SAFETY INSTRUCTIONS
SAFETY INSTRUCTIONS
This chapter contains important safety instructions
that you must follow when operating the GPD-
X303S series and when keeping it in storage. Read
the following before any operation to insure your
safety and to keep the best condition for the GPD-
X303 series.
Safety Symbols
These safety symbols may appear in this manual or on the GPD-
X303S series.
WARNING Warning: Identifies conditions or practices that
could result in injury or loss of life.

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
Guidelines
CAUTION
•Do not place any heavy object on the GPD-
X303S series.
•Avoid severe impacts or rough handling that
leads to damaging the GPD-X303S series.
•Do not discharge static electricity to the GPD-
X303S series.
•Do not block or obstruct the cooling fan vent
opening.
•Do not perform measurement at circuits directly
connected to Mains (see note below).
•Do not disassemble the GPD-X303S series unless
you are qualified as service personnel.
(Measurement categories) EN 61010-1:2001 specifies the
measurement categories and their requirements as follows. The
GPD-X303S 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.
Power Supply
WARNING
•AC Input voltage: 100V/120V/220V/230V
±10%, 50/60Hz
•Connect the protective grounding conductor of
the AC power cord to an earth ground, to avoid
electrical shock.

SAFETY INSTRUCTIONS
Fuse
WARNING
•Fuse type: 100V/120V: T6.3A/250V,
220V/230V: T3.15A/250V
•Make sure the correct type of fuse is installed
before power up.
•To ensure fire protection, replace the fuse only
with the specified type and rating.
•Disconnect the power cord before fuse
replacement.
•Make sure the cause of fuse blowout is fixed
before fuse replacement.
Cleaning the
GPD-X303S
series
•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 or cleaners containing
harsh products such as benzene, toluene, xylene,
and acetone.
Operation
Environment
•Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (note below)
•Relative Humidity: < 80%
•Altitude: < 2000m
•Temperature: 0°C to 40°C

GPD-X303S Series User Manual
(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees
and their requirements as follows. The GPD-X303S series 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
•Relative Humidity: < 70%
•Temperature: −10°C to 70°C
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.

SAFETY INSTRUCTIONS
Power cord for the United Kingdom
When using the GPD-2303S/GPD-3303S/GPD-4303S series 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 colours
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 the letter E or by the earth symbol or coloured Green or
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, 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 moulded mains connector that requires removal /replacement must be
destroyed by removal of any fuse & fuse carrier and disposed of immediately, as
a plug with bared wires is hazardous if a engaged in live socket. Any re-wiring
must be carried out in accordance with the information detailed on this label.

GPD-X303S Series User Manual
OVERVIEW
This chapter describes the GPD-2303S/GPD-
3303S/GPD-4303S series in a nutshell, including
its main features and front / rear panel
introduction. After going through the overview,
follow the Setup chapter (page23) to properly
power up and set operation environment.
Introduction
Overview The GPD-X303S regulated DC power supply series
are light weight, adjustable, multifunctional work
stations. The GPD-2303S has a 2 independent
adjustable voltage outputs. The GPD-3303S three
independent outputs: two with adjustable voltage
levels and one with fixed level selectable from
2.5V, 3.3V and 5V. The GPD-4303S has four
independent voltage outputs that are all fully
adjustable. The GPD-X303S series can be used for
logic circuits where various output voltage or
current are needed, and for tracking mode
definition systems where plus and minus voltages
with insignificant error are required.
