for
AS380 Series Elevator Integrated Drive Controller
42
Wire size: ≥0.75mm2
◇ Communication line and power line must be wired respectively
◇ Grounding of Elevator Shaft Cable and Trailing Cable
During wiring of shaft cable and trailing cable, please note to appropriately divide the strong
current line (includes door machine power supply, safety circuit, door lock circuit and illumination
circuit, etc.) and weak current line (includes communication cable, DC 0V, DC 24V, leveling dry
reed , terminal forced slowdown switch and terminal limit switch, etc.). The communication line
must be twisted pair with strand pitch between 20 and 30 mm. it is strongly recommended to use
shielded twisted pair with grounding protection.
Note: if strong current lines and weak current lines are arranged in parallel, mostly common in
trailing cables, the strong current lines shall be arranged on one side and the weak current line on
the other side. In addition, the strong current lines and weak current lines must be separated with
grounding line.
Note: The wiring rules mentioned above must be shown on design drawings, where the specific
purpose of each wire size must also be defined.
Note: whether it is shielded or not, twisted pair must be used.
4.3.2 Method of Wiring Between Call board and TXV+、TXV-、TXA+、TXA-
◇ Branch Bus
Branches and bus shall be soundly wired in order to avoid excess voltage drop.
It is recommended to use the wiring methods shown by the following Figure 4.3:
Figure 4.3 Wiring between Branch and Bus
◇ The Relation between TXV+、TXV-、TXA+、TXA- and Trailing Cable
TXV+、TXV-、TXA+、TXA- and other weak current signal cables (voltage not more than
24V) are allowed to share a same trailing cable. Other strong current signal cables (voltage
higher than 24V) shall be arranged at the other trailing cable.
