Check that the tester operates normally before starting the test.2Check the target location by sight and by reading out.3Insulate and cure the necessary parts of the cable side power connector, DC power distribution board and DC breaker to prevent short-circuit accidents.4No voltage check of the breaker Check that the target breaker on the power distribution board side is turned OFF by sight, and perform no voltage check on the power distribution board side using the tester.1Check that the red lead bar is connected to the + on the tester, and black lead bar to the –COM on the tester.2Change the tester range to VDC range. For a tester with the Ampere range, check with two people or more that the measurement is not performed in Ampere range and that the test bar insertion positions to the tester are correct.3Connect the red lead bar of the tester to the plus (+) pole of the target power distribution board breaker, and the black lead bar to its minus (-) pole.4Check that the value displayed on the tester is 0V (no voltage, logical value).5Disconnect both the lead bars of the tester from the breaker terminals.5Cable Side Power Connecter Voltage CheckCheck that the target power distribution side breaker is turned OFF by sight, and perform no voltage check of the cable side power connecter using the tester.1Connect the red lead bar of the tester to the 0V terminal (pin 2) on the cable side power connector, and the black lead bar to its -48V terminal (pin 1).2Check that the value displayed on the tester is 0V (no voltage, logical value).
76Voltage Check6Keep each lead bar (red and black) of the tester connected as is, and instruct another worker to turn ON the target breaker.GAfter the worker checks the position of the target breaker by the drawing, the target device name displayed on the power distribution and the destination plate attached to the power cable, the worker turns ON the target breaker. Moreover, the supervisor would always be present and checks on the work.7Check that the breaker switch is turned ON, and 48V (logical value) is displayed on the tester.8Keeping the red lead bar connected to the 0V terminal (pin 2) of the cable side power connector, slowly move the black lead bar to the grounding terminal (E or FG) and connect to it. Upon connection, check that the voltage changes from 48V to 0V (logical value).
77Voltage Check9Keep the black lead bar connected to the grounding terminal (E or FG), slowly move the red lead bar from the 0V terminal (pin 2) of the cable side connector to the -48V terminal (pin 1), and connect to it. Upon connection, check that the voltage changes from 0V to -48V.10 Check that the polarities of the logical value and the actual measurement value are the same, the voltage value is almost the same as the above logical value, in a range allowed by the device characteristics, or is an appropriate voltage specified by the rectifier.11 When the voltage check is complete, check the target breaker again and turn the breaker OFF (upon turning OFF, check again that the cable side power connector is in 0V (no voltage)).12 Remove the cure materials, and attach the power distribution board breaker terminal protection cover (fix by screws and check the tightening).13 Connect the cable side power connecter to the power connector on the equipment side.14 Clean up the site.
