4.5.3 the better anti-interference measure
The better anti-interference measure is realized through the installation of noise filters on
both side of I/O of elevator drive controller. And the elevator integrated drive controller is shielded
by putting itself into the box.

4.5.4 Relation between wiring length and carrier frequency.
If the wiring between the elevator integrated drive controller and the motor room is too long,
higher harmonic leakage current will be increased due to the influence of wire distributed
capacitors, which might enable over-current protection for the drive controller output and produce
adverse impact on surrounding equipment and the motor. Hence, preferably, the wiring between
the elevator integrated drive controller and the motor room shall not be more than 100m in length.
If the length is over 100M, please adjust the carrier frequency P02.14 by referring to the Table
below and select the appropriate output-side filter and reactor.
