specified value (50 mm or longer).
Electric shock, wire breakage, contact
failure, or a loss of product control may occur if “standard
cables” are used for repeated bend- ing.
10. Confirm wiring insulation.
