Precautions to be taken during the wiring
Two cable entries are available, one of which is closed by a plug. If the open entry is not the desired
one, proceed as follows:
• Remove the plug, install Teflon tape on its thread to ensure the sealing, and screw it
onto the other cable inlet.
• Pass the cable through the open cable inlet and connect it.
4.2 Supply voltage and load resistance
Check that the load resistance is in
the operational zone indicated on the diagram
below.
Note:
In the case of the smart model, a minimum load resistance of 250 ohms is necessary to
communicate with the FXW
• A flameproof plug is essential on the second fitting if the transmitter is
protected against explosion by means of an enclosure.
• If the insulation is verified after wiring, a megohmmeter with a test voltage of
250 VDC maximum should be used. If the device is equipped with a surge
protector, do not perform dielectric testing or insulation resistance testing.
