If you continue scrolling the list repeats with a “4” appearing in the
line above the parameter indicator to designate a 4 to 20 mA output.
Analog Output Connections
Connections to all analog outputs (1 to 6, depending on the option)
are made via a 9-pin D-sub connector. The female socket is on the
rear panel. A matching male connector with a patch cable is used for
external connections. Pin assignments are as follows:

Output Pin Output Pin
Output 1 Pin 1 Output 2 Pin 2
Output 3 Pin 3 Output 4 Pin 4
Output 5 Pin 5 Output 6 Pin 6
Output GND Pins 7, 8, 9
Scaling of Measured Parameters
Analog outputs selected as voltages (‘V’ or ‘n’) provide a linear
measurement range centered around the nominal value of the
line-to-line (V
nominal
) or line-to-neutral 3 V

respectively. This diagram depicts the scaling of line-to-line voltage.
