Note
To prevent the strong power from interfering with the weak power, the strong-power cables must
be separated from the weak-power cables during cabling in the shaft. Grounding cables must be
used to separate strong-power and weak-power traveling cables. "Strong power" refers to the
voltage of 36 V and above.

3.8 Installation of Shaft Position Signals
In elevator control, to implement landing accurately and running safely, car position needs to
be identified based on shaft position signals.
These shaft position signals include the leveling switches, up/down slow-down switches, up/
down limit switches, and up/down final limit switches.
These shaft position signals are directly transmitted by the shaft cables to the MCB of the
controller. For the electrical wiring method, refer to Figure 3-22.
The following figure shows the arrangement of shaft position signals in the shaft.
