Control Panel - Technical Guide 4 In the vast majority of cases, when electric installations and devices housed in control enclosures shut down or malfunction, the problem is thermal: excessively high or low temperature of electrical and, especially, electronic equipment. Uncontrolled external climatic conditions Internal heat balance not calculated Pollution and difficult or harsh environmental conditions High likelihood of a breakdown or malfunction of the installation Even the slightest shut-down or malfunction of the electrical installation can have major – even catastrophic – financial repercussions for a company, regardless of its business sector. Here are some examples of business sectors in which 1 hour of down time can be very expensive: 50 000 € 40 000 € 10 000 € 6 000 € 35 600 000 € 2 940 000 € 90 000 € 47 000 € 350 € Metalworking (foundry) Glassworks Motor industry Agri-business industry Microprocessor industry Banking transaction services Airline ticket-booking services Mobile telephone operators SMEs Malfunction of electrical installations Reasons Consequences Introduction Introduction

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
