When using in places where water droplets are dropping, please use it on the 
basis  of  confirming  the  protection  level  of  servo  motor.  (except  for  the 
shaft-through  part)  When  oil  droplets  will  drip  into  the  shaft-through  part, 
please specify the servo motor with oil seal. 
Conditions for use of servo motors with oil seals: 
◆Make sure the oil level is below the lip of the oil seal when using. 
◆Please use the oil seal to keep the splash of oil droplets in good condition. 
◆When the servo motor is installed vertically upward, please pay attention not 
to oil accumulation on the lip of the oil seal. 
◆  Do  not  "bend"  or  apply  "tension"  to  the  wire,  especially  the  core  of  the 
signal line is 0.2mm or 0.3mm, very thin, so when wiring (using), do not make 
it too tight. 
 
 
 
Processing  of 
Connector Part 
For the connector part, please pay attention to the following items: 
◆When connecting the connector, please make sure that there is no foreign 
matter such as garbage or metal sheets in the connector. 
◆When connecting the connector to the servo motor, it is necessary to connect 
the connector from the side of the main circuit cable of the servo motor first, and 
the grounding wire of the main cable must be connected reliably. If one side of 
the encoder cable is connected first, the encoder may fail due to the potential 
difference between PE. 
◆When wiring, please make sure that the pins are arranged correctly. 
◆Connectors are made of resin. Do not apply shock to avoid damaging the 
connector. 
◆When carrying out the operation under the condition that the cable remains 
connected, it is necessary to grasp the main body of the servo motor. If only the 
cable is seized for handling, it may damage the connector or pull the cable off. 
◆If bending cable is used, full attention should be paid to the wiring operation 
and stress should not be applied to the connector part. If the stress is applied to 
the connector part, the connector may be damaged. 
 
2.2.3 Installation environment 
  Do not use this product near corrosive and flammable gas environments such as hydrogen sulfide, 
chlorine, ammonia, sulfur, chlorinated gas, acid, alkali, salt, etc. 
  In places with grinding fluid, oil mist, iron powder, cutting, etc., please choose motor with oil seal. 
  A place away from heat sources such as stoves; 
  Do not use motor in enclosed environment. Closed environment will lead to high temperature and 
shorten service life of motor.
