Table 6 shows the dielectric withstand voltage and the insulation resistance of the ACBs.
CAUTION
Do not perform dielectric withstand/insulation
resistance tests under other conditions than
specified. Doing so may cause a malfunction.
Table 6 Dielectric withstand voltage and insulation resistance
The above data applies to new ACBs. Device terminals within ACBs are not covered. Use a DC500V Megger to measure
the insulation resistance.
Table 7 shows the internal resistance and power consumption of the ACBs.
