SAFETY INSTRUCTIONS

This chapter contains important safety
instructions that you must follow when operating
a PSP series power supply and when keeping it in
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 power
supply.

SAFETY INSTRUCTIONS

General
Guideline

CAUTION

 Do not place any heavy object on the power

supply.

 Avoid severe impact or rough handling that

could lead to damaging the power supply.

 Do not discharge static electricity to the power

supply.

 Do not block or obstruct the cooling fan vent

openings.

 Do not disassemble the power supply unless

you are qualified as service personnel.

(Measurement categories) EN 61010-1:2001 specifies the
measurement categories and their requirements as follows. The
PSP series power supplies fall 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: 115/230 VAC±15%.
 Connect the protective grounding conductor of

the AC power cord to an earth ground, to avoid
electrical shock.

Fuse

WARNING

 Fuse type: Slow blow T3.15A/250V (230V

input), T6.3A/250 (115V input).

 Make sure the correct type of fuse is installed

before power up.

PSP Series User Manual

 For fire prevention, replace the fuse only with

the specified type and rating.

 Disconnect the power cord before fuse

replacement.

 Make sure the cause of the fuse blowout is fixed

before replacing the fuse.

Cleaning

 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 or cleaners containing

harsh materials such as benzene, toluene,
xylene, and acetone.

Operation
Environment

 Location: Indoor, no direct sunlight, dust free,

almost non-conductive pollution (Note below)

 Relative Humidity: < 80%
 Altitude: < 2000m
 Temperature: 0°C to 40°C

(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees
and their requirements as follows. The PSP power supply 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.

SAFETY INSTRUCTIONS

Storage
environment

 Location: Indoor
 Relative Humidity: < 80%
 Temperature: −10°C to 70°C

General
Precautions

CAUTION

 All electronically conducting materials (cables,

leads, terminals) must be sufficiently insulated.

 Connected loads should not be left

unsupervised.

 Ensure adequate ventilation for operation.
 High voltages or current can be hazardous,

ensure proper safety precautions are used.

 Do not use the power supply in situations

where condensation may have occurred, such as
where severe temperature/humidity
fluctuations have occurred.

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:

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

0.75mm2 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.
