III. OTHER SPECIFIED TESTING The following is a general description of certain tests that are performed on representative SUNON fans. Nothing in this document is intended to suggest that these tests are performed on every model of SUNON fan. Moreover, the descriptions that follow each test are meant only to provide a general explanation of each test. If you would like a more detailed explanation as to any test identified in this Section, SUNON can provide such an explanation upon request. 1.
IV. CHARACTERISTIC DEFINITION The following is a general description of certain tests that are performed on representative SUNON fans in order to determine the specifications of the fan. Nothing in this document is intended to suggest that these tests are performed on every model of SUNON fan. Moreover, the descriptions that follow each test are meant only to provide a general explanation of each test.
4. RATED SPEED Measured after continuous 10 minute operation at rated voltage in clean air ( STATIC PRESSURE=0), and at ambient temperature of 25 degrees C under shaft horizontal condition. 5. STARTING VOLTAGE Measured the voltage which enables to start the fan in the clean air (static pressure = 0 ) by switching on at the voltage under shaft horizontal condition. It is not at continuously increasing voltage adjustment. 6. LOCKED ROTOR CURRENT Measured immediately after the fan blade is locked. 7.
D.C.C. 2018.02.26 V. NOTE Ⅰ.SAFETY 1. DO NOT use or operate this fan in excess of the limitations set forth in this specification. SUNON is not responsible for the non-performance of this fan and/or any damages resulting from its use, if it is not used or operated in accordance with the specifications. 2. SUNON recommends adding a protection circuit to the product or application in which this fan is installed, such as a thermo-fuse, or current-fuse or thermo-protector.
II. SPECIFICATION MODIFICATION 1. SUNON offers engineering assistance on fan installation and cooling system design. 2. All changes, modifications and/or revisions to the specifications, if any, are incorporated in the attached specifications. 3. No changes, modifications and/or revisions to these specifications are effective absent agreement, by both SUNON and the customer, in writing. 4.
5. This fan must be installed properly and securely. Improper mounting may cause harsh resonance, vibration, and noise. 6. Fan guards may prevent injury during handling or installation of the fan and are available for sale with this fan. 7. Unless otherwise noted, all testing of this fan is conducted at 25°C ambient temperature and sixty-five percent (65%) relative humidity. 8. DO NOT store this fan in an environment with high humidity.
