SAFETY INSTRUCTIONS
This chapter contains important safety
instructions that you must follow during
operation and storage. Read the following before
any operation to ensure your safety and to keep
the instrument in the best possible condition.
Safety Symbols
These safety symbols may appear in this manual or on the
instrument.
WARNING
Warning: Identifies conditions or practices that
could result in injury or loss of life.
CAUTION
Caution: Identifies conditions or practices that
could result in damage to the GPT-9000 or to other
properties.

Do not dispose electronic equipment as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased.
Safety Guidelines
General
Guideline
CAUTION
Do not place any heavy object on the GPT-9000.
Avoid severe impact or rough handling that
leads to damaging the GPT-9000.
Do not discharge static electricity to the GPT-
9000.
Use only mating connectors, not bare wires, for
the terminals.
Do not block the cooling fan opening.
Do not disassemble the GPT-9000 unless you are
qualified.
(Measurement categories) EN 61010-1:2010 specifies the
measurement categories and their requirements as follows. the GPT
falls under category I.
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.
Measurement category I is for measurements performed on
circuits not directly connected to Mains.
Power Supply
WARNING
AC Input voltage range:
100/120/220/230VAC ±10%
Frequency: 50Hz/60Hz
To avoid electrical shock connect the protective
grounding conductor of the AC power cord to
an earth ground.

SAFETY INSTRUCTIONS

Cleaning the
GPT-9000
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)
Relative Humidity: ≤70% (no condensation)
Altitude: < 2000m
Temperature: 0˚C~40˚C
(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
and their requirements as follows. The GPT-9000 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: -10°C to 70°C
Relative Humidity: ≤ 85% (no condensation)
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 safety tester 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.

GPT-9000 Series Overview
Series lineup
The GPT-9000 Series Safety Testers are AC/DC withstanding
voltage, insulation resistance and ground bond safety testers. The
GPT-9801 is an AC withstanding voltage tester, the GPT-9802 is an
AC/DC withstanding voltage tester and the GPT-9803 is an
AC/DC withstanding voltage and insulation resistance tester. The
GPT-9804 includes all the functions of the other models as well as
ground bond testing. All models can operate at up to 5kVAC for
AC withstanding voltage testing. The GPT-9802, GPT-9803 and
GPT-9804 can also operate at up to 6kVDC for DC withstanding
voltage testing.
The GPT-9000 Series can store up to 100 manual tests, as well as
run up to 16 manual tests sequentially as an automatic test,
allowing the safety testers to accommodate any number of safety
standards, including IEC, EN, UL, CSA, GB, JIS and others.
