Recommended Model or Specifications
Three-core (L1, L2, and L3) outdoor copper

armored cable with three OT-M6 terminals (L1,
L2, and L3)
When the rated AC voltage on the low-voltage

side of the box-type transformer is less than or
equal to 500 V, the operating voltage between
the three-phase AC power cable and the
ground should be greater than or equal to 600
V.
When the rated AC voltage on the low-voltage

side of the box-type transformer is greater than
500 V and less than or equal to 800 V, the
operating voltage between the three-phase AC
power cable and the ground should be greater
than or equal to 1000 V.
