These safety symbols may appear in this manual or on PSH.
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 PSH or to other
properties.
DANGER High Voltage
Attention Refer to Manual
Protective Conductor Terminal

Safety Guidelines
• Do not place any heavy object on PSH.
• Avoid severe impacts or rough handling that
leads to damaging PSH.
• Do not discharge static electricity to PSH.
• Do not block or obstruct cooling fan vent
opening.
• Do not perform measurements at power source
and building installation site (Note below).
• Do not disassemble PSH unless you are
qualified as service personnel.
General
Guideline
CAUTION
(Note) EN 61010-1:2001 specifies the measurement
categories and their requirements as follows. PSH 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.
Power Supply
WARNING
• Input voltage: 90 ~ 250 V AC, 50/60 Hz
• The power supply voltage should not fluctuate
more than 10%.
• Connect the protective grounding conductor of
the power cord to earth ground, to avoid
electrical shock.

Fuse
WARNING
• Make sure the correct type of fuse is installed
before powering up.
• Replace the fuse with the specified type and
rating only, for continued fire protection.
• Disconnect the power cord before fuse
replacement.
• Make sure the cause of the fuse blowout is
fixed before fuse replacement.
Cleaning PSH
• Disconnect the power cord before cleaning.
• Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid
into PSH.
• Do not use chemicals or cleaners containing
harsh materials such as benzene, toluene,

almost non-conductive pollution (Note below)
Relative Humidity: < 85%
Altitude: < 2000m

case, take adequate measures.
Operation
Environment
WARNING
(Note) EN 61010-1:2001 specifies the pollut ion degrees
and their requirements as follows. PSH 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 wi nd
pressure, but neither temperature nor humidity is
controlled.

Power cord for the United Kingdom
When using PSH in the United Kingdom, make sure the power
cord meets the following safety instructions.
NOTE: This lead / appliance must only be wired by competent pe rsons
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 corr espond with the colours
marking identified in your plug/appliance, proceed as follows:
The wire which is coloured Green & Yellow must be con nected to the Earth
terminal marked with the letter E or by the ea rth 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 Brow n 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 infor mation 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 re quire 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
re-wiring must be carried out in accordance with the information detailed o n
this label.
PSH Overview

PSH Overview
PSH Series are modular-type programmable
switching power supplies designed for broad
range of applications. The series consists of 12
models, output ranging from 360W to 1000W.
Switching technology and built-in PFC control
give PSH higher power efficiency, power density,
and power factor compared with other linear
power supplies. Protection mechanisms keep the
output voltage, current, and temperature within
limit. Remote control interface equipped with
SCPI command set and Lab-View Driver
facilitates ATE software development.
This chapter describes PSH series features and
appearances in a nutshell.
