Overview Of The Step-Up Choke Connections - Keba ServoOne Series Operation Manual

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 find 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.
DANGeR! Risk of injury due to electrical power!
• Carelessness will result in serious injuries or death.
The choke is only intended for installation in a switch cabinet, as with IP00 protection it offers
no protection against direct or indirect touching.
WARNING! Risk of injury due to hot surfaces on the choke!
• Carelessness may result in serious burns.
The choke may reach a temperature of up to 145 °C during operation!
Only touch the choke with gloves or after a longer cooling phase.
