7 OPTIONAL KITS AND ACCESSORIES

7.1 OPTIONAL KITS

The optional kits are hardware resources added to the inverter in the manufacturing process.
Thus, some models cannot receive all the options presented.
Check the optional kits available for each inverter model in

7.1.1 RFI Filter

Inverters with code CFW500...C... are used to reduce the disturbance conducted 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 emission 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 are used in IT networks (neuter not
grounded or grounded through a high ohmic value resistor), always set the
grounding switch of the capacitors of the internal RFI filter to the NC position
(as shown in
damage to the filter capacitors of the inverter.

7.1.2 Protection Rate Nema1

The inverters with code CFW500...N1 are used when protection rate Nema 1 is desired and/or
when metallic conduits are used for the wiring of the inverter.

7.2 ACCESSORIES

The accessories are hardware resources that can be added in the application. Thus, all models
can receive all the options presented.
The accessories are incorporated to the inverters in an easy and quick way by using the
concept "Plug and Play". 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.
