Voltage Interface Module Wiring

Use the following guidelines and refer to the TeSys avatar wiring diagrams to wire the voltage interface module (VIM).

The voltage interface module has one connection point through a single, removable spring terminal connector for the mains voltage measurement input. The connector is positioned on the top of the module.

VIM spring terminal connector

VIM wiring for Three–phase applications

3-Phase, 5-Pin connector pin number	Terminal identification	Signal
1	L1	Phase 1 Voltage
3	L2	Phase 2 Voltage
5	L3	Phase 3 Voltage

VIM wiring for Single-phase applications

1-Phase, 5-Pin connector pin number	Terminal identification	Signal
1	L1	Line or Neutral
3	L2	—
5	L3	Neutral or Line

Remove the spring terminal connector. It is positioned on the top of the module, behind the flat cable connection.
Refer to the table above and make the power connections to the VIM connector. See Accessories Cabling for cable types and sizes.
Insert the spring terminal connector back into the top of the VIM.

NOTE: Voltage frequency detection is on L1. When wiring a line-neutral single-phase system, if the neutral is grounded, ensure that the line is in L1 and the neutral is in L3. Otherwise the frequency reported may be zero.
