    (Always read these instructions before using the equipment.) Do not attempt to install, operate, maintain or inspect the servo amplifier and servo motor until you have read through this Instruction Manual, Installation guide, Servo motor Instruction Manual and appended documents carefully and can use the equipment correctly.
  • Page 3 1. To prevent electric shock, note the following: Before wiring or inspection, switch power off and wait for more than 10 minutes. Then, confirm the voltage is safe with voltage tester. Otherwise, you may get an electric shock. Connect the servo amplifier and servo motor to ground. Any person who is involved in wiring and inspection should be fully competent to do the work.
  • Page 4 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 Transport the products correctly according to their weights. Stacking in excess of the specified number of products is not allowed. Do not carry the servo motor by the cables, shaft or encoder.
