5.4 Routine inspection and period inspection

To ensure stable and safe operations, check and maintain the inverter regularly and
periodically.
The table below lists the items to be check to ensure stable and safe operations.
Check these items 5 minutes after the "Charge" indicator goes out to prevent service
persons from being hurt by residual electric power.
