E36xxA: Setting the Line Voltage
Question: How do I change the power-line voltage setting for an E36xxA Series power supply?
Answer: Certain model families have different methods for changing the line voltage as listed below. Always make
sure that the correct fuse is installed before powering up after changing the line voltage. For more information, see
"Line Voltage conversion" in the manual. Also check the manual for the correct fuse values. Before attempting to
change the line voltage value, always make sure that the unit is unplugged first.
For the E3610A, E3611A, and E3612A:
It is not possible to change the line voltage setting on these supplies.
For the E3614A, E3615A, E3616A, E3617A, E3620A, and E3630A:
The power line voltage selection switch is located on the inside of the unit. First open the top cover of the power
supply. Then change the voltage setting using the selection switch located on the PC board.
For the E3631A and E3632A:
The power line voltage selector is located on the rear panel of the instrument. Remove the power line module from
the rear panel (located near the ac receptacle). Rotate the power line voltage selector until the correct voltage
appears. Replace the power line module in the rear panel.
For the E364x:
The line selection switch located inside the unit allows the line voltage to be changed. To change the line voltage,
open the top cover of the instrument and configure the selection switch located on the PC board.
