Installing fieldbus communication on the transmitter
— The PROFIBUS PA transmission technology for intrinsically safe applica-
tions is MBP. MBP stands for:
– Manchester Coding (M)
– Bus Powered (BP)
— 5 transmitters can be connected to a segment with a typical segment cur-
rent of 100 mA.
 Install the 4-wire connection cable in the cable gland, cut it to length and
strip off the insulation (approx. 80 mm).
 Shorten the shield (if installed) to prevent short-circuiting.
 Connect cable:
1 4-pin terminal block for Dräger Polytron 7000, observing the polarity.
2 4-pin terminal block for Dräger Polytron 7000, observing the polarity.
 Slide connecting terminal back into holder.
 Secure cable in holder.
 Fold up the installation notes and place them in the Dräger docking station
for future use during commissioning.
 Refit raincover (protection against dust and splashing water).
Installing the transmitter in 4-wire connection:
CAUTION
With 4-core connection the transmitter has no Ex protection. Once the trans-
mitter has been used after installation in this manner, it may never be
installed in explosion-hazard areas. Explosion hazard!
