Chapter 15 – Installation
Each analog input has three terminals: positive voltage, positive current and negative terminal, which are
used for the current and for the voltage, as shown in Figure 113To define if the driver will measure voltage, it
is necessary to select an internal jumper in the module.
Figure 113: Analog input terminals
In order to configure the analog input to measure voltage signals, remove all connectors and cables which
are connected to the module and remove the back panel of the RA331, RA332, or RA333 removing the 12
screws of the panel and the screw of the protective grounding, as shown in Figure 114.

Remove the board corresponding to the channel to be configured. In order to configure a channel for voltage,
connect the jumper between positions 1 and 2 as shown in Figure 115.
