5.1 Mains input (X2)
The mains input is prepared for direct mains 230 VAC or 230 VAC to 480 VAC input
voltage, depending on the selected power supply module. If the neutral point of the
connected mains is not grounded, an over voltage protection unit has to be installed in the
input of the switchgear cabinet ( page 35).
Note: If the DC-link of two or more MDD 100 systems are linked with the
same supply voltage, the mains inputs must also be linked.
