 Before you perform any maintenance or inspection work, turn OFF the power supply, con-
firm that the CHARGE indicator on the front of the SERVOPACK has gone out, and then use
a tester to check the voltage between the positive and negative terminals on the SERVO-
PACK. Start inspection work only after you have confirmed that the main circuit voltage has
dropped.
If there is any main circuit voltage left, the risk of electric shock still exists. Do not touch the Ser-
vomotor or any wiring.
 All inspection and maintenance work must be performed by a trained technician.
Failure to observe this caution may result in electric shock or injury.
 Contact your Yaskawa representative for help with failures, repairs, or part replacement.
