Initial Inspection
Immediately after receipt, unpack the KONSTANTER and all
included accessories, and inspect for damage and
completeness.
Unpacking
•
Other than the usual care exercised in handling electronic
equipment, no additional precautions are required when
unpacking the instrument.
•
The KONSTANTER is delivered in recyclable packaging,
which provides for adequate protection during transport as
substantiated by testing. If the instrument is repacked at a
later point in time, the same packaging, or its equivalent, must
be used.
Visual Inspection
•
Compare the order number or type designation included on
the packaging and/or the serial plate with the particulars
shown in the shipping documents.
•
Make sure that all accessory components have been included
(
→
Kap. 1.3, “Options and Accessories”).
•
Inspect the packaging, as well as mechanical instrument and
accessory components for possible transport damage.
Complaints
If damage is discovered, immediately file a claim with the freight
forwarder (save the packaging!). If other defects are detected, or
in the event that service is required, inform your local
representative, or contact us directly at the address included in
the last page of this handbook.

Warnings and Safety Precautions
The KONSTANTER has been manufactured and tested in
accordance with the electrical safety regulations listed in the
technical data as a safety class I device, and has been shipped
from the factory in flawless technical safety condition. In order to
maintain this condition and to assure safe operation, users must
observe all notes and warnings included in these operating
instructions. These are identified with the following headings:
Caution!
A note concerning operation, practical advice or other information which
must be adhered to in order to prevent damage to the KONSTANTER, and
to assure correct operation.
WARNING!
An operating procedure, practical advice or other information which must
be adhered in order to assure safe operation of the KONSTANTER, and to
prevent personal injury.
The most important warnings are summarized below. Reference is made
to these warnings at appropriate points within the operating instructions.
Important Warnings
WARNING I – Protective Grounding
The KONSTANTER may only be placed into operation after the
protective conductor has been connected. Interruption of the
protective conductor, either inside or outside of the
KONSTANTER, or disconnection of the protective conductor
terminal may transform the KONSTANTER
into a source of
potential danger. Intentional interruption is prohibited.
62N: The device is connected to the mains by means of a 3
conductor cable with mains plug. The plug may only be inserted
into a suitable outlet with earthing contact. This safety precaution
must not be defeated though the use of an extension cable
without protective conductor.
64N: These devices are permanently connected to the mains with
a 5-pole terminal block for 3-phase current (5 conductor).
WARNING II – Impaired Safety
If it can be assumed that safe operation is no longer possible, the
KONSTANTER
must be removed from service and secured
against inadvertent use. It must be assumed that safe operation is
no longer possible:
•
If the KONSTANTER
demonstrates visible damage
•
If the KONSTANTER
no longer functions
•
After lengthy periods of storage under conditions which
deviate from specified storage conditions
•
After extraordinary stressing due to transport
WARNING III – Opening Housing Panels
Voltage conducting parts may be exposed when housing panels
are opened, as long as the KONSTANTER
is connected to supply
power.
Any contact with these exposed conductive parts is life
endangering.
For this reason, housing panels may only be opened and/or
removed by trained personnel who are familiar with the dangers
involved.
WARNING IV – Repair by Trained Personnel
Voltage conducting parts may be exposed when housing panels
are opened, as long as the KONSTANTER
is connected to supply
power.
Maintenance and repair work, as well as internal balancing, may
only be performed by trained personnel who are familiar with the
dangers involved.
The KONSTANTER
must be disconnected from all external power
sources before work of this type is performed, in as far as this is
possible. A 5 minute waiting period must be observed after
disconnection in order to allow internal capacitors to discharge to
safe voltage levels.
WARNING V – Fuse Replacement
Only specified fuse types with the specified nominal current rating
may be used to replace blown fuses (see Technical Data and
specifications on the serial plate).
Tampering with fuses or fuse holders is prohibited (“repairing”
fuses, short-circuiting fuse holders etc.).
Significance of Symbols
