I Initial Inspection
Immediately after receipt, unpack the KONSTANTER and all
included accessories, and inspect for damage and completeness.
Unpacking
Great care must be exercised when removing the electronic
device from the package.
Pull the KONSTANTER from its package.
In doing so, do not grasp rotary knobs, terminals or jacks in
order to avoid damage.
Do not allow the KONSTANTER to fall out of the packaging.
Controls, displays, terminals and internal components might
otherwise be damaged.
Do not, under any circumstances, touch the KONSTANTER’s
electrical terminals before grounding yourself to the housing
in order to neutralize potential differences. Sensitive
electronic circuitry might otherwise be damaged as a result
of electrostatic discharge.
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
(see chapter 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.
II Warnings and Safety Precautions
The KONSTANTER has been manufactured and tested in
accordance with the electrical safety regulations listed under
“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:
ATTENTION!
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 it into a source of danger. Intentional
interruption is prohibited.
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.
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
voltage sources before work of this type is performed, in as far as
this is possible. A five 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.).
