Safety Guidelines

General

Guideline

CAUTION

6

•Make sure the BNC input voltage does not exceed 300Vpeak.

•Never connect a hazardous live voltage to the ground side of the BNC connectors. It might lead to fire and electrical 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 or obstruct cooling fan vent

Safety Instructions

opening.

•Do not perform measurements at power source and building installation site (Note below).

•Do not disassemble GDS-2000 unless you are qualified as service personnel.

(Note) 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.

Power Supply

WARNING

•Input voltage: 100 ~ 240 V AC, 48 ~ 63Hz

•The power supply voltage should not fluctuate more than 10%.

•Connect the protective grounding conductor of the power cord to earth ground, to avoid electrical shock.

Fuse

WARNING

•Fuse type: T2A/ 250V

•Make sure the correct type of fuse is installed before powering up.

•Replace the fuse with the specified type and rating only, for continued fire protection.

•Disconnect the power cord before fuse replacement.

•Make sure the cause of the 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

		into GDS-2000.
		• Do not use chemicals or cleaners containing
		harsh materials such as benzene, toluene,
		xylene, and acetone.
	Operation	Location: Indoor, no direct sunlight, dust free,
	Environment	almost non-conductive pollution (Note below)
		Relative Humidity: < 80%
		Altitude: < 2000m
		Temperature: 0°C to 50°C
		(Note) EN 61010-1:2001 specifies the pollution

		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.

Safety Instructions

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:

Blue: Brown:

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.
