4.7 Electrical connections
The ND9200F is powered by FOUNDATION Fieldbus
(IEC 61158-2). The same bus cable is used also for the
fieldbus communication.
The bus cable is led through a M20 x 1.5 (E1)/1/2 NPT
(E2) cable gland. Connect the conductors to the termi-
nal strip as shown in Fig. 7.
Reverse polarity protection permits connection of the
bus cables in any order.
The cable shield can be grounded by connecting the
shield to the earth connection screw. The shield can be
left unconnected by using the empty terminal.
Please note following before mounting the cover of
the valve controller:
❑
Attach the LUI (223) cabling to the sticker on the
reverse side of the LUI.
Check that the cabling does not get squeezed by
the electronics cover (39) or the device cover
(100).
❑
Check using a feeler gauge that the clearance
between the position indicator (109) and the
electronics cover is 1 mm.
