How to Measure Insulation Resistance
A multimeter is required to measure insulation resistance. When checking, turn off the power and
disconnect the power cable completely from the power socket. Make a report after measurement
to check the variation in resistance value at each inspection.
Measuring Insulation Resistance in AC Input Stage
Measure the AC input terminal with the multimeter as follows.
The normal range is as follows.
Inspection item Connection terminal Normal value
AC power input
AC220.L – AC220.N 50 kΩ or larger
AC220.L – F.G. 1 M Ω or larger
AC220.N – F.G. 1 M Ω or larger
Measuring Insulation Resistance in DC Output Stage
Measure the DC output terminal with a multimeter as follows.
The normal range is as follows.
Inspection item Connection terminal Normal value
DC power output
DC48V - GND 1 0 kΩ or larger
DC24V - GND 70 0 Ω or larger
