3.4 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).
WARNING
Fire as a result of inadequate installation
If incorrectly installed (non-observance of the cooling clearances or inadequate clearances
to flammable objects), there is the danger of fire damage with death or severe injury.
•
It is essential that you maintain a cooling clearance of 200 mm on all sides of the
braking resistor with ventilation grills.
•
Maintain sufficient clearance to objects that can burn.
CAUTION
Burns due to a high surface temperature at the braking resistor
In operation, the braking resistor can reach high temperatures, which can cause burns if
touched.
•
Allow the braking resistor to cool down before starting any work.
• Use the appropriate personnel protection equipment, e.g. gloves.
