Caution
[CE-compliant products]
qEMC compliance was tested by combining the electric actuator LEF series and the controller
LEC series.
The EMC depends on the configuration of the customer’s control panel and the relationship with
other electrical equipment and wiring. Therefore conformity to the EMC directive cannot be
certified for SMC components incorporated into the customer’s equipment under actual
operating conditions. As a result it is necessary for the customer to verify conformity to the EMC
directive for the machinery and equipment as a whole.
wFor the servo motor (24 VDC) specification, EMC compliance was tested by installing a noise
filter set (LEC-NFA).
Refer to the WEB catalog for the noise filter set. Refer to the LECA Operation Manual for
installation.
[UL-compliant products]
When conformity to UL is required, the electric actuator and controller/driver should be used with a
UL1310 Class 2 power supply.
Series compatible with
secondary batteries
The actuator and controller/driver are sold as a package.
Confirm that the combination of the controller/driver and the actuator is correct.
<Check the following before use.>
q
Check the actuator label for model number (after "25A-"). This matches the controller/driver.
w Check Parallel I/O configuration matches (NPN or PNP).
* Refer to the operation manual for using the products. Please download it via our website, http://www.smcworld.com
