With assembly and disassembly of the damping rods it has to be made sure that the entire
drive train is secured against accidental switch-on. You may be seriously hurt by rotating
parts. Please make absolutely sure to read through and observe the following safety indica-
tions.
• All operations on and with the damping rods have to be performed taking into account "safety first".
• Please make sure to switch off the power pack before you perform your work on the damping rods.
• Secure the power pack against accidental switch-on, e. g. by providing warning signs at the place of switch-on
or removing the fuse for current supply.
• Do not reach into the operation area of the machine as long as it is in operation.
• Please secure the rotating drive components against accidental contact. Please provide for the necessary
protection devices and covers.
You may only assemble and disassemble the damping rods if you
• have carefully read through the operating/assembly instructions and understood them
• are technically qualified and specifically trained (e. g. safety, environment, logistics)
• are authorized by your company
The damping rod may only be used in accordance with the technical data (see chapter 1). Unauthorized modifica-
tions on the damping rods are not admissible. We will not assume liability for any damage that may arise. In the
interest of further development we reserve the right for technical modifications.

Frequently Answers and Questions
What is the purpose of KTR Damping rods?
KTR Damping rods are designed to reduce noise levels and dampen vibrations produced by machinery during operation.
What types of damping rods are available?
The manual describes 4 types of damping rods: DSM, DSFL, DSFS, and DSK. They are compatible with different components like electric motors, foot flanges, and oil coolers.
How do I install KTR Damping rods with an electric motor?
The damping rods are installed by fitting the electric motor's feet onto them. The screws used must be the appropriate length and tightened to the specified torque.
