AC Power Considerations

The UP4000 Series draw an average AC line current as indicated on the following chart:

	115VAC	230VAC
UP4060	1.5A	0.8A
UP4120	4.0A	2.0A
UP4160	4.8A	2.4A

Voltage Conversion

The UP4000 Series can be configured to operate at 115 VAC or 230 VAC. Be sure the VOLTAGE SELECTOR switch on the rear panel is set to the correct position for the AC power supply being used.
