Unpacking
Please check for completeness of parts while unpacking. Also
check for any mechanical damage or loose parts. In case of
transport damage inform the supplier immediately and do not
operate the instrument.
Positioning
Two positions are possible: According to picture 1 the front
feet are used to lift the instrument so its front points slightly
upward. (Appr. 10 degrees)
If the feet are not used (picture 2) the instrument can be
combined with many other HAMEG instruments.
In case several instruments are stacked (picture 3) the feet
rest in the recesses of the instrument below so the instru-
ments 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.

operation without any danger to the operator. According to
safety class 1 requirements all parts of the housing and the
chassis are connected to the safety ground terminal of the
power connector. For safety reasons the instrument must only
be operated from 3 terminal power connectors or via isolation
transformers. In case of doubt the power connector should
be checked according to DIN VDE 0100/610.
Do not disconnect the safety ground either inside
or outside of the instrument!
The line voltage of the instrument must correspond to the
line voltage used.
Opening of the instrument is allowed only to qualified
personnel
Prior to opening the instrument must be disconnected from
the line and all other inputs/outputs.
In any of the following cases the instrument must be taken
out of service and locked away from unauthorized use:
Visible damages
Damage to the power cord
Damage to the fuse holder
Loose parts
No operation
After longterm storage in an inappropriate environment ,
e.g. open air or high humidity.
Excessive transport stress
Exceeding 42 V
By series connecting all outputs the 42 V limit can
be exceeded which means that touching live parts
may incur danger of life! It is assumed that only
qualified and extensively instructed personnel are
allowed to operate this instrument and/or the
loads connected to it.
Proper operating conditions
The instruments are destined for use in dry clean rooms. Ope-
ration in an environment with high dust content, high humidity,
danger of explosion or chemical vapors is prohibited. Opera-
ting temperature is 0 ... +40 degrees C. Storage or transport
limits are –10 ... +70 degrees C. In case of condensation 2
hours are to be allowed for drying prior to operation. For safety
reasons operation is only allowed from 3 terminal connectors
