OPTION KITS AND ACCESSORIES
This chapter presents:
The option kits that can be incorporated to the inverter from
the factory:
- RFI filter;
- Safety Stop according to EN 954-1 category 3;
- External 24 Vdc power supply for control and keypad.
Instructions for the proper use of the option kits.
The accessories that can be incorporated to the inverters.
Details for the installation, operation, and programming of the accessories are described in their own manuals
and were not included in this chapter.
7.1 OPTION KITS
Some models cannot incorporate all available option kits. Refer to table 8.1 for a detailed description of the
option kits that are available for each inverter model.
The inverter codification is described in chapter 2.
7.1.1 RFI Filter
Inverters with the following codification: CFW11XXXXXXOFA. Refer to table 8.1 for information on availability
of this option kit for each inverter model.
ATTENTION!
Do not use inverters with internal RFI filters in IT networks (ungrounded neutral or grounding provided
by a high ohm value resistor) or in grounded delta networks (“delta corner earth”). These type of
installations will damage the inverter filter capacitors.
The RFI filter reduces the conducted noise of the inverter to the electrical supply system in the high frequency
range (>150 kHz).
The RFI filter is required for the compliance with conducted emissions limits established by the Electromagnetic
Compatibility standards such as EN 61800-3 and EN 55011.
For the proper operation of the RFI filter, please follow the instructions listed in item 3.3 for the installation of
the inverter, motor, cables, etc. This chapter also provides information on the compliance of these standards,
such as the maximum motor cable length.
7.1.2 Safety Stop According to EN 954-1 Category 3 (Pending Certification)
Inverters with the following codification: CFW11XXXXXXOY.
The inverters with this option are equipped with an additional board (SRB) that contains 2 safety relays and an
interconnection cable with the power circuit.
