During power-on or operation, do not open the front cover of the servo amplifier. You may get 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 or periodic inspection, do not remove the front cover even of the servo amplifier if the
power is off. The servo amplifier is charged and you may get an electric shock.
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 a fire.
Always connect a magnetic contactor (MC) between the main circuit power supply and L1, L2, and L3of
the servo amplifier, and configure the wiring to be able to shut down the power supply on the side of the
servo amplifier’s power supply. If a magnetic contactor (MC) is not connected, continuous flow of a large
current may cause a fire when the servo amplifier malfunctions.
When a regenerative resistor is used, use an alarm signal to switch main power off. Otherwise, a
regenerative transistor fault or the like may overheat the regenerative resistor, causing a fire.
3. To prevent injury, note the follow
CAUTION
Only the voltage specified in the Instruction Manual should be applied to each terminal, Otherwise, a
burst, damage, etc. may occur.
Connect the terminals correctly to prevent a burst, damage, etc.
