Voltage inputs - MID
Voltage connection Direct
Rated voltage L-N 230 V
Rated voltage L-L 400 V
Voltage tolerance From 0.8 to 1.15 Un
Overload Continuous: 1.5 Un max
Input impedance Refer to “Power supply”
Frequency 50 Hz
Voltage inputs - Non MID models
Voltage connection Direct
Rated voltage L-N (from Un min
to Un max)
120 to 240 V
Rated voltage L-L (from Un min
to Un max)
208 to 415 V
Voltage tolerance From 0.8 to 1.15 Un
Overload Continuous: 1.5 Un max
Input impedance Refer to “Power supply”
Frequency From 45 to 65 Hz
Note: for MID versions the voltage range is limited to 3x120 (208)...3x230 (400) V, frequency to 50Hz.
Note: EM530 can also be installed in a wild leg system (three phases, four delta wires), where one of the
phase-neutral voltages is higher than the other two.
