Braking resistors for Braking Modules

7.1.7.1

Installation of the braking resistors

Ideally, external braking resistors should be installed outside of the control cabinet to prevent
the heat lost by the resistors from subjecting the cabinet to thermal stress.
The resistor may be installed inside the control cabinet either standing on the cabinet floor or
suspended (horizontally or vertically) from the cabinet wall. You must ensure that the braking
resistors do not obstruct the flow of cooling air to the drive line-up.
The braking resistor can become very hot. Consequently, it must be installed so that it
cannot be touched or, if this is not possible, an appropriate warning notice must be
attached to it.
