1. To prevent electric shock, note the following:
CAUTION
Before wiring or inspection, switch power off and wait for more than 20 minutes. Then, confirm the voltage
is safe with voltage tester. Otherwise, you may get an electric shock.
Connect the Converter unit 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 converter unit 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 converter unit and the servo amplifier.
You may get an electric shock.
Do not operate the Converter unit and 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 if the power is off.
The Converter unit is charged and you may get an electric shock.
2. To prevent fire, note the following:
CAUTION
Do not install the converter unit and regenerative brake resistor on or near combustibles.
Otherwise a fire may cause.
When the converter unit has become faulty, switch off the main converter unit 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.
