Note

Please observe!

Opening of Equipment / Repair

The equipment may be opened only by authorized service per-

sonnel to ensure the safe and correct operation of the equipment

and to keep the warranty valid.

Even original spare parts may be installed only by authorized ser-

vice personnel.

In case the equipment was opened by unauthorized personnel,

no warranty regarding personal safety, measurement accuracy,

conformity with applicable safety measures or any consequential

damage is granted by the manufacturer.

Measuring Categories and their Significance per IEC 61010-1

CAT Definition

3 Introduction

These operating instructions contain information and directions

which are necessary for safe operation and use of the instrument.

Before using the instrument, the operating instructions must be

carefully read and all points contained therein must be followed

correctly. Non-observance of the operating instructions, as well

as warnings and directions included therein, may result in severe

injury to the user or damage to the instrument.

The

PROFITEST PV

SUN

is used for simple testing of solar cells and

modules. The terms used in these operating instructions to desig-

nate systems for generating electrical power from sunlight include:

solar system, photovoltaic system, PV system and the like.

Scope of Functions

• Voltage measurement to 1000 V DC

• Short circuit current measurement to 20 A DC

• Selection of insulation test voltage: 250, 500 or 1000 V DC

• Insulation measurement to 20 MΩ with display of limit value

• Testing of protective conductor continuity

• Earth fault measurement

• Polarity check

• Backlit LCD panel

• Optional temperature measurement

4 Transport and Storage

Please retain the original packaging for subsequent shipment of

the instrument. Transport damages due to inadequate packaging

are excluded from the guarantee.

The instrument may only be stored in dry, closed rooms.

If the instrument is subjected to extreme temperature during

transport, it requires at least 2 hours for acclimatization before it is

switched on.

5 Safety Precautions

The instrument has been manufactured and tested in accordance

with IEC/EN 61010-1, “Safety requirements for electrical equip-

ment for measurement, control and laboratory use”, and has been

shipped from the factory in flawless technical safety condition. In

order to assure that this condition is retained, the user must

observe the safety precautions included in these operating

instructions.

Caution! Dangerous Voltage

In order to prevent electrical shock, corresponding safety

precautions must be implemented when working with

voltages of greater than 120 V (60 V) DC or 50 V (25 V)

AC TRMS. In accordance with DIN VDE, these values

specify the limit for exposed (touchable) voltages (the val-

ues in parentheses apply to, for example, the fields of

medicine and agriculture).

Before each measurement, make sure that the measurement

cables and the measuring instrument are in flawless condition.

The measuring instrument may only be used within the specified

measuring ranges.

If the safety of the user is no longer assured, the instrument must

be removed from service and secured against unintentional use.

Safety of the user is no longer assured if the instrument:

• Demonstrates apparent damage

• No longer performs the desired measurements

• Has been stored for too long under unfavorable conditions

• Has been subjected to mechanical stressing during transport

The instrument may not be opened, dismantled or modified in any

way. The instrument may only be used with recommended

accessories. The use of unsuitable accessories is impermissible.

Trade association accident prevention regulations for electrical

systems and operating equipment must be adhered to during all

work with the instrument.

Do not allow the instrument to warm up due to exposure to direct

sunlight. Flawless functioning and a long service life cannot other-

wise be assured.

Attention!

The internal warming of the test instrument is measured

electronically. An inpermissible overheating is signalled

by ISC and °C in the display while further measurements

are being disabled. Allow the test instrument to cool

down before continuing measurements.

6 Use for Intended Purpose

The instrument may only be used under the conditions and for the

purposes for which it has been designed. In this respect, special

attention must be given to safety precautions, technical data

regarding ambient conditions and use in a dry environment.

Warning!

The instrument may not be operated at measuring cate-

gory II, III and IV mains power circuits.

In accordance with EN 61010-1:2010, the instrument

has been designed without a rated measuring category,

and may only be used at direct voltage circuits with up to

1000 V without transient overvoltages.

Operating safety is no longer assured in the event of modification

or alteration. The instrument may only be opened by authorized

service technicians.

Never operate the instrument at a higher voltage than specified in

the technical data! The instrument may otherwise be destroyed or

permanently damaged.
