Installation checklist65Installation checklistChecklistCheck the mechanical and electrical installation of the drive before start-up. Gothrough the checklist below together with another person. Read the Safetyinstructions on the first pages of this manual before you work on the unit.CheckMECHANICAL INSTALLATIONThe ambient operating conditions are allowable. (See Mechanical installation, Technical data:Ratings, Ambient conditions.)The unit is fastened properly to the cabinet. (See Planning the cabinet assembly andMechanical installation.)The cooling air will flow freely.The motor and the driven equipment are ready for start. (See Planning the electricalinstallation, Technical data: Motor connection.)ELECTRICAL INSTALLATION (See Planning the electrical installation, Electrical installation.)The internal EMC filter is disconnected if the drive is connected to an IT (ungrounded) orcorner-grounded supply network.The capacitors are reformed if stored over one year (ask local ABB representative for moreinformation).The drive is grounded properly.The supply (input power) voltage matches the drive nominal input voltage.The supply (input power) is connected to U1/V1/W1 (UDC+/UDC- in case of a DC supply)and the terminals are tightened to specified torque.Appropriate supply (input power) fuses and disconnector are installed.The motor is connected to U2/V2/W2, and the terminals are tightened to specified torque.The braking resistor (if present) is connected to R+/R-, and the terminals are tightened tospecified torque.The motor cable (and braking resistor cable, if present) is routed away from other cables.There are no power factor compensation capacitors in the motor cable.The external control connections to the JCU Control Unit are OK.There are no tools, foreign objects or dust from drilling inside the drive.
