WARNING
AC Input voltage range: 100-120VAC/200-
240VAC
(90-132VAC/180-250VAC)
Frequency: 47-63Hz
Power:
PEL-3211(H): 230VA Max
To avoid electrical shock connect the protective
grounding conductor of the AC power cord to
an earth ground.
Cleaning
Disconnect the power cord before cleaning.
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid.
Do not use chemicals containing harsh material
such as benzene, toluene, xylene, and acetone.

(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
and their requirements as follows. The instrument falls under
degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or
gaseous (ionized gases), that may produce a reduction of dielectric
strength or surface resistivity”.
Pollution degree 1: No pollution or only dry,
non-conductive pollution occurs. The pollution
has no influence.
Pollution degree 2: Normally only non-
conductive pollution occurs. Occasionally,
however, a temporary conductivity caused by
condensation must be expected.
Pollution degree 3: Conductive pollution occurs,
or dry, non-conductive pollution occurs which
becomes conductive due to condensation which
is expected. In such conditions, equipment is
normally protected against exposure to direct
sunlight, precipitation, and full wind pressure,
but neither temperature nor humidity is
controlled.
Storage

Location: Indoor
Temperature: -20°C to 70°C
Humidity: <90% RH
Disposal
Do not dispose this instrument as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased. Please make sure
discarded electrical waste is properly recycled to
reduce environmental impact.

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 0.75mm2should 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.

PEL-3211(H) Booster Pack Introduction
The PEL-3211(H) Booster is designed to be used with the PEL-
3111(H) Electronic Load for parallel load applications to increase
the current sinking capacity. Up to 4 booster packs can be
connected as slave units to a PEL-3111(H), which acts as the master
unit.
Please note that throughout this manual the term “PEL-3000(H)”
refers to any one of the models in the series lineup, unless
specifically stated otherwise. The termer “booster” refers only to
the PEL-3211(H). The term “master” or “master unit” refers to the
PEL-3111(H) unit that is configured as the master unit when in
parallel mode.

Load Wiring
Wire Gauge
considerations
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
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 table below
to help make a suitable selection.
