NOTE:
y The external braking resistor is only allowed to be installed with a supply
unit that does not have an internal braking resistor.
y Be sure to follow the installation instructions for the external braking
resistor.
y The minimum permissible connection resistance for the supply unit must
not be infringed. For technical data on the design of the braking resistors,
see Appendix Table A.2, p.75, Table A.5, p.76 and Table A.8,
p.78.
y The cable cross-section is dependent on the braking resistor's power
rating, see Table A.3, Table A.6 and Table A.9
y The cables are to be protection by suitable means.
4.16 Overview of the step-up choke
connections
In the following you will nd the layout with the corresponding positions and labels on the
terminals. The temperature is evaluated using a KTY sensor via terminal X5. At 145°C
the supply unit is shut down. For technical data on the step-up choke, see chap.A.7,
p.82.
