SAFETY INSTRUCTIONS
This chapter contains important safety
instructions that you must follow during
operation and storage. Read the following before
any operation to insure your safety and to keep
the instrument in the best possible condition.
Safety Symbols
These symbols may appear in the 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 GPP or to other
properties.
DANGER High Voltage
Attention Refer to the Manual
Protective Conductor Terminal
Earth (ground) Terminal
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 unit.
Avoid severe impact or rough handling that
leads to damaging the unit.
Do not discharge static electricity to the unit.
Do not block the cooling fan opening.
Do not perform measurements on circuits that
are directly connected to mains power.
Do not disassemble the GPP unless you are
qualified.
(Measurement categories) EN 61010-1:2010
specifies the measurement categories and their
requirements as follows. The GPP Series 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.

(Pollution Degree) EN 61010-1:2010 specifies
pollution degrees and their requirements as
follows.Pollution refers to “addition of foreign
matter, solid, liquid, or gaseous (ionized gases),
that may produce a reduction of dielectric
strength or surface resistivity”. The GPP Series
falls under degree 2.
․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.
Power Supply
WARNING
AC Input voltage range:
100V/120V/220V/230V ±10%
Frequency: 50Hz/60Hz
To avoid electrical shock connect the protective
grounding conductor of the AC power cord to
an earth ground.
Fuse
WARNING
Fuse type: 100V/120V：T12A/250V，
220V/230V：T6.3A/250V
To prevent fire, replace the fuse only with the
specified type and rating.
Disconnect the power cord before replacing the
fuse.
Make sure the cause of fuse blowout is fixed
before replacing the fuse.

SAFETY INSTRUCTIONS

Cleaning the
power supply
Disconnect the power cord before cleaningit .
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid
into it.
Do not use chemicals containing harsh products
such as benzene, toluene, xylene, and acetone.
Operation

Power cord for the United Kingdom
When using the power supply 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.
