Instruction Manual for AS380 Series Elevator Integrated Drive Controller
Appendix A EMC Installation Guide
When such weak voltage equipment as
control computers, measuring gauges,
radio sets and sensor and their signal
lines are installed in a same control
cabinet with elevator integrated drive
controller and are wired very close to
each other, the radiated interference
may cause malfunction of peripheral.
1. Susceptible peripherals and their signal lines must
be arranged far away from elevator integrated drive
controller. Furthermore, the signal line shall be of type
shielded line which shielding layer is properly
grounded. Signal line shall be threaded into metal hose
and arranged far away from the input/output cable of
elevator integrated drive controller. These two kinds of
cable shall be perpendicular to each other.
2. radio noise filter and linear noise filter (ferrite
common mode choke) as installed at both input side and
output side of elevator integrated drive controller will be
effective for suppress its noise radiation;
3. the cables of elevator integrated drive controller
shall be arranged in thicker shielding layer such as ducts
with thickness 2mm or be embedded in cement tray. In
addition, the cables must be threaded in grounded metal
hose. (Four-core cable may be appreciable for motor
cable. One end of a core conductor shall be grounded to
the elevator integrated drive controller side and another
end shall be connected to motor casing.
A2 Requirements on Cable Laying
A2.1 Requirement on Cable Laying
As shown by figure A2.1(a): To prevent mutual coupling of interferences, control signal cable
must be laid separately with supply cable and motor cable and be spaced as far as practicable. as
shown by figure A2.1(b): where the control signal cable has to cross over supply cable or motor
cable, they must be perpendicular with each.
