WIRING
CAUTION
Make sure to connect the power cables to the right terminals: one set to terminals R/L1, S/L2, and T/L3, and the other
set to terminals R2/L12, S2/L22, and T2/L32.
When wiring the main circuit conductor tighten each nut from the right side of the conductor as seen from the front of
the unit. When wiring two wires, place wires on both sides of the conductor. For wiring, use bolts and nuts removed
earlier for these connections (refer to the drawing).
For 12-pulse applications, make sure to remove all of the shorting conductors between terminals R/L1 and R2/
L12, between terminals S/L2 and S2/L22, and between terminals T/L3 and T2/L32 of the converter unit. If the
power transformer is connected without removing these conductors, it may be burned.
Check the correct connection between the output terminals in the star/delta connection of the power
transformer and the terminals of the converter unit. Otherwise a burst, damage, etc. may occur in the
converter unit or the power transformer.
