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

SAFETY INSTRUCTIONS

3

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.

2260B Series Programming Manual

4

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.

SAFETY INSTRUCTIONS

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 0.75mm

2

should 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.

2260B Series Overview

Series lineup

The 2260B series consists of 4 models, divided into 2 different
model types covering 2 power capacities: 360W models and 720W
models.

Model name Type Voltage rating Current rating Power

2260B-30-36 360W models 0~30V 0~36A 360W

2260B-80-13 360W models 0~80V 0~13.5A 360W

2260B-30-72 720W models 0~30V 0~72A 720W

2260B-80-27 720W models 0~80V 0~27A 720W

Apart from the differences in output, each unit differs in size. The
720W models are larger than the 360W models to accommodate the
increase in power.

Configure GPIB Interface

To use GPIB, the optional GPIB to USB adapter (2260B-GPIB-USB)
must be used. The GPIB to USB adapter must be connected before
the 2260B is turned on. Only one GPIB address can be used at a
time.

Configure GPIB

1. Ensure the 2260B is off before proceeding.

2. Connect the USB cable from the rear panel

USB B port on the 2260B to the USB A port on
the GPIB to USB adapter.

3. Connect a GPIB cable from a GPIB controller to

the GPIB port on the adapter.

• Maximum 15 devices altogether, 20m cable

length, 2m between each device

• Unique address assigned to each device

• At least 2/3 of the devices turned On

• No loop or parallel connection

REMOTE CONTROL

Configure Ethernet Connection

The Ethernet interface can be configured for a number of different
applications. Ethernet can be configured for basic remote control or
monitoring using a web server or it can be configured as a socket
server.

The 2260B series supports DHCP connections so the instrument can
be automatically connected to an existing network or alternatively,
network settings can be manually configured.
