Unused cable glands should be closed off
Feed in the bus cable through the gland 1 The gland is suitable for cable diameters of 6…12 mm (0 24…0 47 in) Observe the
tightness of the cable entry
Make the electrical connection of the input line at the screw terminals 3b, whereby with fieldbus devices no polarity has to be
observed The terminals are suitable for wire cross-sections of 0 3…2 5 mm 2 (22 -14 AWG)
The shield of the bus connection is
• with conductive cable glands (recommended) directly connected with the housing
• with non-conductive cable glands to be placed onto the inner screw terminal 4
NOTE: N When connecting shielded cable, connect the cable shield on both sides (on the positioner as well as on the system
side) For selection of cable, see recommendation for cable types according to IEC 1158-2
For connection to a local ground, use the internal and external ground terminal 4
Test sockets for measuring purposes are integrated into the connecting terminals With version HART or FoxCom at clamps
11+ and 12– a handheld terminal or modem for communication can be attached
