Chapter 3    Installing the actuator 

RSF-super_V1_02

- 25 - 

3-3  Location and installation 

3-3-1  Environment of location 

The environmental conditions of the location for RSF supermini series actuators must be as follows.   

  Service temperature:  0°C to 40°C

When  the  actuator  is  installed  in  a  closed  space,  the  temperature  in  the 
space may be higher than the atmosphere because of heat emission by the 
actuator.    Design  the  closed  space  size,  ventilation  system,  and  device 
locations so the ambient temperature near the actuator is always less than 
40°C.

  Service humidity: 

20 to 80% relative humidity, without condensation 
Make sure no water condensation occurs at the place where there is a large 
temperature change in a day or due to frequent heat-and-cool cycles due to 
the operation of the actuator. 

  Vibration: 

less than 49m/sec

2

 (10Hz~400Hz) 

  Impact: 

less than 300 m/sec

2

  Make sure the actuator is in an area free from: dust, water condensation, metal powder, corrosive 

gas, water, water drops, and oil mist. 

  Locate the driver indoors. Do not expose it to the sunlight. 

3-3-2  Considerations into External Noise 

Pay sufficient attention when installing the actuator: The actuator may malfunction by external noise 
depending on the conditions of installation. 

  Make sure that the FG line of RSF-5A is securely grounded. 
  Because  RSF-3B  does  not  have  any  FG  line  from  the  motor  enclosure.    Thus,  when  using  it, 

make sure that that enclosure is securely grounded to the body of the equipment through the gear 
head house.    In addition, make sure that the body of the equipment is securely grounded. 

  Do not bind the motor line and encoder signal line together. 
  Do not draw any external power line (i.e., driver power supply line, 100/200 VAC line.), actuator 

signal line, and motor line through the same pipe or duct or bind them together. 

The noise tolerance values of RSF supermini equipment are listed below. 
They  are  guide  values  from  a  measurement  that  were  performed  using  a  standard  relay  cable  in  a 
noise test environment while the clamp filter included with the product was installed to the equipment.  
Note that the noise tolerance values in your actual environment of use may differ from them.
