Electrical Connection
Cabling
Use shielded two-core instrumentation cable for the current output of the FMU 130, 131,
230 and 231. For optimal protection against electromagnetic interference, the shield
should be grounded in the control room or the nearest earthing point. A good connection
to ground is essential to good shielding.
Under certain circumstances, the digital communication signal may be affected if
unshielded cable is used.
