15.2.9.1 Variable Resistors (VR), Light-Emitting Diodes, and Check Pins by PCB
0019-0574
iR3225 / iR3225N / iR3235 / iR3235N / iR3245 / iR3245N
Of the variable resistors (VR), light-emitting diodes (LED), and check pins found in the machine, those that are needed when servicing the machine in the field are
discussed.
15.2.9.2 Points to Note About the Leakage Breaker
0019-0576
iR3225 / iR3225N / iR3235 / iR3235N / iR3245 / iR3245N
- Some LEDs carry current and emit light when they are off; this is a normal condition, and must be kept in mind.
- Take note of the following:
: VR that may be used in the field.
: VR that must not be used in the field.
Points to Note When Checking the Output of a PCB
Normally, an AC voltage is applied to the terminal of the leakage breaker [1].
Take care not to touch it when making a check.
