KTR-N 49015 EN Torque Measuring Shaft Sheet: 5 of 21 Operating/Assembly instructions Edition: 5 2 Advice 2.1 General advice Please read through these operating/assembly instructions carefully before you start up the measuring shaft. Please pay special attention to the safety instructions! The operating/assembly instructions are part of your product. Please store them carefully and close to the measuring shaft. The copyright for these operating/assembly instructions remains with KTR. 2.2 Safety and advice symbols This symbol indicates notes which may contribute to Warning of potentially explosive preventing bodily injuries or serious bodily injuries that atmospheres may result in death caused by explosion. This symbol indicates notes which may contribute to STOP Warning of personal injury preventing bodily injuries or serious bodily injuries that may result in death. This symbol indicates notes which may contribute to ! Warning of product damages preventing material or machine damage. This symbol indicates notes which may contribute to General advice preventing adverse results or conditions. 2.3 General hazard warnings With assembly, operation and maintenance of the measuring shaft 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 indications. All operations on and with the measuring shaft 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 measuring shaft. 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 measuring shaft as long as it is in operation. Secure the rotating components of the measuring shaft against accidental contact. Please provide for the necessary protection devices and covers. Please observe protection Drawn: 2017-01-02 Pz Replacing: KTR-N dated 2016-07-20 note ISO 16016.

KTR-N 49015 EN Torque Measuring Shaft Sheet: 6 of 21 Operating/Assembly instructions Edition: 5 2 Advice 2.4 Intended use You may only assemble, operate and maintain the measuring shaft if you have carefully read through the operating/assembly instructions and understood them had technical training are authorized by your company The measuring shaft may only be used in accordance with the technical data (see chapter 1). Unauthorized modifications on the measuring shaft 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. The DATAFLEX® torque measuring shaft described in here corresponds to the technical status at the time of printing of these operating/assembly instructions. 3 Storage, transport and packaging ! 3.1 Storage The RADEX®-N couplings are supplied in preserved condition. Both DATAFLEX® and RADEX®-N can be stored at a dry and covered place for 6 - 9 months. Humid storage rooms are not suitable. Please make sure that condensation is not generated. The best relative air humidity is less than 65 %. 3.2 Transport and packaging In order to avoid any injuries and any kind of damage please always make use of proper transport and lifting equipment. The couplings are packed differently each depending on size, number and kind of transport. Unless otherwise contractually agreed, packaging will follow the in-house packaging specifications of KTR.
