SMC Networks LE2FS Series Operation Manual page 11

Caution
① Conduct the following inspection before operation.
a) Confirm that the power supply line and each signal line is not damaged.
b) No play or looseness of the connectors to each power line and signal line
c) No play or looseness of the mounting
d) Confirm that the electric actuator/cylinder/controller/driver is operating correctly.
e) Confirm the function of the emergency stop of the whole system.
② If several persons are to be working concurrently, determine the procedure, signs,
measures against abnormality, and restarting measures in advance. Then, have
someone else, supervise the work.
③ The product may operate at a speed different from the set speed depending on the load
and resistance.
When selecting a product, check the catalog for instructions regarding selection and specifications.
④ Do not apply a load, impact, or resistance in addition to the transferred load during the
return to origin.
If the product is made to return to origin by pushing force, a displacement of the origin position may
occur.
⑤ Do not remove the product name plate.
⑥ Operation tests should be carried out at a low speed. Start operation using a predefined
speed after confirming there are no problems.
⑦ Do not apply forces of impact, collision, or resistance to the moving parts of an actuator
during operation.
Doing so will cause a decrease in product life, damage to the product, etc.
【Grounding】
Warning
① Ensure that the product is grounded to allow the noise tolerance of the electric actuator.
Otherwise, it may cause an electric shock or fire.
② Dedicated grounding should be used.
Grounding should be to a D-class ground. (Ground resistance 100Ω or less)
③ The earth cable length should be as short as possible.
④ In the unlikely event that malfunction is caused by the ground connection, then it may
be disconnected.
⑤ Avoid common grounding points shared with other devices.
