1 Safety Advice

1.1 General Advice

General

This manual contains basic advice for the installation and operation of

the product. It is essential to make this manual accessible to the

authorised and skilled operator. He needs to read this manual closely.

The manufacturer is not liable for damage to material or humans due to

neglectance of this manual and this and the following safety advices.

Setting up and operating the instrument may only be done by authorised

and skilled personnel. According to DIN VDE 0104 (EN 50191) and DIN

VDE 0105 (EN 50110) as well as the accident prevention regulation

(Unfallverhütungsvorschrift UVV), skilled personnel is defined as a

person who is qualified to work, judge and realize dangers due to his

professional education, knowledge and experience and his knowledge

of applicable regulations. Locally applying regulations have to be

observed.

Working with equipment of Megger

All electrical regulations of the country where the instrument is operated

have to be observed as well as national regulations for prevention of

accidents and existing regulations for the safety and operation of

equipment of the involved companies. After working with the equipment,

make sure to de-energise, protect against re-

energising, discharge,

ground and short-circuit the instrument and installations that have been

worked on. Original accessories ensure safe operation of the equipment.

It is not allowed and the warranty is lost if other accessories than the

original ones are used with the equipment. Repairs and service must

only be done by Megger or authorised service departments of Megger.

Megger recommends having the equipment serviced and checked once

per year at a Megger service location.

Intended application

Safe operation is only realised when

using the equipment for its

intended purpose (see chapter "Introduction"). Using the equipment for

other purposes may lead to human danger and damage of equipment of

involved installations. The limits described under technical data may not

be exceeded. Operating products of Megger in condensing environment

may lead to flash-over, danger and damage. The instruments should

only be operated under tempered conditions. It is not allowed to operate

Megger

products at direct contact with humidity, water or near

aggressive chemicals nor explosive gases and fumes.

Behaviour at malfunction of normal operation

The equipment may only be used when working properly. When

irregularities or malfunctions appear that cannot be solved consulting

this manual, the equipment must immediately be put out of operation

and marked as not functional. In this case inform the person in charge

who should inform the Megger

service to resolve the problem. The

instrument may only be operated when the malfunction is resolved.

Operation in traffic environment

To ensure safety for operators and traffic, the country-specific

regulations must be observed.

Transport and operating position

The device may only be operated and transported in an upright

(standing) position!

Using cardiac pacemaker

Physical processes during operation of high voltage may endanger

persons wearing a cardiac pacemaker when near these high voltage

facilities.

Fire fighting in electrical installations

Recommended extinguishing agent: carbon dioxide (CO2)

Carbon dioxide is electrically non conductive and does not leave

residue. It is safe to use in energized facilities as long as the

minimum distances are observed.

It is essential to observe the safety instruction on the extinguishing

agent.

Applicable is DIN VDE 0132.

1.2 Electrical Advice

Dangers when operating with high voltage

Special attention and safety-

conscious behaviour is needed when

operating high voltage facilities and especially non-stationary equipment.

The regulations VDE 0104 about setting up and operation of electric test

equipment, i.e. the corresponding EN 50191 as well as country-specific

regulations and standards must be observed.

Advice about handling high voltage

Safety installations may not be by-passed nor deactivated.

Operation req

uires minimum two people whereas the second person

must be able to activate the emergency-OFF button in case of danger.

To avoid hazardous electric charges of metallic parts in the vicinity, all

metallic parts must be grounded.

To avoid drawing dangerous a

rcs, switching should only be done in

de-energized condition.

HV test equipment and burn-down equipment is short-

circuit proof.

Hazardous voltage may be present if a short circuit is opened during

operation. If measuring short-circuit current is necessary, it is advisable

to connect an arrester in parallel with the measuring instrument (e.g.

90 V glow arrester).

Adequate safety precautions must be met when using transient

measuring techniques, using HV test instruments or surge generators.

The equipment an

d all accessories must be connected according to

applicable standards VDE, EN or DIN as well as country-specific

regulations.

Always follow the 5 Safety Rules !

These five safety rules must always be followed when working

with high voltage:

1. De-energise

2. Protect against re-energising

3. Confirm absence of voltage

4. Ground and short-circuit

5. Cover up or bar-off neighbouring energised parts
