1.2 Unpacking
While unpacking, check the package contents for com-
pleteness (measuring instrument, power cable, possibly
optional accessories). After unpacking, check the instru-
ment for mechanical damage occurred during transport
and for loose parts inside. In case of transport damage,
please inform the supplier immediately. The instrument
must not be operated in this case.
1.3 Positioning
Two positions are possible: According to Fig. 1 the front
feet are folded down and are used to lift the instrument so
its front points slightly upward (approx. 10 degrees). If the
feet are not used (Fig. 2) the instrument can be stacked
safely with many other instruments. In case several
instruments are stacked (Fig. 3) the feet rest in the
recesses of the instrument below so the instruments can
not be inadvertently moved..
Please do not stack more than 3 instruments. A higher
stack will become unstable, also heat dissipation may be
impaired

1.4 Transport and Storage
Please keep the original packaging for possible shipping at
a later point. Damage during transport due to inappropriate
packaging is excluded from the warranty. The instrument
must be stored in dry, closed indoor premises. If the in-
strument was transported under extreme temperatures, it
is advisable to allow a minimum of two hours to reach the
appropriate temperature before operating the instrument.
1.5 Safety Instructions
This instrument was built in compliance with VDE0411 part
1, safety regulations for electrical measuring instruments,
control units and laboratory equipment. It has been tested
and shipped from the plant in safe condition. It is in
compliance with the regulations of the European standard
EN 61010-1 and the international standard IEC 61010-1. To
maintain this condition and to ensure safe operation, the
user must observe all instructions and warnings given in
this operating manual. According to the regulations of
protection class 1, all casing and chassis parts are
connected to the protective earth conductor during
operation.
If uncertainty exists about the function or safety of the
power sockets, the outlets must be examined in accor-
dance with DIN VDE 0100, part 610.
❙
The available mains voltage must correspond to the
values specified on the instrument label.
❙
The instrument may only be opened by fully trained
personnel.
❙
Prior to opening, the instrument must be turned off and
isolated from all circuits.
In the following cases, remove the instrument from opera-
tion and secure it against unintentional operation:
❙
Visible damage to the instrument
❙
Cable damage
❙
Fuse holder damage
❙
Loose parts in the instrument
❙
The instrument is no longer working
❙
After an extended period of storage under unfavorable
conditions (e.g. outdoors or in damp rooms)
❙
Rough handling during shipment.
Prior to switching on the product, it must be ensured that
the nominal voltage setting on the product matches the
nominal voltage of the AC supply network. If it is neces-
sary to set a different voltage, the power fuse of the prod-
It is prohibited to disconnect the earthed protective
connection inside or outside the instrument!
Exceeding the Low Voltage Protection!
For the series connection of all output voltages, it is pos-
sible to exceed the low voltage protection of 42 V. Please
note that in this case any contact with live components
is life-threatening. It is assumed that only qualified and
trained personnel service the power supplies and the
connected loads.
