Installation

2.2 Mounting and attaching the bus cable(s)

3. Shorten the braided shield and foil shield to a length of approximately 12 mm (the foil shield

can be left somewhat longer) and shorten the two fillers to a length of approximately 12 mm.

4. Fold back the braid shield over the cable jacket.

5. Strip approximately 10 mm from the end of the wires.

6. Fit the bus cable to the terminal so that the braided shield is lying directly under the cable

clamp.

7. Screw the ends of the wires to the appropriate terminals (if the cores are stranded, for

example, the trailing cable, 0.25 mm

used).

8. If the bus terminal is at the start or end of a segment, the integrated terminator must be

activated (switch set to Termination on).

Note

The shield clamps are used solely to contact the shields and are not suitable as strainrelief

clamps. This means that the bus cables must be secured as close as possible to the 12M bus

terminals to provide mechanical strain relief.

Note

If the terminating resistor is activated (permitted only at the segment ends), the terminal pair

A1, B1 must be used (A2, B2 are disconnected from the segment).

During operation of the bus terminal in the segment, it requires 5 V to be supplied by the DTE.

The DTE must therefore be turned on and the D-sub male connector inserted and secured by

screws! Due to the necessary termination at the start and end of the segment, the DTE

connected there must not be turned off.

Note

The same wires (green or red) must always be connected to the same terminal A or B in all bus

terminals (and with all bus connectors) and be uniform throughout the segment.
