Power supply
Caution
① Use a power supply that has low noise between lines and between the power and
ground.
I
n cases where noise is high, an isolation transformer should be used.
② Use a power supply that has a capacity of not less than the maximum power specified
for the electric actuator input power supply.
If the power supply capacity is insufficient, voltage drop may occur during acceleration.
③ Appropriate measures should be taken to prevent lightning surges. Ground the surge
absorber for lightning separately from the grounding of the electric actuator and its
peripheral devices.
【Unpackaging】
Warning
① Check the received product is as ordered.
If a different product is installed from the one ordered, injury or damage can result.

Operating environment
Warning
① Avoid use in the following environments.
1. Locations where a large amount of dust and cutting chips are airborne.
2. Locations where the ambient temperature is outside the range of the temperature
specification (refer to specifications)
3. Locations where the ambient humidity is outside the range of the humidity specification (refer to
specifications).
4. Locations where corrosive gas, flammable gas, sea water, water and steam are present.
5. Locations where strong magnetic or electric fields are generated.
6. Locations where direct vibration or impact is applied to the product.
7. Areas that are exposed to splashes of water and oil drops.
8. Areas exposed to direct sunlight (ultraviolet rays).
9.Environment at an altitude of 1000 meters or higher.
Heat dissipation and withstand voltage will decrease. Contact SMC for details.
② Do not use in an environment where the product is directly exposed to liquid, such as
cutting oils.
If cutting oils, coolant or oil mist contaminates the product, failure or increased sliding resistance can
result.
③ Install a protective cover when the product is used in an environment directly exposed
to foreign matter such as dust, cutting chips and spatter.
Play or increased sliding resistance can result.
④ Shade the sunlight in the place where the product is applied with direct sunshine.
⑤ Shield the product if there is a heat source nearby.
When there is a heat source surrounding the product, the radiated heat from the heat source can
increase the temperature of the product beyond the operating temperature range.
⑥ Grease oil can be reduced due to the external environment and operating conditions.
The lubrication performance may deteriorate and shorten the life of the product.
