Triple-Channel Power Supplies User's Manual Section 2:
2230G-900-01 Rev. A / June 2018 2-5
The voltage ranges of the two line voltage ratings are:
• 110 to 120 VAC: 99 VAC to 132 VAC (2230G-30-3) or 120 VAC:108 VAC to 132 VAC
(2230G-30-6 or 2230G-60-3)
• 220 to 240 VAC: 198 VAC to 264 VAC
The power cord supplied with the Series 2230G power supply contains a separate protective earth
(safety ground) wire for use with grounded outlets. When proper connections are made, the
instrument chassis is connected to ground through the ground wire.
In addition, there is a ground terminal for each channel on the rear panel. When a channel is
enabled, its ground terminal should be connected to a protective earth. In the event of a failure, not
using a properly grounded protective earth and grounded outlet may result in personal injury or death
due to electric shock.
Do not replace detachable mains supply cords with inadequately rated cords. Failure to use properly
rated cords may result in personal injury or death due to electric shock.
When using the model 2230G-30-6 or 2230G-60-3 in a country that is a member of the European
Union, you need to use the 2230G-HRM inductor box in line with the mains power cord to comply
with European Union regulations. If you use the inductor, the functions of the instrument are not
affected.
