TERMS AND CONDITIONS OF WARRANTY
Megger will accept a warranty claim brought forward by a customer for a
product sold by Megger under the terms stated below.
Megger guarantees that at the time of delivery Megger products are free
from faults in material and workmanship which would reduce their value and
serviceability to a large degree. This warranty does not cover any error in
the software supplied. During the warranty period Megger will repair faulty
parts or replace them with new parts or parts as new (with the same
usability and life as new parts) at their discretion.
Further warranty claims, in particular those from consequential damage,
cannot be accepted. Each component and product replaced in accordance
with this warranty becomes the property of Megger.
All warranty claims versus Megger expire after a period of 12 months from
the date of delivery. Each component supplied by Megger in the context of
warranty will also be covered by this warranty for the remaining period of
time, but at least for 90 days.
Each measure to remedy a warranty claim must be carried out exclusively
by Megger or one of their authorised service stations.
It is a precondition for accepting a warranty claim that the customer com-
plains about the fault, in a case of an immediately detectable fault within 10
days from the date of delivery.
This warranty does not cover any fault or damage caused by exposing a
product to conditions which are not in accordance with this specification, by
storing, transporting or using it improperly, or having it serviced or in-stalled
by a workshop not authorised by Megger. No claim will be ac-cepted in case
of wear and tear, will of God, or connection to foreign components.
For any damage resulting from a violation of their duty to repair or re-supply
items, Megger can be made liable only in case of severe negligence or
intention. Any liability for slight negligence is disclaimed.

SAFETY INSTRUCTIONS

1. SAFETY INSTRUCTIONS
All persons involved in the installation, operation, maintenance
and repair of this system must have read this user manual
carefully.
The instrument and all additional equipment are in accordance
with the current state of safety technology at the time of
delivery. Owing to the work processes involved, however, there
may be parts of the instrument and its peripherals which
cannot be given optimum protection without an unreasonable
reduction in function and usability. Good personal safety
practice is therefore indispensable in terms of the protection of
staff and the instrument.
The following safety instructions must be complied with.
General instructions
Work on this instrument and its peripherals must only be
performed by qualified and/or trained staff. Other persons must
be kept away.
This user manual must be available for the supervisory,
operating and maintenance staff to refer to.
Improper use may endanger life and limb, the system and
connected equipment, as well as the efficient functioning of the
system (accident prevention regulations). The instrument may
only be used for the purpose for which it is intended by the
manufacturer.
Always use correct tools in perfect condition for all work.
Regular checks must be made to ensure that the relevant
safety regulations are being complied with during operation
and maintenance.

man_t99-1_en_01-5.doc14
The instrument may only be operated by authorised persons
with the appropriate skills.
Only operate the system if it is in technically perfect condition.
No non-original parts may be used for the instrument and its
peripherals, as the necessary safety will not otherwise be
guaranteed. No mode of working which detracts from the
safety of the instrument must be used.
The user is under an obligation to report any changes in the
system to the supervisor responsible without delay.
The user is under an obligation to shut down the instrument
immediately in the event of an instrument malfunction which
detracts from the safety of staff. The instrument may only be
put back into operation once the malfunction has been
rectified.
Electrotechnical instructions
The instrument and all additional equipment must be
connected properly. The relevant EN, DIN and VDE
regulations must be complied with.
Repair and maintenance work must only be carried out when
the system is switched off (dead) and then only by a skilled
electrician in accordance with current accident prevention
regulations (APR). A skilled electrician in the sense of the
accident prevention regulations is a person who can assess
the work assigned to him/her and recognise possible dangers
on the basis of his/her technical training, knowledge and
experience, and of his/her knowledge of the relevant regu-
lations.

1.1. General rules for working with high voltages
Working with high-voltage devices and systems demands
special care.
This is particularly true of mobile operation, i.e. if the
accommodation in question and its equipment do not ensure
safety with permanent safety devices from the outset.
Regulation DIN VDE 0104 "Installation and operation of
electrical test systems" must be complied with to the letter.
This clearly instructs:
- that high-voltage installations must only be operated in
properly secured rooms or behind corresponding barriers,
and safety devices must not be circumvented or put out of
operation.
- that at least two persons must be present during operation,
with one person being able to activate the emergency-off
circuit in the event of an emergency.

man_t99-1_en_01-5.doc16
1.1.1. Supplementary instructions
The following supplementary instructions are not taken directly
from the regulations.
- To avoid dangerous charges, all metal parts in the vicinity
of a high-voltage system must be grounded. Special care is
required in the case of mobile operation in this respect.
- Do not disconnect while live (risk of arcs).
- High-voltage test and burn equipment is short-circuit proof.
This means that there is a danger that the voltage will run
up when a short circuit is removed.
- Connect a discharger parallel to the measuring equipment
in the case of short-circuit current measurements (e.g. 90 V
corona discharger).
- Only ever touch component parts which have been live and
read measuring/test devices if they are visibly grounded
and short-circuited, even if they have been switched off and
discharged properly.
1.1.2. Danger of recurring voltage from space charges
- Only remove grounding and short-circuit when the test
object is to be put into operation again.
- Cables which are not in operation are capacitors.
Ground and short-circuit as a matter of principle.

1.2. Indications used in the description
Important instructions concerning personal protection, work
safety and technical safety are indicated as follows:
WARNING: Warning indicates work and operating
procedures which must be complied with in
full to exclude the possibility of persons
being put at risk. This includes instructions
concerning particular dangers when
handling the instrument.
ATTENTION: Attention indicates work and operating
procedures which must be complied with in
full to prevent the instrument/peripherals
from being damaged or destroyed.
N.B.: N.B. indicates special technical
requirements to which the user must pay
particular attention when using the
instrument.
