The ACS550-02 /-U2 is a field repairable unit. In case of service or repair of malfunctioning unit, contact your local Authorized Service Centre for ! The acs550 will start up automatically after an input voltage interruption if the external run command is ! When the control terminals of two or more drive units are connected in parallel, the auxiliary voltage for these control connections must be taken from a single source which can either be one of the units or an external !

4 The heat sink may reach a high temperature, see Technical Data of Warnings and NotesThere are two types of safety instructions throughout this Manual : Notes draw attention to a particular condition or fact, or give information on a subject. Warnings caution you about conditions which can result in serious injury or death and/or damage to the equipment. They also tell you how to avoid the danger. The warning symbols are used as follows:Dangerous voltage warning warns of high voltage which can cause physical injury and/or damage to the equipment.

Ask ABB for the installation : Before Installation on page 21Te c h ni c al D ataCheck the insulation of the motor and the motor cable.

Operation is not allowed if the motor nominal voltage is less than 1/2 of the drive nominal input voltage, or the motor nominal current less than 1/6 of the drive nominal output the Motor Winding and BearingsThe output of the drive comprises regardless of output frequency pulses of approximately times the mains network voltage with a very short rise time.

10 This is the case with all Drives employing modern IGBT inverter technology. The voltage of the pulses can be almost double at the motor terminals, depending on the motor cable properties. This in turn can cause additional stress on the motor variable speed Drives with their fast rising voltage pulses and high switching frequencies can cause current pulses through the motor bearings which can gradually erode the bearing races. To avoid damage to motor bearings, insulated N-end (non-driven end) bearings and output filters from ABB are recommended according to the following table.
