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 PSW-Multi or to
other properties.
DANGER High Voltage
Attention Refer to the 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 PSW-
Multi.
Avoid severe impact or rough handling that
leads to damaging the PSW-Multi.
Do not discharge static electricity to the PSW-
Multi.
Use only mating connectors, not bare wires, for
the terminals.
Do not block the cooling fan opening.
Do not disassemble the PSW-Multi unless you
are qualified.
Power Supply
WARNING
AC Input voltage rating: 100Vac-240Vac +/-10%
Frequency: 47Hz~63Hz
To avoid electrical shock connect the protective
grounding conductor of the AC power cord to
an earth ground.
Cleaning the
PSW-Multi
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

SAFETY INSTRUCTIONS
7
Temperature: 0°C to 50°C
Mains supply voltage fluctuations: +/-10 %
Overvoltage category: OVC II
If the equipment is used in a manner not
specified by the manufacturer, the protection
provided by the equipment may be impaired.
LAN, RS232/RS485, USB, and GPIB ports are
only to be connected to the circuits which are
separated from mains supply by double /
reinforce insulation.
(Pollution Degree) EN 61010-1 and EN 61010-2-030 specify the
pollution degrees and their requirements as follows. The PSW 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%, 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.
All hazardous wiring must be immediately destroyed and replaced
in accordance to the above standard.

PSW-Multi Series Overview
Series lineup
The PSW-Multi series consists of 37 models divided into 2 output
terminal type (Busbar and connector type) with 2 different size
model types (PSW-720 and PSW-1080). The PSW-720 is 2 channel
output type and PSW-1080 is 3 channel output type. The models of
busbar output type are PSW 30, PSW 40, PSW 80 and PSW160 and
connector type are PSW 250 and PSW 800.
Note
Throughout the user manual, PSW 30, PSW 40, PSW
80, PSW 160, PSW 250, PSW 800 will refer to any of
the PSW models with a maximum voltage rating of
30V, 40V, 80V, 160V, 250V or 800V, respectively.
Each channel of PSW-Multi series doesn't support
serial or parallel operation.
