Installation checklist and start-up103Close the auxiliary circuit On/Off switch (Q100) if present.Starting the supply unitClose the main switch/disconnector (Q1).Units with emergency stop: Turn the Start switch on the cabinet doorfrom 0 into START position for 2 seconds, then release the switch andleave it in position 1.Checks with the supply unit runningCheck the settings of the earth fault (ground fault) monitoring device (ifpresent).See chapter Electrical installation.Supply (line-side converter) program set-upParameters of the IGBT supply unit need not be set during the start-upprocedure, or in normal use. In case the parameters of the supply unitneed to be changed, switch the control panel (optional) to view the line-side converter as described in section Control panel on page 37.Alternatively, a PC equipped with a programming tool (e.g.DriveWindow) can be connected to channel CH3 of the inverter unit’sRDCU.Note: It is recommended to set parameter 16.15 I/O START MODE toDI2 LEVEL if• the motor is started and stopped frequently. This prolongs the life ofthe charging contactor,• the drive is equipped with the emergency stop option,• when it is required to start the motor without delay after the startcommand, or• if the drive is connected to a common DC bus. Otherwise thecharging resistors may be damaged.Note: The output voltage of the drive can be raised using a parametersetting; for example, it is possible to run a 500 V motor off a 400 Vsupply. Contact your local ABB representative for more information.Application program set-upFollow the instructions in the Firmware Manual of the inverter unit to startup the drive and to set the drive parameters.See the Firmware Manual of theinverter unit.On-load checksCheck that the Prevention of Unexpected Start function (if installed)works:• Start and Stop the drive and wait until the motor has stopped.• Open the Prevention of Unexpected Start switch (mounted on a controldesk).• Give a Start command. The drive should not start.• Reset the drive.Optional function. See deliveryspecific circuit diagrams.Check that the cooling fans rotate freely in the right direction, and the airflows upwards.Check visually that the fans rotate inthe direction indicated by an arrowon the fan housing.Check the direction of rotation of the motor.Check the correct operation of the emergency-stop circuits from eachoperating location.Action Additional information
