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 2260B or to other
properties.
DANGER High Voltage
Attention Refer to the Manual
Protective Conductor Terminal
Earth (ground) Terminal

SAFETY INSTRUCTIONS
5
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 2260B.
Avoid severe impact or rough handling that
leads to damaging the 2260B.
Do not discharge static electricity to the 2260B.
Use only mating connectors, not bare wires, for
the terminals.
Do not block the cooling fan opening.
Do not disassemble the 2260B unless you are
qualified.
(Measurement categories) EN 61010-1:2010 and EN 61010-2-030
specify the measurement categories and their requirements as
follows. The 2260B 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.
0 is for measurements performed on circuits not directly
connected to Mains.
Power Supply
WARNING
To avoid electrical shock connect the protective
grounding conductor of the AC power cord to
an earth ground.
Cleaning the
2260B
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 61010-1:2010 and EN 61010-2-030 specify the
pollution degrees and their requirements as follows. The 2260B 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: -15°Cto 70°C
Relative Humidity: <90%, no condensation
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 the power supply 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.
2260B Series Overview
Series lineup
The 2260B series consists of 12 models, divided into 3 different
model types covering 3 power capacities: 360W models, 720W
models and 1080W models.
Note
Throughout the user manual, 2260B-30, 2260B-80,
2260B-250 or 2260B-800 will refer to any of the
2260B models with a maximum voltage rating of
30V, 80V, 250V or 800V, respectively.
