1. To prevent electric shock, note the following:
WARNING
Before wiring or inspection, turn off the power and wait for 15 minutes or more until the charg e lamp turns
off. Then, confirm that the voltage between P a nd N is safe with a voltage tester and others. Otherwise, an
electric shock may occur. In addition, always co nfirm from the front of the servo amplifier, whether the
charge lamp is off or not.
Connect the servo amplifier and servo motor to ground.
Any person who is involved in wiring and inspection should be ful ly competent to do the work.
Do not attempt to wire the servo amplifier and s ervo motor until they have been installed. Ot herwise, you
may get an electric shock.
Operate the switches with dry hand to prevent an e lectric shock.
The cables should not be damaged, stressed, loaded, or pinched. Otherwise, you may get an electric shock.
During power-on or operation, do not open the f ront cover of the servo amplifier. You may get an electric
shock.
Do not operate the servo amplifier with the fron t cover removed. High-voltage terminals and c harging 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 r egenerative resistor on incombustible material . Installing them
directly or close to combustibles will lead to a fire.
Always connect a magnetic contactor (MC) betwe en the main circuit power supply and L1, L2, and L3 of
the servo amplifier, and configure the wirin g 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 l arge
current may cause a fire when the servo am plifier malfunctions.
When a regenerative resistor is used, use an alarm signal to switch main power off. Oth erwise, a
regenerative transistor fault or the like may ov erheat 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 b urst, damage, etc.
Ensure that polarity ( , ) is correct. Otherwise, a burst, damage, etc. may occur.
Take safety measures, e.g. provide covers, to pre vent accidental contact of hands and parts (cables, e tc.)
with the servo amplifier heat sink, regenerative resistor, ser vo motor, etc. since they may be hot while
power is on or for some time after power-off. Their tem peratures may be high and you may get burnt or a
parts may damaged.
During operation, never touch the rotating parts of the servo motor. Doing so can cause injur y.
