When no external voltage is present; the ISMG3 inverter can still contain high
voltages. There is still risk of electrical shocks.
Allow at least 5 minutes for the inverter to discharge completely after
disconnecting the AC and DC sources from the inverter.
External heat sinks can reach a relatively high temperature in normal
operation and cause skin burn injury if touched. Pay attention to it.
To prevent the risk of fire hazard, do not cover or obstruct the heat sink.
