4.8.1 Permitted installation of braking resistors
The surfaces of the resistors get very hot if loaded with nominal power. Make sure that
you select an installation site that will accommodate these high temperatures. Braking
resistors are therefore usually mounted on the control cabinet roof.
NOTICE
Braking resistors can overheat.
Non-permissible installation might lead to an accumulation of heat in the braking res-
istor due to reduced convection. A tripping temperature contact or an overheated
braking resistor can lead to a system standstill.
ü Adhere to the following minimum clearances:
• About 200mm to adjacent components and walls.
• About 300mm to above components/ceilings.
Observe the following permitted mounting positions when installing the resistors:
• Grid resistor
