Keysight AC6800B Series Operating and Service Guide 7
Safety and Regulatory Information
Shock Hazard
Before making any load or sense connections be sure to turn the POWER switch off and
remove the power plug from an outlet or turn off the circuit breaker of switchboard.
When the power switch is turned offwhile the output is on, residual voltage still remains
at the output terminals.
Do not touch the output terminal block for at least 20 seconds after the power switch is
tuned off.
When installing the switch between the OUTPUT terminal block and the load, be sure to
turn the POWER switch offand remove the power plug from an outlet or turn off the circuit
breaker ofthe switchboard.
Be sure to turn the switch off before connecting the load to the terminal at the load end of
the switch.
Do not touch the switch terminal or the output terminal when the output is on.
Do not remove the instrument covers. There are no customer-serviceable parts inside.
Some circuits are active and have power briefly after the power switch is turned off.
To prevent electric shock, unplug the unit before cleaning.
For protection from electrical shock, the power cordground must not be defeated. If only
a two-contact electrical outlet is available, connect the instrument’s chassis ground
screw (see above) to a good earth ground.
This product is an IEC Safety Class I equipment (equipment with a protective conductor
terminal). Be sure to ground (earth) the unit.
Connect the protective conductor terminal to earth ground.
In DC mode, L is at positive potential and Nis at negative potential when setting the
positive value. The opposite is true when setting the negative value.
Do not use the terminal block with the terminal cover removed.
Turn off the switchboard circuit breaker before connectingthe cord.
This product includes protective earth terminals. To minimize shock hazard, the
instrument must be connected to the AC power mains through a grounded power cable,
with the ground wire firmly connected to an electrical ground (safety ground)at the power
outlet. Any interruption of the protective (grounding)conductor or disconnection of the
protective earth terminal will cause a potential shock hazard that could result in personal
injury.
If a capacitor, battery, or similar device is connected as a load in DC mode, voltage
remains at the section connected to the output terminal block even when the output is off
until the load energy is discharged. The discharge time of the internal capacitor when no
load is connected is approximately 0.1 seconds. To prevent the possibility of electric
shock, do not touch the output terminal block.

Connecting the Power Cord
The power cord used with the product varies depending on the model. This product complies with IEC
Overvoltage Category II (energy-consuming equipment supplied from a fixed installation).
The AC6801B line cordhas a molded plug on both ends.
The AC6802B is a single-phase, cord-connected device that requires a plug
and cord set.
The AC6802B line cordmust have a plug on the utility side; you cannot hard
wire the instrument to the utility.
Possible Electric Shock
This product is an IEC Safety Class I equipment (equipment with a protective
conductor terminal). Be sure to ground(earth) the unit.
Connect the protective conductor terminal to earth ground.
AC6801B
Connect the power cord to the AC connector on the back of the instrument. Then connect the other
end to a properly grounded power outlet. You will use this plug to disconnect from mains power.
Use the supplied power cordto connect to the AC line. If the supplied power cordcannot be used due
to the rated voltage or the plug shape, have a qualified engineer replace it with an appropriate power
cord of length 3 m or less. If obtaining a power cord is difficult, contact Keysight.
The power cord with a plug can be used to disconnect the instrument from the AC line in an
emergency. Connect the plug to an easily accessible power outlet so that the plug can be removed
from the outlet at any time. Be sure to allow enough space around the power outlet.
To connect the power cord:
1. Check that the AC power supply meets the instrument's nominal input rating, which is any nominal
voltage from 100 to 120 VAC or 200 to 240 VAC. The frequency is 50 or 60 Hz.
Large voltage distortion on the AC power line can lead to malfunction. Do not
connect the instrument to a generator or a similar device.
2. Check that the power switch is turned off.
3. Connect the power cordto the AC input receptacle on the rear panel.
4. Insert the power plug into an outlet.

AC6802B, AC6803B, and AC6804B
The AC6802B requires use of a flexible plug and cord set which must be supplied by the user. The line
cord must have a plug on the utility side; you cannot hard-wire the instrument to utility mains.
The AC6803B and AC6804B instruments may be connected either by a flexible plug and cord set
supplied by the user or may, alternatively, be hard wired to the utility mains. See Switchboard and
circuit breaker requirements for guidance on branch circuit and circuit breaker sizing.
A switchboard circuit breaker disconnect must be provided when connecting
AC6803B and AC6804B models, regardless of whether the connection is
made with a flexible cord or by hard wiring the device to the AC utility.
Possible Electric Shock
Turn offthe switchboard circuit breaker before connecting the cord.
Do not use the terminal blockwith the terminal cover removed.
Possible Fire
Have a qualified engineer connect the power cord to the switchboard.
Make sure connections are correct
Protective circuits inside the instrument, including input fuses, are connected
to match the input terminal polarity. Make sure the colors of the wires connected to the input terminals (L,N, andGND) are correct.
1. Check that the AC power supply meets the instrument's nominal input rating, which is any nominal
voltage from 100 to 120 VAC or 200 to 240 VAC. The frequency is 50 or 60 Hz.
Large voltage distortion on the AC power line can lead to malfunction. Do
not connect the instrument to a generator or a similar device.
2. Check that the power switch is turned off.
3. On Model AC6802B, remove the terminal cover and cable clamp attached to the AC Input terminal
block.

4. Securely connect the power cord to match the L (line), N(neutral), and GND (ground)of the AC
Input terminal block. The protective earth terminal (ground)requires an extra length of wire compared
to the Line and Neutral wires. Always connect the ground wire first.
5. Install the terminal cover over the terminal block.
