Recommended Model or Specifications
⚫
Four-core (L1, L2, L3, and functional earthing)
outdoor copper armored cable with three OT-M6
terminals (L1, L2, and L3) and one OT-M4
terminal (functional earthing)
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.
CAT 5E outdoor shielded network cable with an
outer diameter less than 9 mm (0.35 in.) and internal
resistance not greater than 1.5 ohms/10 m (1.5
ohms/32.81 ft), as well as a shielded RJ45
connector
