3.3.4 Inserting the cable in the housing
In order to provide for sufficient EMI/RFI shielding of the positioner to meet the require-
ments regarding electromagnetic compatibility (EMC),
all
electrical wires must be
entered through a ferrite tube in the connection compartment. Proceed as described in
the example below:
1. Remove the cable sheath at the cable end. Cut the (green/yellow) protective ground
conductor (1) and the two 4...20 mA signal lines (2) to the specified length and
remove approx. 6 mm of the insulation.
2. Put the protective hose (4) on the ferrite tube (3).
3. Insert all wires through the cable gland (6) and the ferrite tube (3). Make sure that
the end of the cable sheath (5) protrudes into the connection compartment. Fasten
the cable gland.
4. Fasten the protective ground conductor (1) with the grounding screw and connect
the 4...20 mA signal lines (2) to the signal terminals +(11)/-(12) (see Fig. 18 on page
23 and chapter 3.3.5).
