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 com-
bined 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.

peratures 2 h should held off on turning the instrument on.

Safety instructions

The instrument conforms to VDE 0411/1 safety standards
applicable to measuring instruments and left the factory in
proper condition according to this standard. Hence it conforms
also to the European standard EN 61010-1 resp. to the inter-
national standard IEC 61010-1. Please observe all warnings
in this manual in order to preserve safety and guarantee
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 qualifi ed
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
qualifi ed 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. Operating
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
