6.3.1.3.- Three-phase connection diagram (4 wires)

6.3.2.- VERIFICATION OF CONNECTIONS

The analyzer will start the connection verification process after power it. This process is

carried out by the unit continuously, regardless of whether it is recording data or not.

We must highlight that the analyzer will indicate faulty connections with the L1, L2 or L3

LED and the indication is realized by the lighted LED (correct connection) or blinking

(incorrect connection).

6.3.2.1.-

The analyzer indicates a faulty connection for voltage sequence error blinking the L1, L2

or L3 LED.

Faulty connection

The figure shows an example of how the CIR-eQ unit indicates the faulty connection of

voltages in phases L2 and L3. In this case, exchange the voltage connections, i.e., L2

and L3.
