1 Instruction for the Vacuum Unit preassembly[edit | edit source]
1.1 Preparation:[edit | edit source]
- Check if all drawings and documents are available, such as e-drawing, PI- diagramm, as well as the yellow cable markers and device stickers.
- Label and mark all electrical components with the yellow labes form Brückner. The PI diagram is very helpful for this. (You can find the PID in the printed folders of the mechanics or in the SAP.)
1.2 Cable pulling:[edit | edit source]
- All cables should be routed through the frame of the vacuum unit, run through the cable tray beneath the control cabinet, and enter the cabinet from the bottom.
- Start the cable pulling with the bigger power cables. Make sure the insulation gets not damaged during pulling the cables through the metal frames. (Sometimes the metal frames have some sharp edges.)
- Afterwards start with pulling the cables for the valves and sensors. Make sure that all data cables are not routed too close to the power cables.
1.3 Cable connecting:[edit | edit source]
The motor cables are servo cables with shielding. This shielding must be connected in the metal cable gland at the motors terminal box.
The cables will be connected in the +SEV11 control cabinet, which is mounted on the vacuum pump.
All shielded cables must be properly connected to the EMC rail. For this keep a look at the File:E-Montage-Kabelabfang+EMV-BMS-Guide-Line.pdf.
Label all cables on both ends (cabinet side and machine side) with the yellwo cable lables after connecting.
Close all cover sheets and clean the machine and cabinet.
Afterwards create a small photo documentation and upload the photos in the network "Q". (This is normally done by Felix Öllerer.)
=> Ready for commissioning and packaging.
