e.Replace the cover and mark the supply clearly with a tag or label indicating the correct line voltage and fuse that is in use.

Power Cord
To protect operating personnel, the instrument should be grounded. This instrument is equipped with a three conductor power cord. The third conductor is the ground conductor and when the power cord is plugged into an appropriate receptacle, the supply is grounded.
The power supply was shipped with a power cord for the type of outlet used at your location. If the appropriate cord was not included, contact your nearest Agilent Sales Office to obtain the correct cord.
OPERATING INSTRUCTIONS
INTRODUCTION
This section explains the operating controls and indicators and provides information on many operating modes possible with your instrument. The front panel controls and indicators are illustrated in Figure 3.
Figure 3. Front-Panel Controls and Indicators
1.LINE Switch: Pressing this switch turns the supply on, or off.
2.VOLTAGE Control: Clockwise rotation increases output volt- age.
3.CURRENT Control: Clockwise rotation increases output cur- rent.
4.DISPLAY OVP/CC SET Switch: Pressing this switch causes the VOLTS display to show voltage setting for overvoltage shutdown (trip voltage) and the AMPS display to show the current control set value. Setting values are either front panel settings or remote voltage programmed settings.
5.OVP Adjust Screwdriver Control: While pressing the DIS- PLAY OVP/CC SET switch, rotating the control
6.VOLTS Display: Digital display of actual output voltage, or OVP shutdown setting.
7.AMPS Display: Digital display of actual output current, or
8.CV LED Indicator: Output voltage is regulated when lighted. This means the power supply is operating in the constant volt- age mode.
9.CC LED Indicator: Output current is regulated when lighted. This means the power supply is operating in the constant cur-
rent mode.
10.OVP LED Indicator: Output is shutdown by the occurrence of an overvoltage when lighted. Removing the cause of over- voltage and turning the power off, then on, resets the power supply.
TURN-ON CHECKOUT PROCEDURE
The following checkout procedure describes the use of the front panel controls and indicators illustrated in Figure 3 and ensures that the supply is operational:

a.Disconnect power cord.
b.Check that the
c.Check that the rear panel label indicates that the supply is set to match your input line voltage (If not, refer to "Line Voltage Option Conversion".).
d.Check that the fuse on the rear panel is correct for your line voltage.
e.Connect the power cord and push the LINE switch to ON.
f.While pressing OVP/CC SET switch, verify that the OVP shutdown is set above 8.0, 20.0, 35.0, or 60.0 Vdc for E3614A, E3615A, E3616A, or E3617A respectively. If not, turn up OVP Adjust with a small
g.Turn VOLTAGE control fully counter clockwise to ensure that the output of VOLTS display decreases to 0 Vdc, then fully clockwise to ensure that output voltage increases to the maxi- mum output voltage.
