4.2.2 Switch cable earthing on/off
In the operating position, the cable is connected to the
main busbar of the unit; the switch is ON and the change-
over switch is in the busbar position.
Initial position:
In the neutral position (see Figure 4-5):

the switch is OFF, see switch (4) position indicator;

the change-over switch is in earthed position, see
position indicator of change-over switch (9);

selector (7) is in the central position.

Procedure for switching cable earthing on
1. Check the position indication to verify that the change-
over switch is in the earthed position. An additional
option is available to inspect the position of the
change-over switch through windows (14) at the front ,
see Figure 4-5. Check the position of all three phases:
use a torch to provide additional light through an
adjacent window;
check the position of the change-over switch;
Figure 4-7 shows the change-over switch in the
earthed position;
Figure 4-8 shows the busbar position;
repeat this procedure for the other two phases.
2. If the panel is not in neutral position, put it in this
position now, see section 4.2.1.
3. Turn the selector anti-clockwise, the control point of
the switch (5) is revealed.
4. Use the built-in voltage detector to check that the
cable is dead.
Arrows and dots visible:
Detector is functioning correctly and the cable
is live;
Arrows and dots not visible: cable is dead.

OTE
The visible dot shows that the detector is
functioning correctly in accordance with the
demands for voltage detecting systems as
described in VDE 0682 art. 415.
This is a continuous internal function check.
