The single-phase AC power cable for the smart array controller needs to be prepared by
the customer. You are advised to use a two-core outdoor armor copper cable with an
operating voltage to the ground greater than or equal to 300 V and a cross-sectional area of
4 mm
2
for each core wire.
The power cable from the miniature circuit breaker (MCB) to the station-service power
source needs to be prepared by the customer. You are advised to use a two-core outdoor
armor copper cable with an operating voltage to the ground greater than or equal to 300 V
and a cross-sectional area of 4 mm
2
for each core wire.
The three-phase AC power cable for the smart array controller needs to be prepared by the
customer. You are advised to use a four-core (L1, L2, L3, and functional earthing) outdoor
armor copper cable with a cross-sectional area of 10 mm
2
for each core wire as the
three-phase AC power cable. 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 to the ground of
the three-phase AC power cable 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 to the ground of the three-phase AC
power cable should be greater than or equal to 1000 V.
The cable from the busbar to the three-phase power switch needs to be prepared by the
customer. You are advised to use a four-core multi-wire (L1, L2, L3, and functional
earthing) outdoor armor cable with a cross-sectional area of 10 mm
2
for each core wire as
the cable from the busbar to the knife switch. 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 to the ground of the cable 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 to the ground of the cable should be
greater than or equal to 1000 V.
