CAUTION
Without temperature monitoring the resistor might get damaged.
WARNING
Risk of fire, severe personal and property damage
If an unsuitable braking resistor is used, this could result in a fire and severely damage,
people, property and equipment. It is essential that not only the correct braking resistor
is used, but it is installed correctly according to the instructions delivered with the
braking resistor.
The temperature of braking resistors increases significantly during operation. For this
reason, avoid coming into direct contact with braking resistors. Maintain sufficient
clearances around the braking resistor and ensure that there is adequate ventilation.
