(1). Overload Protection :
Usually the maximum current for the Energy Limiting Meter is 10A only.
When the current reach 20A, the meter will turn off in 30 seconds;
When the current reach 30A, the meter will turn off in 15 seconds;
When the current reach 40A, the meter will turn off in 5 seconds.
If the meter overload, LED is blinking "P_OV".
The Energy Limiting Meter will restore after 30 seconds for over-load off. If over-load is still there, it
will perform the over-load protection process.
After 10 attempts, it will stop the restore operation.
At this time, the users have to restore it manually.
