TRT30C Introduction M-T030CN-203-EN 3 1 Introduction The purpose of this Manual is to provide helpful instructions on how to use the TRT30C instrument safely, properly and efficiently. The following instructions will help the user avoid unsafe situations, reduce maintenance costs and will ensure the reliability and durability of the TRT30C instrument. The TRT30C must be used in accordance with all existing safety requirements and regulations based on national/local standards for accident prevention and environmental protection. In addition, the relevant international standards are listed in paragraph 5.6 of the “Technical Data” section of this document. 1.1 Safety Instructions Safety is the responsibility of the user. Before operating the TRT30C, please read the following safety instructions carefully. It is not recommended that the TRT30C is used (or even turned on) without careful observation of the instructions listed in this Manual. The TRT30C should only be operated by trained and authorized personnel. 1.1.1 Safety Terms and Symbols Terms in this Manual These terms may appear in the Manual: WARNING: Warning statements identify conditions or practices that could result in injury or loss of life. CAUTION: Caution statements identify conditions or practices that could result in damage to this product or to other property. Terms on the Device The following warning terms used in this document may appear on the device: WARNING: Warning indicates that potential hazard may occur. CAUTION: Caution indicates that potential damage may occur to the instrument or to the test object connected to the instrument. Symbols on the Device The following symbols may appear on the device: Refer to Protective Manual Earth Terminal 1.1.2 Terms of Use • The TRT30C shall be used only if it is in good technical condition. Its use shall be in accordance with local safety and industrial regulations. Adequate precautions must be taken to avoid any risks related to high voltages associated with this equipment and nearby objects. • The TRT30C shall be used only for the application purposes described in the ”Intended Use” section. The manufacturer and distributors are not liable for damage resulting from wrong usage. The user bears responsibility for not following the instructions defined in this document. TRT30C Introduction M-T030CN-203-EN 4 • Do not remove the protective casing of the TRT30C. • All service and maintenance work must be performed by qualified personnel only. 1.1.3 Orderly Practices and Procedures • The Manual shall always be available on the site where the TRT30C is used. • Before using the TRT30C, all personnel (even personnel who only occasionally, or less frequently, work with the TRT30C) assigned to operate the TRT30C should read the operations Manual. • Do not make any modifications, extensions, or adaptations to the TRT30C. • Use the TRT30C only with the original accessories provided by the manufacturer. • Use the TRT30C and its original accessories for the device’s intended use only. 1.1.4 Instrument Maintenance The device should be kept clean in order to prevent excessive cases of dust or other contaminants affecting its operation. It should be cleaned with water/isopropyl alcohol after any dirt/contaminants are noticed on its surfaces. 1.1.5 Operator Qualifications • Testing with the TRT30C should only be carried out by authorized and qualified personnel. • Personnel receiving training, instruction or education on the TRT30C should remain under the constant supervision of an experienced operator while working with the test set and the test object. 1.1.6 Safe Operating Procedures • Hazardous voltages of up to 400 V can occur inside the TRT30C. Therefore, it is not permitted to remove the protective casing of the TRT30C. • Hazardous voltages exist on the terminals of the TRT30C when the “Red” LED is lit. Never assume that the connections are safe even if this LED is off. Switch off and unplug the TRT30C before touching the connections, particularly if a fault is suspected. • Before putting the TRT30C into operation, check the test set for any visible damage. • Do not operate the TRT30C under wet or moist conditions (condensation). • Do not operate the TRT30C if explosive gas or vapors are present. • Only the external devices which meet the requirements for SELV equipment according to EN 60950 or IEC 60950 should be connected to the TRT30C through the serial interface. • Removing theTRT30C protective casing will void the warranty. Any work inside the instrument without prior authorization from DV Power will also void the warranty. • If the TRT30C seems to be malfunctioning, please contact the DV Power Support Team (refer to the “Manufacturer Contact Information” section) after previously checking the “Error Messages” section. • Prior to connecting the TRT30C, ensure that the transformer (object) to be tested is completely de- energized and isolated from both the line and the load. Every terminal should be checked and verified before connecting the TRT30C. Ground connections may be left in place. • Do not use the TRT30C without the extra protective ground cables supplied with the TRT30C. It must never be operated in a non-grounded configuration as this may result in an electrical shock to the user or damage to the TRT30C. Always establish this connection first before establishing any other connections and remove this connection as the very last one.
