7 OPTION KITS AND ACCESSORIES
This chapter presents:
The option kits that can be integrated to the inverter from the
factory:
- External 24 Vdc power supply for control and keypad.
- Nema 1 Protection degree (Frame size E).
Instructions for the proper use of the option kits.
The accessories that can be integrated to the inverters.
Instructions for the installation, operation, and programming of the accessories are described in their own
manuals and are not present in this chapter.
7.1 OPTION KITS
7.1.1 Nema 1 Protection Degree - Frame Sizes B, C and E
Inverters with the following codification: CFW11...O...N1.
Refer to Item 3.1.5 Installation of the Inverter with Nema1 Kit (Option, CFW11....T...ON1...) on a Wall - Frame
Size E on page 3-11, and Section 8.6 NEMA 1 KITs on page 8-16.
7.1.2 Safety Stop Function
Inverters with the following codification CFW11...O...Y.... Refer to Section 3.3 SAFETY STOP FUNCTION on
page 3-54.
7.1.3 24 Vdc External Control Power Supply
Inverters with the following codification: CFW11...O...W...
The use of this option kit is recommended with communication networks (Profibus, DeviceNet, etc.), since the
control circuit and the network communication interface are kept active (with power supply and responding to
the network communication commands) even in the event of main power supply interruption.
Inverters with this option have a built-in DC/DC converter with a 24 Vdc input that provides adequate outputs
for the control circuit. Therefore, the control circuit power supply will be redundant, i.e., it can be provided
either by a 24 Vdc external power supply (connection as shown in Figure 7.1 on page 7-2) or by the standard
internal switched mode power supply of the inverter.
Observe that the inverters with the external 24 Vdc power supply option use terminals XC1:11 and 13 as the input
for the external power supply and no longer as the output like in the standard inverter Figure 7.1 on page 7-2.
In case of interruption of the external 24 Vdc power supply, the digital inputs/outputs and analog outputs will
no longer be fed, even if the mains power is on. Therefore, it is recommended to keep the 24 Vdc power supply
always connected to the terminals XC1:11 and 13.
