General notes
•
Maximum cable length 50 m
•
Minimum bending radius 120 mm (fixed installation)
•
The cable must not be compressed
•
Protect the cable ends against ingress of moisture
•
When lengthening the cable, ensure pressure equilibration
•
When lengthening the cable, take the length-dependent inductances and capacitances into account
•
Route the signal cables separately from cables with voltages > 60 V
•
Use a screened twisted-pair cable
•
Avoid the vicinity of large electrical installations
NOTE!
In particular, equipment used in potentially explosive areas where hybrid mixtures are present must be
checked. Hybrid mixtures are explosive mixtures of flammable gases, vapors, or mists with flammable
dusts. The operator is responsible for checking that the equipment is suitable for such uses.
