Operating conditions
The ambient temperature range during operation
should be b5 °C and +40 °C and should
not exceed –20 °C or +70 °C during transport or
storage. The operational position is optional, ho-
wever, the ventilation holes on the HM8001-2 and
on the plug-in modules must not be obstructed.
Warranty and Repair
Our instruments are subject to strict quality con-
trols. Prior to leaving the manufacturing site, each
instrument undergoes a 10-hour burn-in test. This
is followed by extensive functional quality testing
to examine all operating modes and to guarantee
compliancewiththespecifiedtechnicaldata.The
testing is performed with testing equipment that
is calibrated to national standards. The statutory
warranty provisions shall be governed by the laws
of the country in which the product was purchased.
In case of any complaints, please contact your
supplier.
Any adjustments, replacements of parts, main-
tenance and repair may be carried out only by
authorized technical personnel. Only original
parts may be used for replacing parts relevant to
safety (e.g. power switches, power transformers,
fuses). A safety test must always be performed
after parts relevant to safety have been replaced
(visual inspection, PE conductor test, insulation
resistance measurement, leakage current mea-
surement, functional test). This helps ensure the
continued safety of the product.
Maintenance
The most important characteristics of the instru-
ments should be periodically checked according to
the instructions provided in the sections “Opera-
tional check and “Alignment procedcure. To obtain
the normal operating temperature, the mainframe
with inserted module should be turned on at least
The
product may only be opened by
authorized and qualified personnel.
Prior to working on the product or
before the product is opened, it must
be disconnected from the AC supply
network. Otherwise, personnel will
be exposed to the risk of an electric
shock.

ensure that ventilation is not impaired in any way.
Instruments with the highest power consumption
should preferably be stacked uppermost.
Safety
This instrument has been designed and tested in
accor dance with IEC Publication 1010-1, Safety
require ments for electrical equipment for mea-
surement, control, and laboratory use. It corres-
ponds as well to the the CENELEC regulations EN
61010-1. All case and chassis parts are connected
to the safety earth conductor. Corresponding to
Safety Class 1 regulations (three-conductor AC
power cable). Without an isolating transformer,
the instrument's power cable must be plugged into
an approved three-contact electrical outlet, which
meets International Electrotechnical Commission
(IEC) safety standards.
Warning!
Any interruption of the protective con-
ductor inside or outside the instrument
or discon nection of the protective earth
terminal is likely to render the instru-
ment dangerous. Intentional interruption
is prohibited.
The istrument must be disconnected and secured
against unintentional operation if there is any
suggestion that safe operation is not possible.
This may occur:
– if the instrument shows visible damage,
– if the instrument has loose parts.
– if the instrument does not function,
– after long storage under unfavourable
circumstances (e.g. outdoors or in moist
environments),
– after excessive transportation stress (e.g. in
poor packaging).
When removing or replacing the metal
case, the instrument must be completely
disconnected from the mains supply.
If any measurement or calibration procedures are
necessary on the opened-up instrument, these
