The "UPS output" and "Mains input" plug connections are on potential
mains when in the connected state.
Even in an unconnected state, dangerously high voltage on the plug con-
nections can result from the capacities charged within the device.
As soon as the mains input voltage is present, the charging unit is automati-
cally active. Meaning, the internal battery bank is already being charged with-
out the UPS being started.
