example, as the following graphics shows: the WATT of the load is 9KW, VA is 10KVA (when disconnect load,
it is a normal phenomenon to show a small numerical value of WATT and VA).
Temperature: Display the maximum temperature of the components in the UPS. As the following graphics
shows: the maximum temperature is 40℃.
