I/O Expansion Modules
1. With the inverter powered down, remove its front
cover (Figure A1 on page
2. Fit the accessory to be installed as shown in
A1 on page
3. Power up the inverter.

5 CONFIGURATIONS

The location of switch S1.1 to select the type of signal
at the analog input can be better viewed in
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
Switch S1.2, presented in
used to select the type of analog output. For a voltage
output you must set S1.2 = ON and related parameters,
for current output the switch is set S1.2 = OFF, as
presented in
refer to chapter 12 of the CFW100 programming manual.
