Service and maintenance
• Ensure when doing this that you do not bend the cooling fins.
If the dirt sticks firmly then you should have the cleaning done by specialists.
Attention! Solvents and liquids can affect the proper functioning and safety of the
cooler.
We recommend the use of the cooling manager.
The cooling manager switches the SPEED COOLER on and off automatically as required.
• It is then impossible to forget to switch the Speed Cooler on and off.
• The running time of the Speed Cooler is reduced.
• The service intervals can be extended.
• The life of the Speed Cooler is lengthened.
7.2 Maintenance
The POWER CLAMP and SPEED COOLER devices need virtually no maintenance apart from
cleaning.
7.2.1 Checking electrical safety
When a skilled electrician is checking the electrical safety, note any peculiarities that result from
the mains filter switching that is used.
• The filter is switched before the mains switch directly at the power supply.
• In addition to capacitative and inductive elements the filter also has multiple discharge resis-
tances. The components in the filter are in X- and Y-switching form.
The filter has a direct influence on the measurement of the insulation resistance and the leakage
current.
• When checking the insulation, compare the measured values with the mains switched switched
on and off. The insulation resistance may not be less in the On position than in the Off position.
• When measuring the leakage current (protective earth conductor current) the current peak must
be noted when the mains power is switched on. If the test unit switches the mains current with-
out clipping the peaks, then under certain circumstances this can lead to the protective devices
triggering.
• The alternative of "substitute leakage current measurement" cannot be used.
We have intentionally not given any details here regarding nominal values, since they depend
on the test device or measuring procedure being used and can lead to misinterpretations.
7.2.2 POWER CLAMP
• Visual inspection of the housing for damage, cracks and deformation
• Visual inspection of the inside wall of the induction coil for melted points
Caution: If the insulating layer has melted this can expose live parts!
• Visual inspection of the adjusting segments and the stop elements of the induction coil for dam-
age, cracks, deformation
• Visual inspection of the connection plug, pins and insulating hose of the induction coil for dam-
age, cracks, deformation
• Visual inspection of all electrical cables for damage
