Instructions for EMC-correct installation

EMC (Electrom agnetic C ompatibility) involves the noise emission and noise immunity of electrical equipment.
Optional radio interference suppression filters are available to limit the noise emission.

Fig. 3.3 Location of the components
The radio interference suppression filter and drive converter must be
connected through a large surface area. The most favorable method is to
mount all of the components on a bare metal mounting panel (e.g.
galvanized steel). A line reactor must be connected between the radio
interference suppression filter and the drive converter.
The cabling should be kept as short as possible. The line feeder cable to
the radio interference suppression filter should be routed separately away
from other cables.
The motor must be connected using a screened cable, e.g. Siemens
PROTOFLEX-EMV-CY (cross-section up to 120 mm
PROTODUR NYCW (cross-section > 120 mm
connected to the motor- and drive converter housing through the largest
possible surface area to keep inductances as low as possible.
Use screened control cables to increase the noise immunity. Connect the
screens of the control cables to the mounting positions provided. Screen
clamps are provided with every SIMOVERT MASTER DRIVES to connect
the screens of the control cables (+ Fig. 3.4.1). Otherwise, cable ties can
be used to connect the screen (+ Fig. 3.4.2).
♦ Do not interrupt the screens, e.g. when installing intermediate
terminals.
♦ Control cables and power cables (= line feeder cable, motor cable)
must be routed separately away from one another.

instructions for EMC correct design of drives"
