The Rittal cabinet principle
Rittal is a Germany company that specializes in the manufacture of all kinds of cabinets. It is famous for its reasonable design and guaranteed quality. Now there are many imitations in China, and imitation Rittal is also popular.
The working principle of the Rittal cabinet is to cut off the impulse current by the current carrying capacity of the wire itself, and the thin wire in the power protector of the cabinet with the motor box is not sensitive to the continuous small current it accumulates, but is sensitive to the instantaneous large impact, thus avoiding the phenomenon of burning out the wire due to excessive current.
With the continuous progress of science and technology, many products are constantly being upgraded, and technology is constantly upgrading, of course, Jinan chassis cabinets are no exception. Chassis cabinet suppliers have recently launched a new type of distribution box, distribution cabinet, which has the function of automatically cutting off power when encountering a crisis signal, which reduces the occurrence of some accidents.
How to use Rittal cabinets
Rittal cabinet can be divided into three series from the structure, ES cabinet (five-fold profile cabinet), PS cabinet (nine-fold profile cabinet), TS cabinet (sixteen-fold profile cabinet), the biggest feature is that the Rittal cabinet is the selection of profile structure structure, the structure of the cabinet is welded first, and then the top plate, bottom plate, side panel, door panel, device plate are fixed on the structure with screws, such an advantage is the modular structure of the product, easy to use;
1. Start to tie the cable tie with a cable tie where the root of the cable begins to be exposed, and if there are too many cables, the number of the network cable will be divided into two or more parts from the middle
, but it is necessary to ensure that each part of the network cable is continuous, because then the next step is easy to carry out.
2. Tie most of the network cables according to the needs and start to use the wiring board to manage the wiring, and the use of the wiring board is to remove the cable from the wiring according to an agreement
The back of the board passes through the distribution board, and the back of the distribution board is tied up with two continuous network cables, and each two are tied together.
There is a dislocation required, that is, not too many tie side by side, it is best to have a little distance between the top and bottom of each two cable ties, and start after the two ties are tied up in a row
Six network cables - tied together, on average every half a meter need to be re-tied, pay attention to the neatness when tying, do not tie together to give people discord
Harmonious feelings.
3. Use the cable management board to move down all the way, and wrap the back of the cable management board with a cable tie (half a meter a tie). The last six are at the end of the offline cable about one meter, and after they are tied, they start to tie two at a distance nearby, of course, they are tied in order. After every two roots are tied, use the same method to tie them again about half a meter down, which is conducive to the next step to hit the distribution frame.
4. The following is to start the distribution frame, because the above work has been done after the cable has been very clear, throw the cable to the outside of the cabinet and start to place it on a workbench in a group of three to start the work of crimping. If you crimp the line in a pre-arranged position, you will not be able to make mistakes.
5. Test the patch panel, test the cabinet by installation, if you find that there is no point to pass the point carefully check the contact and line sequence of the network cable and the module, and strive to pass all the subs, start to install the cabinet after the test module is pressed, and bind the network cable according to the original plan after installation, so as to be neat and beautiful, horizontal and vertical. The connectivity of each point is recorded, and if it is consistently unpassable, it needs to be recorded in the notes log. Convenient for subsequent viewing.
