5.8.1 CONNECTION DIAGRAM OF THE TW INPUTS
The RPV311 provides the capability for connecting one 3-phase circuit (phases A, B, and C):
Connection diagram for TW inputs
3-element (Phases A, B and C) connection : in
this case, the three elements are equivalent to
the values of TW voltage.
5.9 ANALOG CURRENT INPUTS
The RA331, RA332, and RA333 modules have up to 8, 16 or 8 analog inputs, respectively, which can be
configured for measurement of current. All channels are identified of 101 to 108 for the RA331 and RA333,
and 101 to 116 for the RA332.
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 117 . To define if the driver will measure current,
it is necessary to select an internal jumper in the module.
Figure 117: Analog Input Terminals
In order to configure the analog input to measure current 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 118
