Fire as a result of inadequate installation
When installation is inadequate (failure to observe the cooling clearances or insufficient
distances from combustible objects), there is a risk of fire leading to death or serious injury.
• Maintain a cooling clearance of 7.9 inches (200 mm) on all sides of the braking resistor
• Maintain a sufficient distance from combustible objects.
Burns caused by hot braking resistor surfaces
During operation, the braking resistor can reach high temperatures and can cause burns if
touched.
• Allow the braking resistor to cool down before starting any work.
• Use the appropriate personnel protection equipment, e.g. gloves.
