8.1.2 Regular Maintenance
The power supply must be cut off before regular maintenance. Only after the monitor has
no display and charge LED has lit off 5-10 minutes can the maintenance begin. On the
other hand, you will risk electric shock because there are storage capacitors within the
inverter that will hold charge even after the input power is disconnected.
The regular maintenance contents and cautions are listed in Table 8-2.
