Safety instructions
Chapter overview
WARNING! All electrical installation and maintenance work on the drive should
be carried out by qualified electricians only.
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 the 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 there is no voltage in the drive, control
cabling, motor, or motor cable you are working with.
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 the drive system connected to the permanent magnet motor.
For complete safety instructions, see the relevant drive manual. See
