Electric Actuators / Common Preacautions - SMC Networks LE2R Series Operation Manual

When the actuator cable is to be bent repeatedly, do not route it in a movable wiring duct
⑨
smaller than the minimum specified radius (For cable lengths of 10 m or less: bend radius
= 50 mm minimum; For cable lengths of 15 m or more: bend radius = 75 mm minimum).
Repeated use of the cable with a bending radius less than the bending radius may cause electric
shock, cable breakage, poor contact, runaway, or other problems.
⑩ Confirm wiring insulation.
Poor insulation (interference with other circuits, poor insulation between terminals etc.) can apply
excessive voltage or current to the product causing damage.
⑪ The electric actuator speed and force may change depending on the cable length, load,
and mounting conditions.
Furthermore, if the cable length exceeds 5 m, then it will decrease by up to 10% for every
additional 5 m. (If cable length is 15m: Maximum 20% reduction.)
⑫ When checking the conductivity of the cable, be careful not to deform the connector's
mating hole and terminals.
Inserting a non-compatible connector, tool, cylinder-shaped object, etc., into the connector's
mating hole can cause the mating hole or terminals to become deformed, which may cause
contact failure or disconnection.
⑬ Refrain from plugging in and unplugging the connector frequently.
Doing so may result in contact failure or disconnection.
⑭ Do not connect wires while the power is ON.
It may cause the electric actuator or its peripheral devices to be damaged, causing a malfunction.

Caution
① Do not carry or swing the product by the cable or motor.
Electric Actuators / Common Precautions

■
Warning
① Be sure to read this Operation Manual（This manual and "Manifold Controller for Electric
Actuators / JXD1-M*"）.
Handling or operation other than that specified in this Operation Manual may lead to damage or
product failure.
Any damage attributed to use beyond the specifications is not guaranteed.
② There is a possibility of dangerous sudden action by the product if sliding parts of
machinery is twisted due to external forces etc.
In such cases, human injury may occur, such as by catching hands or feet in the machinery, or
damage to the machinery itself may occur. Design the machinery to avoid such dangers.
