SAFETY INSTRUCTIONS
Power cord for the United Kingdom
When using the instrument in the United Kingdom, make sure the
power cord meets the following safety instructions.
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the
following code:
Green/ Yellow: Earth
Blue: Neutral
Brown: Live (Phase)
As the colours of the wires in main leads may not correspond with
the coloured marking identified in your plug/appliance, proceed
as follows:
The wire which is coloured Green & Yellow must be connected to
the Earth terminal marked with either the letter E, the earth symbol
or coloured Green/Green & Yellow.
The wire which is coloured Blue must be connected to the terminal
which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the
terminal marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment
or contact the supplier.
This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse: refer to the rating information on the
equipment and/or user instructions for details. As a guide, a cable
of 0.75mm
conductors would normally require 13A types, depending on the
connection method used.
Any exposed wiring from a cable, plug or connection that is
engaged in a live socket is extremely hazardous. If a cable or plug is
deemed hazardous, turn off the mains power and remove the cable,
any fuses and fuse assemblies. All hazardous wiring must be
immediately destroyed and replaced in accordance to the above
standard.

First Time Use Instructions
Use the procedures below when first using the PEL-3000E to install
the rack mount kit, power up the instrument, restore the factory
default settings and check the firmware version. Lastly, the
Conventions section will introduce you to the basic operating
conventions used throughout the user manual.
Power Up and Self Test
Steps
Note
1. Insert the AC power cord into the power
socket.
2. Turn the external
power switch on.

3. If the unit doesn’t turn on, press the
On/Standby key.
The ON/STBY key will go from standby (red)
to on (green).
4. The unit will show the splash screen and then
load the settings from when the unit was last
powered down.
If the PEL-3000E fails to start up properly or does
not turn on, please see you local distributor.

Wire Gauge
considerations
Before connecting the unit to a power source,
the wire gauge must be taken into account.
Load wires must be large enough to resist
overheating when a short-circuit condition
occurs as well as to maintain a good
regulation. The size, polarity and length of a
wire are all factors in determining if a wire
will withstand short circuiting.

Wires that are selected must be large enough

When using the PEL-3000E load generator,
voltage drop and voltage generated due to
load line inductance and current change must
be taken into account. Extreme changes in
voltage may exceed the minimum or
maximum voltage limits. Exceeding the
maximum voltage limit may damage the PEL3000E.
To determine the voltage generated, the
following equation can be used.
E = L x (∆ I / ∆ T)
E= voltage generated
L=load line inductance
∆ I= change of current (A)
∆ T= time (us)
Load line inductance (L) can be approximated
as 1uH per 1 meter of wire. (∆ I / ∆ T) is the
22
GETTING STARTED
slew rate in A/us.
Limiting Load line
inductance
The diagram above shows how changes in current
can affect voltage.
Load line inductance can be reduced in two
ways.
1. Ensure load wires are as short as possible
and twist the positive and negative load wires
together.
2. Current change can be limited by limiting
the slew rate speed when switching in CR and
CC mode.
“Twisted pair” will be shown on any
connection diagram where the load wires
should be twisted together.

Connection
Caution
The PEL-3000E has input terminals on the
front panel.
Follow the procedures below for the load
connection. Please adhere to the following
precautions to ensure your safety and to
protect the unit from damage.
When connecting the PEL-3000E to the DUT,
make sure that the polarity of the connection
between the DUT and the unit matches.
Ensure that the maximum input voltage is not
exceeded. The maximum input voltage is 150
volts (PEL-3031E).
If the polarity to the input terminals is reversed,
the reverse voltage protection function is tripped.
The reverse voltage protection function is tripped

1. Turn the power off from the rear panel or put
the unit into standby mode.
2. Turn the power off from the DUT.
3. Connect the load wires to the input terminals:
Connect the positive (+) input terminal on the

Remote Sense
PEL-3000E Series User Manual
Description
Steps
Remote sense can be used to help compensate
for long cable length. The longer the cable, the
higher the potential resistance and inductance,
therefore a short cable is best. Twisting the
cable can help reduce induced inductance and
using the Vsense terminals compensates the
voltage drop seen across the load leads,
especially leads with higher resistance. This is
useful when used in CV, CR or CP mode.
1. Turn the power off from the rear panel or put
the unit into standby mode.
2. Turn the power off from the DUT.
3. Connect the DUT to the load terminals, see
page 21, 24.
4. Connect the sense wires to the sense terminals:
Connect the positive sense (+S) terminal to the
high potential output of the DUT.
Connect the negative sense (-S) terminal to the
low potential output of the DUT.

Warning
Firmware Update
Description
System version
Operation
1. Press
Ensure that the load is connected to the DUT
before connecting the sense wires. If only the
sense wires are connected to the DUT, the load
will be seen at the sense terminals. This will result
in an internal fuse entering a high-impedance
state due to over temperature. At this point, any
measured values will be erroneous. You must wait
for the temperature to return to normal operating
temperature before the unit should be used again.
The PEL-3000E allows the firmware to be
updated by end-users. Before using the PEL3000E, please check the GW Instek website or
ask your local distributor for the latest
firmware.
Before updating the firmware, please check
