2-1  Receiving Inspection 

Check the following when products are received. 

  Inspection procedure 

(1)  Check  the  shipping  container  and  item  for  any  damage  that  may  have  been  caused  during 

transportation.    If  the  item  is  damaged,  immediately  report  the  damage  to  the  dealer  it  was 
purchased from. 

(2)  A label is attached on the right side of the RSF-B mini series actuator.    Confirm the products you 

ordered by comparing with the model on the [TYPE] line of the label.    If it is different, immediately 
contact the dealer it was purchased from. 

 

The model code is interpreted as follows: 

 

 

 

 

 

 

 

 
 

 

For details of model symbols, refer to “1-2 Models” on page 2. 

 

(3)  The model code of the RSF-B mini series actuator to be driven is indicated on the [ADJUSTED 

FOR USE WITH] line of the driver label.    Match the actuator with its driver so as not to confuse 
the item with the other actuators. 

 

 

 

 

 

 

(4)  The [INPUT VOL.] line of the driver label indicates the power supply voltage value to be input to 

the driver. 

The value 24 means 24VDC power supply. 

If  the  power  supply  voltage  written  on  the  label  differs  from  the  power  supply  voltage  to  be 
connected to, immediately contact the dealer it was purchased from. 

 

 

 

 

 

Only connect the actuator specified on the driver label. 

The  drivers  have  been  tuned  for  the  actuator  specified  on  the  driver  label.  Wrong 
combination  of  “drivers”  and  “actuators”  may  cause  low  torque  problems  or  over 
current that may cause physical injury and fire. 

WARNING 

Do not connect a supply voltage other than the voltage specified 
on the label. 

The  wrong  power  supply  voltage  from  those  written  on  the  label  may  damage  the 
driver resulting physical injury and fire.
