Application The MultiSafe DSP-UB 3 is a two-pole voltage tester to test on railway lines with lateral power supply (3rd-rail). Thanks to its green and red LEDs, the display is easy to see even in dark surroundings. The firmly attached magnet and the extension allowing greater safety distances and ease of handling.
- Page 4 Workings may only be performed with appropriate personal protective equipment. Observe the minimum object distance to other plant components that are energized or earthed and use personal protective equipment as speci- fied by national accident prevention regulations (in Germany: DGUV V3 or DIN EN 50110-1). The function of the voltage tester must be checked briefly before and whenever possible after the use.
- Page 5 3.2 Establish contact with the earth Place the contact magnet on the bare rail. The contact surface must be clean and free from coarse rust. 3.3 Checking the function with the integrated self-test Step 1 – Test of the display The device must be switched off for the self-test.
- Page 6 4. Measuring and testing Attention! The function test (see 3.3) has to be performed successfully. The voltage tester does not switch on automatically when voltage is applied. After a successful self-test, contact the power rail with the O-electrode of the extension. The O-electrode must be rotated so that the busbar is touched as shown below.
