IS300 Series Servo Drive User Manual Safety Information and Precautions
- 7 -
Use Stage Safety Grade Precautions
At wiring
WARNING
Never connect the power cables to the output terminals (U, V,
W) of the servo drive. Pay attention to the marks of the wiring
terminals and ensure correct wiring. Failure to comply will result
in damage to the servo drive.
Ensure that all wiring complies with the EMC requirements
and local safety standard. Use wire sizes recommended in the
manual. Failure to comply may result in accidents.
Never connect the braking resistor between the DC bus

Before
power-on
DANGER
Check that the following requirements are met:
- The voltage class of the power supply is consistent with the
rated voltage class of the servo drive.
- The input terminals (R, S, T) and output terminals (U, V, W)
are properly connected.
- No short-circuit exists in the peripheral circuit.
- The wiring is secured.
Failure to comply may result in damage to the servo drive
Cover the servo drive properly before power-on to prevent
electric shock.
WARNING
Do not perform the voltage resistance test on any part of the
servo drive because such test has been done in the factory.
Failure to comply may result in accidents.
All peripheral devices must be connected properly under the
instructions described in this manual. Failure to comply may
result in accidents.
After power-
on
DANGER
Do not open the cover of the servo drive after power-on. Failure
to comply may result in electric shock.
Do not touch the servo drive or peripheral circuit with wet hands.
Failure to comply may result in electric shock.
Do not touch any I/O terminal of the servo drive. Failure to
comply may result in electric shock.
The servo drive automatically performs safety detection on the
external strong power circuit immediately after power-on. Do not
touch the U, V, W terminals of the servo drive or wiring terminals
of the motor. Failure to comply may result in electric shock.
WARNING
Do not touch the rotating part of the motor during the motor
auto-tuning or running. Failure to comply may result in
accidents.
Do not change the default settings of the servo drive. Failure to
comply may result in damage to the servo drive.
