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 PPX or to other

properties.

DANGER High Voltage

Attention Refer to the Manual

Protective Conductor Terminal

Earth (ground) Terminal

SAFETY INSTRUCTIONS

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 PPX.

Avoid severe impact or rough handling that

leads to damaging the PPX.

Do not discharge static electricity to the PPX.

Use only mating connectors, not bare wires, for

the terminals.

Do not disassemble the PPX unless you are

qualified.

Power Supply

CAUTION

WARNING

AC Input Voltage:

100Vac/120Vac/220Vac/240Vac, 50Hz/60Hz,

single phase

Frequency: 47Hz to 63Hz

Before connecting the power plug to an AC line

outlet, make sure the voltage selector switches

of the bottom panel in the correct position.

Disconnect power cord and test leads before

replacing fuse.

The fuse specification is as following:

To avoid electrical shock connect the protective

grounding conductor of the AC power cord to

an earth ground.

PPX Series Programming Manual

Cleaning the PPX

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%~ 80% (no condensation)

Altitude: < 2000m

Temperature: 0°C to 40°C

(Pollution Degree) EN61010-1:2010 specifies the pollution degrees

and their requirements as follows. The PPX 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: -20°C to 70°C

Relative Humidity: 20 to 85%(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.

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.
