1. With the inverter powered down, remove its front
cover ( Figure A1 on page 14 ).
2. Fit the accessory to be installed as shown in Figure
A1 on page 14 .
3. Power up the inverter.
5 CONFIGURATIONS
The CFW100-IOA connections must be done to the I/O
expansion connector according to
Table 1 on page 6 .
The pins of the accessory connector are presented in
Figure A2 on page 15 .

The location of switch S1.1 to select the type of signal
at the analog input can be better viewed in
Figure A2
on page 15 . To use the analog input with voltage
signal, you must set switch S1.1 = OFF and related
parameters, for current input you set S1.1 = ON, as per
Table 2 on page 7 .
