All input and output lines that are not connected to the supply
!
network must be laid out as shielded and twisted cables (do not
run them in the vicinity of power cables or components). The
shielding must be grounded to the earth potential on the instru-
ment side.
Do not connect any additional loads to the supply terminals of
!
the instrument.
The instrument is not suitable for operation in areas with an ex-
!
plosion hazard.
An electrical connection which deviates from the connection di-
!
agram may result in the destruction of the instrument.
If the mains supply is subject to interference (e. g. thyristor con-
!
trols), the instrument should be supplied via a isolating trans-
former.
Supply fluctuations are only permissible within the specified
!
tolerances
