be ruled out.
CAUTION
Risk of burns resulting from high surface temperature of the braking resistor
The braking resistor can become very hot. You can be severely burnt when touching the
surface.

Mount the braking resistor so that it cannot be touched. If this is not possible, at the dangerous
locations, attach an appropriate warning note that is clearly visible and easy to understand.
WARNING
Fire hazard due to heat dissipation from a braking resistor
An incorrectly installed braking resistor can cause overheating of components with resulting
fire and smoke.

Only mount braking resistors on the floor.

Mount the braking resistors so that they are in the vertical position and freestanding. Sufficient
space must be available for dissipating the energy converted by the braking resistor.

Maintain sufficient clearance to objects that can burn.

Do not place any objects on or above the braking resistor.
NOTICE
Damage to braking resistor due to ingress of water
The ingress of water can damage the braking resistor.

To maintain degree of protection IP20, provide a canopy to protect against rain when mounting
outside.
