10.2.1 To prevent electrical hazards
When performing service to inverter equipment:
1 Do NOT open the electrical component box cover for 10minutes after turning
off the power supply.
2 Measure the voltage between terminals on the terminal block for power
supply with a tester and confirm that the power supply is shut off. In addition,
measure points as shown in the figure, with a tester and confirm that the
voltage of the capacitor in the main circuit is less than 50VDC. If the voltage
measured is still higher than 50 V DC, discharge the capacitors in a safe
manner by using a dedicated capacitor discharge pen to avoid possibility of
sparking.
