(
When a ground fault interrupter is used select the one with no influ-
ence for high frequency, and setting current should be 200 mA or
over and operating time, 0.1 sec or over to prevent malfunction.

Wiring
Main Circuit Input/Output
1, 2, 3... 1. Phase rotation of input terminals L1 (R), L2 (S), L3 (T) is avail-
able in either direction, clockwise and counterclockwise.
2. When inverter output terminals T1 (U), T2 (V), and T3 (W) are
connected to motor terminals T1 (U), T2 (V), and T3 (W), re-
spectively, motor rotates counterclockwise, viewed from oppo-
site drive end, upon forward operation command. To reverse
the rotation interchange any two of motor leads.
3. Never connect AC main circuit power supply to output termi-
nals T1 (U), T2 (V), and T3 (W).
4. Care should be taken to prevent contact of wiring leads with the
3G3SV cabinet, or a short-circuit may result.
5. Never connect power factor correction capacitor or noise filter
to 3G3SV output.
6. Never open or close contactors in the output circuit unless in-
verter is properly sized.
