 Wiring and inspections must be performed only by qualified engineers.
There is a risk of electric shock or product failure.
 Wait for at least six minutes after turning OFF the power supply (with a SERVOPACK for a 100-
VAC input, wait for at least nine minutes) and then make sure that the CHARGE indicator is not
lit before starting wiring or inspection work. Do not touch the power supply terminals while the
CHARGE lamp is lit after turning OFF the power supply because high voltage may still remain in
the SERVOPACK.
There is a risk of electric shock.
 Troubleshooting Precautions
 The product may suddenly start to operate when the power supply is recovered after a momen-
tary power interruption. Design the machine to ensure human safety when operation restarts.
There is a risk of injury.
 When an alarm occurs, remove the cause of the alarm and ensure safety. Then reset the alarm
or turn the power supply OFF and ON again to restart operation.
There is a risk of injury or machine damage.
 If the Servo ON signal is input to the SERVOPACK and an alarm is reset, the Servomotor may
suddenly restart operation. Confirm that the servo is OFF and ensure safety before you reset an
alarm.
There is a risk of injury or machine damage.
 If there is the possibility that an external force (including gravity) may move the current position
and create a hazardous situation when power is interrupted or an error occurs, install an exter-
nal braking mechanism that ensures safety.
 Disposal Precautions
 When disposing of the product, treat it as ordinary industrial waste. However, local ordinances
and national laws must be observed. Implement all labeling and warnings as a final product as
required.
