ULTRA-CUT 400
Check / Adjust Input Voltage Configuration for 208/230 and 460V Systems
1. The 208/230 and 460 V power supply includes a voltage configuration board which must be positioned to match
the primary input voltage. Remove the power supply left and right side panel and locate the voltage configura-
tion board. The input voltage configuration is shown at the top of the board for three on the left side and on the
bottom for the single one on the right side. See NOTE.
2. If necessary, disconnect the jumper at the top right corner of the board, remove the board and re-install it with
the correct input voltage shown at the top of the board.
3. Re-connect the jumper. Re-install the power supply side panel.
NOTE:
There are 4 inverters in the power supply. 3 on one side and 1* on the other. The single inverter will be installed
opposite of the other 3 so the 460V will be on the bottom when the other 3 will be on top as shown below.
1. Unplug connector
2. Remove bolts.
3. Invert board.
4. Re-install board.
5. Plug in connector.
