Cabinet Mounted Inverters (see
Figure A-2)
Mounting Instructions
If frequency inverters are mounted in a cabinet, the following rules must be observed:
•
The filters must be screwed directly to the panel with the largest possible contact area.
•
The support panel for the converters and filters must be a conductive steel sheet, with a common
ground busbar at the bottom. This ground busbar, mounted in front of the terminals, must be solidly
connected to the panel, ensuring good conductivity.
•
All cable screens, entering the cabinet, must be connected to the control cabinets ground busbar.
To ensure that the screen of the individual cable is connected solidly and with good conductivity to
the ground busbar, galvanized cable brackets as shown in Figure A-2 are recommended. This
applies also for coaxial cable, at which only the outer insulation should be removed.
Wiring Instruction for Cabinet Mounted Inverters
•
The connections between filter and inverter should be as short as possible!!
These conductors must be bound together (with tie wrap) forming a triangle in cross section.
•
Power and signal leads inside the cabinet must be physically distanced.
