Guidelines for Installation
The connecting cables to the Braking Module in the Basic Line Module, Smart Line Module,
Active Line Module, or Motor Module must be kept as short as possible (maximum of 100 m).
The braking resistors are only suitable for floor mounting.
The maximum cable length between the cabinet unit 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 ensured.
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 should be provided to protect the braking resistor against
precipitation (in accordance with degree of protection IP20).
Connecting the braking resistor
Hazardous electrical voltage
The Braking Module must only be connected when the Basic Line Module, Smart Line
Module, Active Line Module, or Motor Module has been disconnected from the power
supply and the DC link has been discharged.
Risk of fire and damage to equipment due to short-circuit/ground fault
The cables to the braking resistor must be routed so that a ground fault or short circuit can
be ruled out. A ground fault can result in fire with the associated smoke.
Protect the cables from mechanical damage.
Comply with local installation regulations that enable this fault to be ruled out.
In addition, apply one of the following measures:
Use cables with double insulation.
Maintain adequate clearance, using spacers, for example.
Route the cables in separate cable ducts or pipes.
