SAFETY INSTRUCTION

This chapter contains important safety instructions that should be followed when operating and storing the oscilloscope. Read the following before any operation to ensure your safety and to keep best condition for the oscilloscope.

Safety Symbols

These safety symbols may appear in this manual or on the oscilloscope.

WARNING

CAUTION

Warning: Identifies conditions or practices that could result in injury or loss of life.

Caution: Identifies conditions or practices that could result in damage to the oscilloscope or to other objects or property.

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 heavy objects on the oscilloscope.

∙Avoid severe impacts or rough handling that may damage the oscilloscope.

∙Avoid discharges of static electricity on or near the oscilloscope.

∙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).

∙The oscilloscope should only be disassembled by a qualified technician.

(Measurement categories) EN 61010-1:2001 specifies the measurement categories and their requirements as follows. The DSO-4000 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.

Power Supply	∙ AC Input voltage: 100 ~ 240V AC, 47 ~ 63Hz
WARNING	∙ The power supply voltage should not fluctuate
	more than 10%.
	∙ Connect the protective grounding conductor of
	the AC power cord to an earth ground.

(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees and their requirements as follows. the oscilloscope 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, nonconductive 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 cord for the United Kingdom

When using the oscilloscope 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 rewiring must be carried out in accordance with the information detailed on this label.
