CONTROLLER POSITION
AND ELECTROMAGNETIC COMPATIBILITY (1/4)
When the machine room supports or is near a radio or television reception
aerial, do not put the controller cabinet in the aerial receiving zone (figure 1).
If you can not find a suitable place for the frequency drive cabinet, get the aerial
moved! If that is not possible, contact
AUTINOR
who will decide along with the building
owner, what measures need to be taken according to the EN 12015 and EN 12016
Standard for lifts, escalators and passengers conveyors.
PRÉCAUTIONS TO TAKE.
1. The power supply arrival L1, L2, L3 and Earth (Yellow/Green) must all pass through
the same cable.

2. The power link between the MB32 Vector drive and the motor (11, 12, 13 + Earth) must
go through the same cable. In order to reduce disturbances a screened cable (LIYYCY
type, minimal length of cable: 3m50) must be used, even if the motor cable is
mechanically protected by a tube or metal trunking. This screening should consist of at
least one flat cable, the greater the number of flat cables the greater the efficiency of the
screening. The cable should be supple for ease of installation in the machine room and
should comply with EN 81 standards.
To be completely efficient the screening must be connected at the same time to the
controller metal casing and to the motor metal housing.
In order to reduce any coupling effects, it is advisable to maximise the distance between
the motor cable and the three phase power supply cable, both inside and outside the
controller; for the same reason, you should keep the cables carrying high current as far
apart from those carrying low current as possible. These two types of cable should not be
placed in the same trunking, nor go through the controller casing via the same hole.
