Safety Guidelines
General
Guideline
CAUTION
Do not place any heavy object on the
instrument. Note: Only 2 units can be stacked
vertically.
Avoid severe impact or rough handling that
leads to damaging the instrument.
Do not discharge static electricity to the
instrument.
Use only crimped wires, not bare wires, for the
terminals.
Do not block the cooling fan opening.
Do not disassemble the instrument unless you
are qualified.
The equipment is not for measurements
performed for CAT II, III and IV.
(Measurement categories) EN 61010-1:2010 specifies the
measurement categories and their requirements as follows.
Measurement category IV is for measurement
performed at the source of low-voltage
installation.
Measurement category III is for measurement
performed in the building installation.
Measurement category II is for measurement
performed on the circuits directly connected to
the low voltage installation.
0 is for measurements performed on circuits not
directly connected to Mains.
Do NOT position the equipment so that it is
difficult to disconnect the appliance inlet or the
power plug.
If the equipment is used in a manner not
specified by the manufacturer, the protection
provided by the equipment may be impaired.

Power Supply
WARNING
AC Input voltage range: 100-120VAC/200-
240VAC
(90-132VAC/180-250VAC)
Frequency: 47-63Hz
Power:
PEL-3021(H): 90VA Max
PEL-3041(H): 110VA Max
PEL-3111(H): 190VA Max
PEL-3211(H): 230VA Max
To avoid electrical shock connect the protective
grounding conductor of the AC power cord to
an earth ground.
To avoid electric shock, the power cord
protective grounding conductor must be
connected to ground. No operator serviceable
components inside. Do not remove covers.
Refer servicing to qualified personnel.
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.
Operation
Environment
Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
Temperature: 0°C to 40°C
Humidity: 0 to 85% RH
Altitude: <2000m
Overvoltage category II

PEL-3000(H) User Manual

(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
environment
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.

PEL-3000(H) Series Introduction
The PEL-3000(H) Series is a family of high performance DC
electronic loads positioned to test a wide range of different power
sources. The DC electronic loads are fully programmable to
simulate anything from basic static loads to complex dynamic loads.
With the ability to operate independently or in parallel, the PEL-
3000(H) Series is extremely robust and capable of molding to any
test environment.
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.
