Fitting the cable
Procedure:
See fig. 2.
1. Connect the red conductor(s) to terminal B
(pos. 1).
2. Connect the green conductor(s) to terminal A
(pos. 2).
3. Connect the cable screens to earth via the earth
clamp (pos. 3).
It is important to connect the screen to
earth through the earth clamp and to
Note
connect the screen to earth in all units
connected to the bus line.
