1. To prevent electric shock, note the following:
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. You may get an electric shock.
Do not operate the converter unit and 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 if the power is off. The servo
amplifier is charged and you may get an electric shock.
2. To prevent fire, note the following:
Install the converter unit and servo amplifier, servo motor and regenerative resistor on incombustible
material. Installing them directly or close to combustibles will lead to a fire.
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 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
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 ( ,
During power-on or for some time after power-off, do not touch or close a parts (cable etc.) to the servo
amplifier heat sink, regenerative resistor, servo motor, etc. 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.
