Safety instructions
Never work on the drive, the braking chopper circuit, the motor cable or the motor
when input power is applied to the drive. After disconnecting input power, always
wait for 5 minutes to let the intermediate circuit capacitors discharge before you
start working on the drive, control cabling, motor or motor cable. Even when input
power is not applied to the drive, externally supplied control circuits may carry
dangerous voltages. Always ensure by measuring that no voltage is actually
present.
A rotating permanent magnet motor can generate a dangerous voltage. Lock the
motor shaft mechanically before connecting a permanent magnet motor to the
drive, and before doing any work on a drive system connected to a permanent
magnet motor.
