Pay attention to the current direction during wiring. P1 and S1 are dotted terminals, so does P2 and
S2, namely the main circuit cable goes in from P1 and out from P2, and the S1 on output side of R/A
phase must be connected to la, and S2 to lc. The S1 on output side of S/B phase must be connected
to lb, and S2 to lc.
Note:
1. Open circuit is not allowed on output side;
2. Avoid large power and interference during transformer wiring;
3. Wiring of the transformer and terminal expansion board can be carried out only after power off.
C.3 Parameter setup of current transformer of the fan
1. You can select the transformation ratio of the current transformer as needed. Transformation ratio
of 200 or 1000 is recommended.
2. After confirming transformer model, input the rated current value of the cooling fan.
