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 device.
Avoid severe impacts or rough handling that
leads to damaging the device.
Do not discharge static electricity to the device.
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 device unless you are
qualified as service personnel.
(Measurement categories) EN 61010-1:2010 specifies the
measurement categories and their requirements as follows. The
GPE-1326/2323/3323/4323 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±10%, 230VAC +10%/-6%,
50/60Hz
Connect the protective grounding conductor of
the AC power cord to an earth ground, to avoid
electrical shock.

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
device
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

(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
and their requirements as follows. The GPE-1326/2323/3323/4323
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.

Power cord for the United Kingdom
When using the GPE-1326/2323/3323/4323 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.

OVERVIEW
This chapter describes the GPE-1326/ 2323/ 3323/
4323 series in a nutshell, including its main
features and front/ rear panel introduction. After
going through the overview, follow the Setup
chapter (page 25) to properly power up and set
operation environment.
Introduction
Overview
The GPE-1326/2323/3323/4323 series regulated
DC power supply series are light weight,
adjustable, multifunctional work stations. The
GPE-1326 has a single independent adjustable
voltage output (Coarse and fine). The remote
voltage compensation function is activated for
large changes in current output. The GPE-2323 has
a 2 independent adjustable voltage outputs. The
GPE-3323 has three independent outputs: two with
adjustable voltage levels and one with fixed level
5V. The GPE-4323 has four independent voltage
outputs that are all fully adjustable. The 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.
