n-Line System IMx-M
User Manual
The fan tray must be inspected regularly and clean any air intake filters for optimal
performance to ensure proper ventilation.
General Electrical Interface
Important - All wires and cables connected to input and output terminals shall
have a flammability rating VW-1, FT-1 or fulfill the requirements according to IEC
60332-1-2 or IEC 60332-2-2.
Sensor Cables
When routing
a sensor cable, it is important that the cable is firmly fixed. The cable may
never be allowed to vibrate or oscillate, since this effects the capacitance of the cable,
and thereby the measurement result.
The sensor cable may not be routed or bundled together with supply cables since doing
so can generate strong magnetic fields.
To connect the IMx-M rack to sensors, the following cable type is recommended:
•
Shielded, twisted pair 2 x 2 x 0,5 mm2 (FKAR-PG 2 x 2 x 0,50, DUE 4002 or
corresponding)
•
Cable type shall have a flammability rating VW
-1, FT-1 or fulfill the requirements
according to IEC 60332-1-2 or IEC 60332-2-2.
Important - In general, all sensor cables must be routed as far away as
possible from the high voltage cables. If this cannot be done, care should be taken
to use high quality shielded cables.
Supply Cable
To connect an Mx-M rack to 230 V AC or 110 V AC, use the following:
•
FKLK 3 x 1,5 mm2 or EKLK 3 x 1,5 mm2 or corresponding, with minimum voltage
requirement 300 V and minimum temperature -40 ºC.
•
Cable type shall have a flammability rating VW
-1, FT-1 or fulfill the requirements
according to IEC 60332-1-2 or IEC 60332-2-2.
It is required that the IMx-
M rack must be connected to protective ground/earth (PE).
Refer to Mains Power
for attaching power cable to the mains power/power grid.
Important - The cross section area of the PE wire must be equal or greater
than the cross section area of the power wires. The PE wire should be color labeled
green/yellow. However, in some countries, other cable requirements may apply.
