1. To prevent electric shock, note the following

WARNING

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

turns off. Then, confirm that the voltage between P+ and N- is safe with a voltage tester and others.

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.

Do not operate switches with wet hands. Otherwise, it may cause an electric shock.

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

shock.

During power-on or operation, do not open the front cover of the servo amplifier. Otherwise, it may cause

an electric shock.

Do not operate the servo amplifier with the front cover removed. High-voltage terminals and charging

area are exposed and you may get an electric shock.

Except for wiring and periodic inspection, do not remove the front cover of the servo amplifier even if the

power is off. The servo amplifier is charged and you may get an electric shock.

To prevent an electric shock, always connect the protective earth (PE) terminal (marked ) of the servo

amplifier to the protective earth (PE) of the cabinet.

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

2. To prevent fire, note the following

CAUTION

Install the servo amplifier, servo motor, and regenerative resistor on incombustible material. Installing

them directly or close to combustibles will lead to smoke or a fire.

Always connect a magnetic contactor between the power supply and the main circuit power supply (L1,

L2, and L3) of the servo amplifier, in order to configure a circuit that shuts down the power supply on the

side of the servo amplifier’s power supply. If a magnetic contactor is not connected, continuous flow of a

large current may cause smoke or a fire when the servo amplifier malfunctions.

Always connect a molded-case circuit breaker, or a fuse to each servo amplifier between the power

supply and the main circuit power supply (L1, L2, and L3) of the servo amplifier, in order to configure a

circuit that shuts down the power supply on the side of the servo amplifier’s power supply. If a molded-

case circuit breaker or fuse is not connected, continuous flow of a large current may cause smoke or a

fire when the servo amplifier malfunctions.

When using the regenerative resistor, switch power off with the alarm signal. Otherwise, a regenerative

transistor malfunction or the like may overheat the regenerative resistor, causing smoke or a fire.

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

matter from entering the servo amplifier and servo motor.

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.

A - 3

CAUTION

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.
