Checklist
Check the mechanical and electrical installation of the drive before start-up. Go
through the checklist below together with another person. Read the
Safety
instructions on the first pages of this manual before you work on the unit.
Check
MECHANICAL INSTALLATION
The 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 and
Mechanical installation. )
The cooling air will flow freely.
The motor and the driven equipment are ready for start. (See Planning the electrical
installation, Technical data : Motor connection .)
ELECTRICAL INSTALLATION (See Planning the electrical installation, Electrical installation. )
The VAR (frames A and B) and EMC/VAR1/VAR2 (frames C and D) screws are removed if
the drive is connected to an IT (ungrounded) supply network.
The capacitors are reformed if stored over one year (ask local ABB representative for more
information).
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 to
specified 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.
