SAFETY INSTRUCTIONS

This chapter contains important safety

instructions that you must follow during

operation and storage. Read the following before

any operation to insure your safety and to keep

the instrument in the best possible condition.

Safety Symbols

These safety symbols may appear in this manual or on the

instrument.

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 the instrument or to

other properties.

DANGER High Voltage

Attention Refer to the Manual

Protective Conductor Terminal

Earth (ground) Terminal

2260B Series User Manual

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

 Do not place any heavy object on the

instrument.

 Avoid severe impact or rough handling that

leads to damaging the instrument.

 Do not discharge static electricity to the

instrument.

 Use only mating connectors, not bare wires, for

the terminals.

 Do not block the cooling fan opening.

 Do not disassemble the instrument unless you

are qualified.

(Measurement categories) EN 61010-1:2001 specifies the

measurement categories and their requirements as follows. This

instrument 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

WARNING

 AC Input voltage range: 85VAC~265VAC

 Frequency: 47Hz~63Hz

 To avoid electrical shock connect the protective

grounding conductor of the AC power cord to

an earth ground.

SAFETY INSTRUCTIONS

Cleaning the

Instrument

 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 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: 20%~ 85%

 Altitude: < 2000m

 Temperature: 0°C to 50°C

(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees

and their requirements as follows. The Instrument 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

 Temperature: -25°C to 70°C

 Relative Humidity: <90%

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.

2260B Series User Manual

Power cord for the United Kingdom

When using the instrument 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 coloured 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 either the letter E, the earth symbol

or coloured Green/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, a 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 exposed wiring from a cable, plug or connection that is

engaged in a live socket is extremely hazardous. If a cable or plug is

deemed hazardous, turn off the mains power and remove the cable,

any fuses and fuse assemblies. All hazardous wiring must be

immediately destroyed and replaced in accordance to the above

standard.

GETTING STARTED

This chapter describes the power supply in a

nutshell, including its main features and front /

rear panel introduction. After going through the

overview, please read the theory of operation to

become familiar with the operating modes,

protection modes and other safety considerations.
