Checklist for commissioning chassis power sections
The following checklist must be carefully observed. Read the safety information in
the Equipment Manuals before starting work.
Table 2-3
The ambient conditions must be permissible. See Equipment Manuals.
The components must be properly installed in the cabinet units.
The air flow for the modules, which undergo forced cooling, must be
ensured. The ventilation clearances must be ensured. The air flow specified
in the technical specifications must be ensured. An air short-circuit must not
be allowed to form between the chassis air inlet and outlet on account of the
installation.
The ventilation clearances for the components must be observed.
The CompactFlash Card must be inserted in the Control Unit.
All necessary components of the configured drive line-up are installed and
available.
The DRIVE-CLiQ topology rules must be observed.
For information about DRIVE-CLiQ wiring, see Section 2.3.
The line-side and motor-side power cables must be dimensioned and routed
in accordance with the ambient and routing conditions. The maximum
permissible cable lengths between the converter and the motor must be
observed depending on the type of cables used.
The ground for the motor should be directly connected to the ground for the
Motor Module (short distance).
The cables must be properly connected with the correct torque to the
component terminals. The cables for the motor and low-voltage switchgear
must also be connected with the required torques.
The busbar/wiring for the DC connection between the infeed and the Motor
Modules must be checked with regard to the load and installation conditions.
When more than one motor is used, the total current of the DC connection
must be observed.
The cables between the low-voltage switchgear and the power section must
be protected with line fuses for conductor protection (VDE 636, Part 10).
Combined fuses are recommended for conductor and semi-conductor
protection (VDE 636, Part 40 / EN 60269-4). For information about the
relevant fuses, see the catalog.
Ensure that measures are taken to relieve strain on the cables.
