SAFETY INSTRUCTIONS
This chapter contains important safety
instructions that you must follow when operating
GDS-2000 and when keeping it in storage. Read
the following before any operation to insure your
safety and to keep the best condition for GDS-
2000.
Safety Symbols
These safety symbols may appear in this manual or on GDS-2000.
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 GDS-2000 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
Make sure the BNC input voltage does not
exceed 300V peak.
Never connect a hazardous live voltage to the
ground side of the BNC connectors. It might
lead to fire and electric shock.
Do not place any heavy object on GDS-2000.
Avoid severe impacts or rough handling that
leads to damaging GDS-2000.
Do not discharge static electricity to GDS-2000.
Use only mating connectors, not bare wires, for
the terminals.
Do not block the cooling fan opening.
Do not perform measurement at power source
and building installation site (Note below).
Do not disassemble GDS-2000 unless you are
qualified.
(Measurement categories) EN 61010-1:2001 specifies the
measurement categories and their requirements as follows. GDS-
2000 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.
Measurement category I is for measurements performed on
circuits not directly connected to Mains.

SAFETY INSTRUCTIONS

Power Supply
WARNING
AC Input voltage: 100 ~ 240V AC, 48 ~ 63Hz
The power supply voltage should not fluctuate
more than 10%.
Connect the protective grounding conductor of
the AC power cord to an earth ground, to avoid
electrical shock.
Fuse
WARNING
Fuse type: T2A/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 GDS-
2000
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 chemical 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: ≤80%, 40°C or below
≤45%, 41°C~50°C
Altitude: < 2000m
Temperature: 0°C to 50°C

GDS-2000 Series User Manual

(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees
and their requirements as follows. GDS-2000 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
Storage Temperature: -10°C~60°C, no
condensation-
Relative Humidity: 93% @ 40°C
65% @ 41°C ~60°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 GDS-2000 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 0.75mm2 should 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.
