gland fittings and nut from the outside of the enclo-

INSTALLATION AND WIRING
3.2 Wiring Directly To A Profibus Network
To connect a Profibus-configured Model 1056 to a Profibus network, the conventional method is to wire a stan-
dard purple Profibus cable directly to the Profibus board inside the instrument. The Profibus board is designed
to accommodate direct wiring of a Profibus cable to a removable 4-lead terminal block on the Profibus board.
1. Feed the purple Profibus cable through a cable gland fitting. Install the cable gland fitting into the enclosure
opening on the leftmost side of the enclosure nearest the front of the door hinge. See photo. Note that the
power cable should be installed in the leftmost side of the enclosure farthest from the front of the door hinge
– as shown in the photo below.
