Description
2.2 Measuring inputs
Voltage measurement
NOTICE
AC voltage measurement only.
The device is not suitable for measuring DC voltage.
PAC3200T is designed for:
● Direct measurement on the system or using voltage transformers. External voltage
transformers are required to measure higher voltages than the permissible rated input
voltages.
● Measurement voltage up to 277 V / 480 V. The device is designed for measuring input
voltages up to 277 V to the neutral conductor and for measuring input voltages up to
480 V to the external conductor.
Connection types
Five connection types have been provided. The device can measure in single-phase, two-
phase, or three-phase mode and can be used in three- or four-wire TN, TT and IT networks.

The input circuit of the device must correspond to one of the connection types listed. Select
the suitable connection type for the purpose.
You can find connection examples in the chapter Connection (Page 23).
NOTICE
The wrong system connection can damage the device.
Before connecting the PAC3200T, ensure that the local power supply conditions match the
specifications on the type plate.
The short code of the connection type must be entered in the device settings at startup. You
can find the instructions for parameterizing the connection type in the chapter
Commissioning (Page 41).
