rection of rotation of the motor is set in such a way that it only runs in the direction
of the distance to be traversed. Immediately after reaching one of the two end posi-
tions, the motor must be switched off.
End positions of the vacuum circuit-breaker on the withdrawable part:
• completely retracted in the mating contacts (in operating position), or
• fully extended (in service position).
The control signals for this are provided by the position buttons S8 for the “service
position” end position and S9 for the “operating position” end position. The position
buttons are not designed to switch the motor power and are only used for signalling.
A switching element suitable for switching the motor must be able to safely switch
off the following secondary voltage of utilisation category DC-3 and DC-5:
Utilisation category DC-3
and DC-5
DC 220 V: 1.5 A
DC 110 V: 2.5 A
For this purpose, the following signals of the vacuum circuit-breaker must be used
and processed accordingly in the electronic circuit by the customer:

Manual movement of the motor-driven withdrawable part using the hand
crank 3AX1430-8A
Notes on using the hand
crank for the motor-
driven withdrawable part
As long as secondary voltage is applied, the motor-driven withdrawable part must
not be moved manually with the hand crank.
Risk of injury due to inserted hand crank on the withdrawable part
As long as secondary voltage is applied, the motor of the withdrawable part can be
started at any time.
If the hand crank is inserted into the coupling of the withdrawable part, the sudden
turning or detachment of the hand crank can lead to considerable personal injury or
damage to property.
• Do not insert the hand crank into the coupling of the withdrawable part as long
as secondary voltage is applied.
• After manual operation without secondary voltage, immediately remove the
hand crank from the withdrawable part
In the event of a failure of the secondary voltage or during maintenance work, the
motor-driven withdrawable part can be moved manually with the hand crank
