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).
