7 OPTIONAL KITS AND ACCESSORIES
7.1 OPTIONAL KITS
The optional kits are hardware resources added to the drive in the manufacturing process.
7.1.1 RFI Filter
Built-in RFI filter option is available to reduce the conducted disturbance from the drive to
the main power supply in the high frequency band (>150 kHz). It is necessary to meet the
maximum levels of conducted and radiated emissions of electromagnetic compatibility
standards, such as EN 61800-3 and EN 55011. For further details, refer to
section
3.3 - Installations According to European Directive of Electromagnetic Compatibility
.
ATTENTION!
When drives with internal RFI filter is used in IT networks (neutral conductor
not grounded or grounded through a high ohmic value resistor), remove
grounding screw XE1, since those kinds of network cause damage to
the filter capacitors of the drive.
7.1.2 Disconnecting Switch
An integrated disconnecting switch is available as an option.
7.2 ACCESSORIES
The accessories are hardware resources that can be added to the application.
The accessories are incorporated to the drives in an easy and quick way by using the
“Plug and Play” concept. When an accessory is connected to the drive, the control
circuitry identifies the model and informs the code of the accessory connected in
parameter P0027. The accessory must be installed or modified with the drive de-
energized. They may be ordered separately and are sent in their own package containing
the components and manuals with detailed instructions for their installation, operation
and setting.
