Connect the mains to the 48-300W Modular Switched Mode Rectifier System AC input according the shelf
configuration. Please observe the following recommendations:
• Pigtail (1.5m cable): first connect the yellow/green protective earth cable to the protective earth of the
mains before connecting the neutral and line.
• IEC: Insert a 3-pole IEC C15 plug only (see Figure 22)
• Dual IEC: Insert two 3-pole IEC C15 plugs (see Figure 22)
A complete mains cord kit can be purchased from Alpha Technologies.

EMC ground
If necessary for the end user system and for better EMC performance connect a ground cable to the common
ground of the shelf (M4 thread at the rear side). It is also possible to use this M4 thread to ground the positive
pole of the 54Vdc output. This ground is not a protective earth. Protective earth is provided by the 3-pole mains
cable.
