3. To prevent injury, note the following 
CAUTION
Only the voltage specified in the Instruction Manual should be applied to each terminal. Otherwise, a 
burst, damage, etc. may occur. 
Connect cables to the correct terminals. Otherwise, a burst, damage, etc. may occur. 
Ensure that polarity (+/-) is correct. Otherwise, a burst, damage, etc. may occur. 
The servo amplifier heat sink, regenerative resistor, servo motor, etc. may be hot while power is on or for 
some time after power-off. Take safety measures, e.g. provide covers, to prevent accidental contact of 
hands and parts (cables, etc.) with them. 
 
 
4. Additional instructions 
The following instructions should also be fully noted. Incorrect handling may cause a fault, injury, electric 
shock, etc. 
 
(1) Transportation and installation

Install the servo amplifier and the servo motor in a load-bearing place in accordance with the Instruction 
Manual. 
Do not get on or put heavy load on the equipment. 
The equipment must be installed in the specified direction. 
Leave specified clearances between the servo amplifier and the cabinet walls or other equipment. 
Do not install or operate the servo amplifier and servo motor which have been damaged or have any 
parts missing. 
Do not block the intake and exhaust areas of the servo amplifier. Otherwise, it may cause a malfunction.

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.
