Mounting the optional components

4.2.1

Mounting the external braking resistor

Risk of fire due to improper installation
Resistor surfaces reach high temperature during operation. A braking resistor which is not
properly mounted can cause components overheat with associated risk of fire.
• Mount the resistor on non-flammable and heat-resistant surfaces only.
• Ensure that there are no flammable or combustible objects or materials close to the resistor.
Risk of burn due to high surface temperature
The braking resistor can reach a temperature of 300 °C in normal operation. Ratings given are
absolute maximum and must not be exceeded. In the event of operation beyond specification
or a fault, the resistor can reach a temperature of up to 600 °C. You can get burnt when touching
the hot surface.
• Mount the resistor in such a way that it is not accessible and cannot be touched during
• Allow sufficient distance from nearby materials to keep them at an acceptable temperature.
• Ensure that ventilation is provided.
