Components listed in the table need to be installed onsite.
Select either an MCCB or a knife fuse switch as the three-phase power switch. If you
select an MCCB, ensure that the let-through energy of the MCCB meets requirements. The
breaking capacity depends on the limited short-circuit current on the low voltage side of
the transformer.
Models of the components inside the box-type transformer are specified by the box-type
transformer vendor.
Note a: If the CPE model is EG860, configure a POE SPD.
Cable Name/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
A computer cable (DJYP2VP2-22 2x2x1) or
