1. To prevent electric shock, note the following

Before wiring and inspections, turn off the power and wait for 15 minutes or more until the charge lamp

turns off. Otherwise, an electric shock may occur. In addition, when confirming whether the charge lamp

is off or not, always confirm it from the front of the servo amplifier.

Ground the servo amplifier and servo motor securely.

Any person who is involved in wiring and inspection should be fully competent to do the work.

Do not attempt to wire the servo amplifier and servo motor until they have been installed. Otherwise, it

may cause an electric shock.

The cables should not be damaged, stressed, loaded, or pinched. Otherwise, it may cause an electric

shock.

To avoid an electric shock, insulate the connections of the power supply terminals.

2. To prevent fire, note the following

Install the servo motor on incombustible material. Installing them directly or close to combustibles will

lead to smoke or a fire.

Provide an adequate protection to prevent screws and other conductive matter, oil and other combustible

matter from entering the servo motor.

3. To prevent injury, note the following

Only the power/signal specified in the Instruction Manual must be supplied/applied to each terminal.

Otherwise, an electric shock, fire, injury, 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 motor, etc. may be hot while power is on and for some time after power-off. Take safety

measures such as providing covers to avoid accidentally touching them by hands and parts such as

cables.

The surface temperature of the servo motor may exceed 100 ˚C depending on its mounting and

operating conditions.

During operation, never touch the rotor of the servo motor. Otherwise, it may cause injury.
