SKF Multilog On-Line System IMx-M
User Manual
A condition monitoring module (CMM) and a protection module (PRM) must be
installed as a pair in order to ensure the internal power redundancy.
Due to the physical reason, when mounting a pair of CMM and PRM, must
always mount the PRM before the CMM in order to avoid any damages to the PRM.
However, when dismounting a pair of CMM and PRM, it must be the other way
around. Always dismount the CMM before the PRM. Otherwise, the PRM can be
seriously damaged.
In general, all signal cables must be routed as far away as possible from the
high voltage cables.
It is always recommended to use high quality shielded cables and care must be
taken to ensure that the shield is properly connected to eliminate interference and
noise.
Grounding procedure must be handled with special care to prevent ground
loops:
Be sure to read "
" chapters thoroughly
and understand them.
SKF USB isolator cables must always be used when connecting to IMx-M USB
ports.
Equipment connected to buffered outputs must be isolated from the protective
earth.
Instrument ground (IGND) should be connected and joined to protective
earth/ground at one point only.
In general, it is recommended to connect shield to the ground in only one side
of the sensor/signal cable to avoid potential ground loops.
An IMx-M rack must be connected to protective earth since surge suppressors
are connected between network terminals and protective earth.
Make sure that protective earth and instrument ground (IGND) are properly
connected before connecting any of the input or output terminals of IMx-M rack.
