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. The
instrument falls under category II.
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.

Power Supply
WARNING
AC Input voltage range: 100-120VAC/200-
240VAC
(90-132VAC/180-250VAC)
Frequency: 47-63Hz
Power:
PEL-3021: 90VA Max
PEL-3041: 110VA Max
PEL-3111: 190VA Max
PEL-3211: 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.
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

PEL-3000 User Manual
6
(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.

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.
