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:
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
0.75mm2 should be protected by a 3A or 5A fuse. Larger 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.

Setting up the Booster Pack
This section describes how to set up the booster pack
properly including turning the unit on, choosing the
correct wire gauge, and connection details.
The PEL-3211(H) has a STBY indicator on the front
panel to indicate when the power is on.
1. Insert the AC power cord into the power socket.
2. Turn the power switch on
from the rear panel.
(O → —)
3. The STBY indicator will turn red when the power is
on.
STBYLINK
LINK STBY
Before connecting the booster packs to a DUT, 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 to
withstand a short circuit and limit voltage drops to no
more than 2V per wire. Use the following table to help
make a suitable selection.

Load Line Inductance Considerations
When using the booster packs, 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 booster(s).
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 or response speed when switching in CR and
CC mode.
Using the Rear Panel Terminals
The rear panel input terminals accept up to M8-sized
crimped terminals. The rear terminals come with a
load input terminal cover for safety.
1. Turn the power off from the rear panel.
2. Turn the power off from the DUT.
3. Connect the load wires to the input terminals:
Connect the positive (+) input terminal on the
load generator to the high potential output of the
DUT.
Connect the negative (-) input terminal to the
low potential output of the DUT.

Using the Terminal Cover (PEL-011)
The rear panel terminal cover should be used to
prevent electric shock. The rear panel terminal covers
should always be used when connecting a load to the
rear panel terminals.
Warning
Ensure the power is off before making
any connections to the booster pack.
1. Remove the screw holding the top cover to the
bottom cover.

2. Line-up the bottom cover with the notches in the
output terminals.
3. Place the top terminal cover over the bottom cover.

4. Use your thumb to slide the terminal covers shut.
5. When the top and bottom covers are flush, reinsert
the screw that was removed in step 1.
Using the Terminal Cover (PEL-013)
The rear panel terminal cover should be used to
prevent electric shock. The rear panel terminal covers
should always be used when connecting a load to the
rear panel terminals. The flexible rear panel terminal
cover should be used when the load wiring becomes
too thick to be used with the PEL-012 terminal cover.
This is especially true when using the load generators
in parallel.
Warning
Ensure the power is off before making
any connections to the booster pack.
1. Wrap the insulation sheets around the terminals
and load cables, as shown below. Make sure the
terminals and any exposed wires are covered by the
sheets.

2. Secure the insulation sheets using the supplied
velcro fasteners. 2 fasteners should be used for each
sheet.

Connection
The PEL-3111(H) can control up to 4 PEL-3211(H)
booster units in parallel. Excluding the master unit,
other PEL-3000(H) units cannot be used in parallel
with the booster packs.
Master unit settings for response rate, response speed
and so on will be adopted by any connected booster
packs.
Note
Follow the procedures below for all
connections. Please adhere to the
following precautions to ensure your
safety and to protect the unit from
damage.
Caution
If the polarity to the input terminals is
reversed, the reverse voltage
protection function is tripped. The
reverse voltage protection function is
tripped when reverse voltages greater
than -0.3V are detected.
Ensure that the maximum input
voltage is not exceeded. The maximum
input voltage is 150 volts.
Warning
Do not touch any of the input
terminals when the unit is on.
Connecting the input terminals to the
wrong polarity can damage the DUT
or the booster packs/master unit.
Frame Link Connections
The J1 and J2 connectors on the rear panel are used to
control the booster packs for parallel operation. The
GTL-255 frame link cable is used to connect the J1 and
J2 connectors. The GTL-255 frame link cable is used for
units that are stacked vertically.
Note
Ensure that the frame link cables are
separated from the load cables as
much as possible for stable operation.
1. Make sure the master unit and booster packs are
turned off.
2. Make sure the DUT is turned off.
3. Connect the Master unit to the booster packs via the
J1/J2 connectors.
Use the GTL-255 frame link cable.
Connect from:
Master J2 to Slave1 J1
Slave1 J2 to Slave2 J1 and so on.
Remove the ferrite core that is attached to the J1
connector-side of the last frame link cable. See
the connection diagram for details.
Only the rear terminals on the master can be used for
parallel connections.
Make sure all connections are correct before turning on
the load. Incorrect connections could damage the units.
The booster packs should not be used in combination
with other PEL-3000(H) units as slaves other than the
PEL-3111(H) acting as the master.
Load Wire Connections
1. Make sure the master unit and booster packs are
turned off.
2. Make sure the DUT is turned off.
3. Connect the load units to the DUT.
Ensure the wire gauge is sufficient to handle the
increase in current.
Connect the rear negative terminals on the
booster(s) and master unit to the negative
potential of the DUT.
Connect the rear positive terminals on the
booster(s) and master unit to the positive
potential on the DUT.
If possible use the shortest cable length possible.
If possible, twist the load cable together to
reduce load line inductance.
Try to use cables of equal length.
Do not coil or loop the load cables.
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. Make sure the master unit and booster packs are
turned off.
2. Make sure the DUT is turned off.
Remote Sense Connections
3. Connect the sense cables from the DUT to the
master unit.
Connect a sense cable from the positive sense
terminal to the positive potential of the DUT.
Connect a sense cable from the negative sense
terminal to negative potential on the DUT.
Do not connect the sense cables to the booster
packs.
