Voltage Check
9
Keep 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.
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.

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.

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)).
