7 OPTIONAL KITS AND ACCESSORIES

7.1 OPTIONAL KITS

The optional kits are hardware resources added to the inverter in the manufacturing process.

7.1.1 RFI Filter

Built-in RFI filter option is available to reduce the conducted disturbance from the inverter 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
TO EUROPEAN DIRECTIVE OF ELECTROMAGNETIC COMPATIBILITY on page
ATTENTION!
When inverters 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 inverter.

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 inverters in an easy and quick way by using the "Plug
and Play" concept. When an accessory is connected to the inverter, 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 inverter 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.
