4.2 Manual switching
4.2.1 Switching operating position on/off
In the operating position the cable is connected to the main
busbar of the unit. Here, the switch (5) is ON and the
change-over switch (8) is in the busbar position.
Initial position:
In the neutral position (see Figure 4-2):
the switch is OFF, see switch (4) position indicator;
the change-over switch is in earthed position, see
change-over switch (9) position indicator;
The selector (7) is in the central position.
This initial position has been selected to ensure that all
switching operations are described. If the change-over
switch is already in the busbar position, for instance during
switching on, switching with this change-over switch is
omitted.
Procedure for switching on the operating position
1. Turn the selector (7) clockwise until the control point of
the change-over switch (8) is revealed.
2. Place the operating handle with the arrow pointing
down in the control point of the change-over switch
(8). Switch the change-over switch to the busbar
position by turning the handle anti-clockwise as far as
it will go, i.e. to approximately 190
0
. Additional
resistance will be noticeable towards the end of this
rotation. The handle cannot be removed until busbar
position of the change-over switch has been reached.
