4.4.1 RECOMMENDED WIRING PRACTICE
Be sure to connect MCCBs between the power supply and PA7300 input terminals L1 (R),
L2 (S), L3 (T). Recommended MCCBs are listed in Table 3.
When a ground fault interrupter is used, select one with no influence on high frequency. The
current setting should be 200mA or higher and operating time at 0.1 second or higher to
prevent malfunction.
