1 Safety Advice
1.1 General Notes
Safety precautions This manual contains basic advice for the installation and operation of the Easytest. 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 non-observance of the instructions and safety advices
provided by this manual.
Locally applying regulations have to be observed!
Symbols used in this
manual
Important instructions concerning the protection of staff and equipment as well as
technical safety within this document are labelled with one of the following symbols:
Symbol Description
Indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided, may
result in minor or moderate injury or material damage.
Notes have important information and useful tips on the operation of
your equipment. Non-observance may result in useless measure-
ment results.
Working with equipment
of Megger
All electrical regulations of the country where the system 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.
Operating personal Only trained and/or instructed staff is permitted to deal with this syste
m and its
peripherals. Keep any other person away from it.
Only authorised persons with sufficient expertise are allowed to operate the device.
Repair and maintenance 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.
Megger also offers direct on-site support. Please contact our service office for more
information.
WARNING
CAUTION

1-7
1.2 General Cautions and Warnings
Intended application Safe operation is only realised when using the equipment for its intended purpose
(see chapter 2.3 Functional Description). 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.
Fife safety rules
The five safety rules must always be followed when working with HV (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
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.

1-8
Be careful when working with high voltage
Working on high voltage systems and equipment – especially in non-stationary
operation – requires particular care and safety-
conscious action on the part of test
personnel. VDE regulations 0104 on setting up and operating electrical test systems,
as well as EN 50191 and national standards and regulations must be strictly adhered
to.
•The Easytest generates a dangerous voltage of up to 20 kV during testing. This
is supplied via a HV cable to the test object.
•The test system may not be operated without supervision.
•When the test system in use, a second person must always be within sight and
calling distance, in order to use the emergency off switch in the event of danger.
•Never fail to use safety equipment or put it out of operation.
•To prevent dangerous charge accumulation, earth all metal parts in the vicinity of
the high voltage equipment.
•All ca
bles which are out of operation and not tested must be shorted and
earthed.
•The system and all auxiliary equipment must be connected in accordance with
the regulations. The applicable EN, DIN, VDE and national standards and regu-
lations must be strictly adhered to.
•Check whether there are any unsecured live systems or components in the im-
mediate vicinity of the test system which might you or the system might
accidentally come into contact with. This particularly applies to components
which carry high voltage or where the voltage is unknown.
Secure these components using insulating covers. If technical reasons make it
impossible to do this, switch them off or have this action carried out at the site for
the duration of your work after consulting whoever is responsible. Make sure this
is done properly.
