Make sure that measurement cables that are used for measuring high
l
dynamic or distorting signals are not closely positioned to measurement
cables used for measuring small sensitive signals.
Keep all measurement cables well separated from cables connected to
l
high switching loads or motor cables.
Separate measurement equipment and cables from potentially interfering
l
equipment like frequency inverters or wireless equipment.
General cabling remark: Only use properly rated cables for the signal to
measure, both voltage and current rating should be matched to the signal to
measure.
WARNING
This instrument must be properly earthed.
When using this card we advise to use the standard GEN series protective earth
connections to ensure the entire unit is earthed.
Please see section "Connecting power" on page 57 for further details.
If connection to a protective earth is not possible for any reason then
please refer to the international safety standard EN 50191:2000
WARNING
Overvoltage and current protection
All signal inputs are protected against voltage overload. This is specified at
± 1000 V for all ranges except for the ± 1000 V range that is limited to
± 1250 V. Exceeding these limits, particularly when connected to potentially
high-current sources, can cause severe damage that is not covered by the
manufacturer's warranty.
WARNING
Disconnect voltages before removing the card from the system.
The measuring circuit can carry hazardous voltages and should be
disconnected before the card is removed from the card slot of the measurement
system.
