MC032 - MCP-25 Control
The main power supply must be either 115/230VAC, 50/60 Hz, 6.3A. The
155/230VAC power requirement is field-selectable. The power-entry module
accepts a standard IEC power cord, which is supplied.
To connect the main power supply to the MCP-25 control, follow these steps:

If the control will be connected to 115VAC, rotate the
drawer so that 115V will show through the door
opening.
If the control will be connected to 230VAC,
rotate the drawer to the 230V position.
