ACS 300 User s Manual Chapter 3 Power Connections Insulation Checks ACS 300 to the mains Before proceeding with the insulation resistance measurements make sure that the ACS 300 is disconnected from the mains Failure to disconnect the mains could result in death or serious injury A Warning Insulation checks are to be done before connecting the Terminal Connections To connect the mains motor and control cables remove the front cover of the unit by loosening the two screws at the bottom The TEMP LIM parameter provides motor thermal protection If this feature is not used the motor connected to the ACS 300 requires overload protection in accordance with the National Electric Code U S A Connect the mains and motor cables according to the layout in figure 3 1 page 16 In case the shield is used also as a protective conductor you must connect it both to the clamp and to the PE terminal Clamping alone is insufficient Note In addition to clamping the motor cable screen to the clamping plate at the ACS 300 connect the screen to motor earth at the motor ACS 300 User s Manual 21 Chapter 3 Power Connections Earthing and earth faults 22 The ACS 300 must always be earthed through an earthing conductor connected to the earthing terminal PE Note Earth connection is essential before connecting supply because of high leakage current When the ACS 300 is not connected to the
