3.2.2 Connecting the PROFIBUS cable
The MIQ/(A-)PR component can be connected at the PROFIBUS end
(A) or with a loop-through (B).

PROFIBUS cable
1 Carefully strip the PROFIBUS cable insulation for approx. 20
mm.
2 Bare the PROFIBUS wires from the shielding braid and strip
them for approx. 5 mm.
3 Twist the shielding braid and cover it with approx. 15 mm
insulating tube.
4 Feed the PROFIBUS cable through the cable gland into the
module housing of the MIQ/(A-)PR.
5 Additionally insulate the transition between cable sheath and
insulating tube of the shielding braid (e.g. with insulating tape
or shrinkable tubing), so that no shielding braid is uncovered.
6 Connect the PROFIBUS wires and shield to the terminal
connections of the PROFIBUS module (connections ALine,
BLine and Shield, see section 3.2.1).
