Location and installation
Operating Environment
The environmental conditions of the installation location for SHA series actuators must be as follows.
Select an appropriate installation location and observe these conditions without fail.
◆
Operating temperature:
0 to 40
℃
The temperature in the cabinet may be higher than the atmosphere depending on
the power loss of housed devices and size of the cabinet. Plan the cabinet size,
cooling system, and device locations so the ambient temperature of the actuator is
kept 40
℃
or below.
◆
Operating humidity:
Relative humidity of 20 to 80%.
Make sure no condensation occurs. Take note that condensation is likely to occur in
a place where there is a large temperature change between day and night or when
the actuator is started/stopped frequently.
◆
Vibration:
25 m/s
2
(10 to 400Hz) or less (Refer to [1-13 Vibration resistance ] (P52))
◆
Impact:
300 m/s
2
or less (Refer to [1-12 Shock resistance] (P51))
◆
Use environment:
Free from condensation, metal powder, corrosive gases, water, oil mist, flammable
gases, etc.
◆
Protection class:
Standard products are structurally designed to meet the
IP-54 requirements.
However, rotating and sliding areas (oil seal areas) and connectors of SHA20, 25, 32 and 40 are
not IP-54-compliant.
Connectors of SHA58 and 65 are protected in fitted conditions.
◆
Locate the driver indoors or within an enclosure. Do not expose it to the sunlight.
◆
Altitude: lower than 1,000 m above sea level
◆
The oil seals in rotating and sliding areas do not fully prevent leakage of lubricant. If the actuator is used in a
clean room, etc., provide additional oil leakage prevention measures.
The protection class against contact and entry of foreign
matter is as follows:
5:
Protected against entry of dust/dirt. Entry of water or
foreign matter caused by incomplete protection must not
affect the operation of the system.
The protection class against water entry is as follows:
4:
Protected against water splashed from all directions.
