Provide an adequate protection to prevent screws and other conductive matter, oil 
and other combustible matter from entering the servo amplifier. 
Do not block the intake and exhaust areas of the servo amplifier. Otherwise, it 
may cause a malfunction. 
Do not drop or strike the servo amplifier. Isolate it from all impact loads. 
Do not install or operate the servo amplifier which have been damaged or have 
any parts missing. 
When the equipment has been stored for an extended period of time, contact your

corners of the servo amplifier. 
The servo amplifier must be installed in the metal cabinet. 
When fumigants that contain halogen materials such as fluorine, chlorine, 
bromine, and iodine are used for disinfecting and protecting wooden packaging 
from insects, they cause malfunction when entering our products. Please take 
necessary precautions to ensure that remaining materials from fumigant do not 
enter our products, or treat packaging with methods other than fumigation (heat 
method). Additionally, disinfect and protect wood from insects before packing 
products.
