2.3 Safety Precautions
 WARNING
HIGH VOLTAGE
Drives contain high voltage when connected to AC mains input, DC supply, load sharing, or permanent
motors. Failure to use qualified personnel to install, start up, and maintain the drive can result in death or
serious injury.
l Only qualified personnel must install, start up, and maintain the drive.
l Before performing any service or repair work, use an appropriate voltage measuring device to make sure
that there is no remaining voltage on the drive.
 WARNING
UNINTENDED START
When the drive is connected to AC mains, DC supply, or load sharing, the motor may start at any time.
Unintended start during programming, service, or repair work can result in death, serious injury, or property
damage. Start the motor with an external switch, a fieldbus command, an input reference signal from the local
control panel (LCP), via remote operation using MCT 10 software, or after a cleared fault condition.
l Disconnect the drive from the mains.
l Press [Off/Reset] on the LCP before programming parameters.
l Ensure that the drive is fully wired and assembled when it is connected to AC mains, DC supply, or load
sharing.
 WARNING
DISCHARGE TIME
The drive contains DC-link capacitors, which can remain charged even when the drive is not powered. High
voltage can be present even when the warning indicator lights are off.
Failure to wait the specified time after power has been removed before performing service or repair work
could result in death or serious injury.
l Stop the motor.
l Disconnect AC mains, permanent magnet type motors, and remote DC-link supplies, including battery
back-ups, UPS, and DC-link connections to other drives.
l Wait for the capacitors to discharge fully. The minimum waiting time is specified in the table Discharge
time and is also visible on the nameplate on the top of the drive.
l Before performing any service or repair work, use an appropriate voltage measuring device to make sure
that the capacitors are fully discharged.
