Bonding Multiple Sub Panels
Bonding multiple sub panels creates a common low impedance exit path for the high frequency
energy inside the cabinet. Sub panels that are not bonded together may not share a common
low impedance path. This difference in impedance may affect networks and other devices that
span multiple panels. Refer to the illustration below for recommended bonding practices.
Regulatory Requirements
This section has presented guidelines that can minimize noise problems. However, equipment
EMC performance must meet regulatory requirements in various parts of the world, specifically
the European Union. Ultimately, it is the responsibility of the machine builder to ensure that
the machine meets the appropriate requirements as stated.
IQ 2000 Installation for European Directive Compliance
This section specifies installation requirements for compliance to the Low Voltage Directive
(LVD) and the Electromagnetic Compatibility (EMC) Directive for the IQ 2000 drive. The infor-
mation below is based on successful testing using the specified installation methods.
Electromagnetic Compatibility Directive
Although it is impossible to guarantee a specific installation will meet the EMC requirements
without testing, drives installed as described below should be compliant with European EMC
requirements.
Important points are:
◆ Cable shields must be bonded to the enclosure at all entry points in one of two ways. A mat-
ing bulkhead connector can be mounted on the enclosure, or the cable jacket may be
removed so that the shield can be clamped to the enclosure. The motor power cable shield
may be terminated to the drive chassis on those drives that have the motor power cable
bracket supplied with them. In this case the motor power cable shield does not have to be
terminated to the enclosure.
