the proper installation and start-up:
1. With the inverter de-energized, remove the front
cover of the Inverter (Figure A1 on page 17).
2. Fit the accessory to be installed as shown in Figure
A1 on page 17.
3. Power up the inverter.
5 CONFIGURATIONS
The CFW100-IOAR connections must be done to the
I/O expansion connector as per Table 1 on page 6.

The location of switch S1 to select the type of analog
input signal can be better viewed in Figure A2 on page
18 and must be configured according to Table 2 on
page 7. In order to use the analog input with signal
in current, switch S1 and related parameters must be set
according to Table 2 on page 7. For further details,
refer to chapter 12 of the CFW100 programming manual.
