General safety
WARNING! If you ignore the safety instructions, injury or death can occur. If
you are not a qualified electrician, do not do electrical work.
• Never attempt to repair a malfunctioning drive; contact your local ABB
representative or Authorized Service Center for service support.
• Make sure that dust from drilling does not enter the drive during the installation.
Electrically conductive dust inside the drive may cause damage or lead to
malfunction.
• Ensure sufficient cooling.
Safe start-up and operation
These warnings are intended for all who plan the operation, start up or operate the
drive.
General safety
WARNING! If you ignore the safety instructions, injury or death can occur. If
you are not a qualified electrician, do not do electrical work.
• Before adjusting the drive and putting it into service, make sure that the motor and
all driven equipment are suitable for operation throughout the speed range
provided by the drive. The drive can be adjusted to operate the motor at speeds
above and below the speed provided by connecting the motor directly to the
power line.
• Do not activate automatic fault reset functions if dangerous situations can occur.
When activated, these functions will reset the drive and resume operation after a
fault.
• Do not control the drive with an AC contactor or disconnecting device
(disconnecting means); use the control panel start and stop keys and or
external commands (I/O or fieldbus). The maximum allowed number of charging
cycles of the DC capacitors (in other words, power-ups by applying power) is two
per minute and the maximum total number of chargings is 15,000.
Notes:
• If an external source for start command is selected and it is ON, the drive will start
immediately after an input voltage break or fault reset unless the drive is
configured for 3-wire (a pulse) start/stop.
• When the control location is not set to local (LOC not shown on the display), the
stop key on the control panel will not stop the drive. To stop the drive using the
control panel, first press the LOC/REM key and then the stop key .
