Electrical equipment

Use special caution when using these devices. They should be used in accordance with the instructions in the operating manual.
The central unit and other devices should be set up so that nothing hinders reaching them.
The cables should be orderly placed. They should not lie in the passages, so that no one would stand on them.
The plugs should be firmly pressed into the correct sockets in the computer devices. Each type of peripheral device has its own type of plugplug and socketsocket, so recognizing the right connectionconnection is not difficult.
The central unit should be positioned so that the air flow is correct. Otherwise, the elements responsible for cooling its interior will not be able to maintain the right temperature.
