Cable reels The IP Code ("International Protection Code") is very important for the respective areas of application. This allows you to find out which operating conditions the cable reel is suitable for. What do the lights on the socket insert tell me? Why should you always unroll a cable reel completely? Our HEDI diagnosis system DiagS shows you at a glance whether the cable reel is ready for use. Why does the thermal protection switch trip? The thermal protection switch (red button on the socket insert) is a protective device that interrupts the circuit in case of overheating. It is triggered when a temperature limit value prescribed by standards is reached. Two small lights indicate the status of the cable reel: Green signal light is on: The cable reel is ready for operation Red and Green signal lights are on: The thermal protection switch has tripped. Operating voltage is still present. Energy distributors The wire gets hot when current flows through it. If the cable is not unwound, this heating of the individual cable windings adds up, which can lead to melting of the sheath and destruction of the cable reel in case of overload. Cables & Extension lines The highest level of safety is HEDI's claim. For outdoor use, the cable reel should always have a closed socket insert. A thermal protection switch for the cable reel is also an absolute standard. In addition, some HEDI cable reels have the unique HEDI diagnosis system DiagS, which shows at a glance whether the cable reel is ready for use and whether the operating voltage is present at the sockets. Does HEDI also manufacture cable reels with foreign plug-in systems? When the reel heats up, two influences act together. On the one Our standard range includes, of course, cable reels with all common hand, the cable heats up due to the current flow, and on the other foreign plug systems. These include the Swiss, British, and French or hand, the ambient temperature heats up the cable. At high ambi- Belgian plug-in system. ent temperatures, the thermal protection switch trips more quickly, even if the maximum load limit has not yet been reached. Warning: The thermal protection switch is a safety device and must not be removed or bridged. Otherwise, serious damage or even fire may occur. In the event of modifications of this kind, any liability on the part of the manufacturer shall lapse and the party which has caused the modifications shall be liable for all resulting damage. 69 Luminaires / Security and IP code Application note If the thermal protection switch has tripped, unwind the reel completely and let it cool down. You can then press the red thermal protection switch button on the socket insert deeply. The switch has a push-button function and jumps back automatically.
