How to make the connection for voltage measurement on a circuit breaker equipped with PTE option?

The connection to the VN, V1, V2 and V3 terminals is made using the 4 strands twisted cord delivered (47090 reference number for identification).
The cable's characteristics are:
- 4 strands twisted cord, not shielded
- Gauge AWG20
- operating voltage 690V max
- maximum current 250mA
- operating and storage temperature: -35
°C..+85°C
- color of insulator: 4 different colors for easy identification
- length of cord 3080mm

The correspondence of the 4 wires to the 4 terminals is not determined. It can be the installer's choice. The reason is that the 4 wires have identical technical parameters. The different coloring of the insulator assures easy identification of each connection.
