1. To prevent electric shock, note the following:
WARNING
Before wiring or inspection, switch power off and wait for more than 15 minutes. Then, confirm the voltage
is safe with voltage tester. Otherwise, you may get an electric shock.
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 amplifier and servo motor until they have been installed. Otherwise, you
may get an electric shock.
Operate the switches with dry hand to prevent an electric 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 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
Do not install the servo amplifier, servo motor and regenerative brake resistor on or near combustibles.
Otherwise a fire may cause.
When the servo amplifier has become faulty, switch off the main servo amplifier power side. Continuous
flow of a large current may cause a fire.
When a regenerative brake resistor is used, use an alarm signal to switch main power off. Otherwise, a
regenerative brake transistor fault or the like may overheat the regenerative brake 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.
Ensure that polarity ( , ) is correct. Otherwise, a burst, damage, etc. may occur.
Take safety measures, e.g. provide covers, to prevent accidental contact of hands and parts (cables, etc.)
with the servo amplifier heat sink, regenerative brake resistor, servo motor, etc.since they may be hot
while power is on or for some time after power-off. Their temperatures 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 injury.
