d.Operation instructions
Standard intelligent controller setting
According to the panel number 9 showed, dial the switch 11,14,20 to set the time you need.
According to the panel number 10 showed, dial the switch 12,15,17,19 to set the current you need.
Example 1: means that overload long time-delay current is 0.9In, overload long time-delay time is 60s.
Example 2: means that short circuit short time-delay current is 4In, short circuit short time-delay time is 0.4s.
