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 char ge lamp turns
off. Then, confirm that the voltage be tween P and N is safe with a voltage tester and others. Otherwise, an
electric shock may occur. In additio n, always confirm from the front of the servo am plifier, 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 fully competent to do the work.
Do not attempt to wire the servo am plifier and servo motor until they have been inst alled. Otherwise, you
may get an electric shock.
Operate the switches with dry hand to prevent an electric shock .
The cables should not be dam aged, stressed, loaded, or pinched . Otherwise, you may get an electric shock.
During power-on or operation, do not open the front cover of the servo amplifier. Yo u may get an electric
shock.
Do not operate the servo amplifier wi th the front cover removed. High-voltage term inals and charging area
are exposed and you may get an electr ic shock.
Except for wiring or periodic inspec tion, do not remove the front cover even of the s ervo 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 m otor and regenerative resistor on incombustibl e 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 L3 of
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 m agnetic contactor (MC) is not connected, conti nuous flow of a large
current may cause a fire when the serv o amplifier malfunctions.
When a regenerative resistor is used , use an alarm signal to switch main power off . Otherwise, a
regenerative transistor fault or the lik e may overheat the regenerative resistor, causing a f ire.
3. To prevent injury, note the follow
CAUTION
Only the voltage specified in the I nstruction Manual should be applied to each terminal, Otherwise, a
burst, damage, etc. may occur.
Connect the terminals correctly to pre vent a burst, damage, etc.
Ensure that polarity ( , ) is correct. Otherwise, a burst, dam age, etc. may occur.
Take safety measures, e.g. provide co vers, to prevent accidental contact of hands and par ts (cables, etc.)
with the servo amplifier heat sink, re generative resistor, servo motor, etc.since the y may be hot while
power is on or for some time after po wer-off. Their temperatures may be high and you may get burnt or a
parts may damaged.
During operation, never touch the rotat ing parts of the servo motor. Doing so can cause injury.
