3.2 Installing the braking resistor

3.2 Installing the braking resistor
The braking resistor should not be installed in the vicinity of the converter. The following
points must be taken into account:
● The braking resistors are only suitable for floor mounting.
● The maximum cable length between the Braking Module and braking resistor is 100 m.
● Sufficient space must be available for dissipating the energy converted by the braking
resistor.
● A sufficient distance from flammable objects must be maintained.
● The braking resistor must be installed as a free-standing unit.
● Objects must not be placed on or anywhere above the braking resistor.
● The braking resistor should not be installed underneath fire detection systems, since
these could be triggered by the resulting heat.
● For outdoor installation, a hood must be provided to protect the braking resistor from
precipitation (in accordance with degree of protection IP20).
