Typical Cable Connection Scenarios
2.1 Smart Array Controller Scenario

This document describes the application scenario where the SmartLogger is inside the smart
array controller SmartACU2000B-D-2PID/2PLC.
 The tables under figures list only the components to be configured by the customer in the
corresponding scenario.
NOTICE
1. Prepare the single-phase AC power cable for the smart array controller by yourself.
Recommended: 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. Prepare the power cable from the miniature circuit breaker (MCB) to the station-service power
source by yourself. Recommended: 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
core wire
3. Prepare the three-phase AC power cable for the smart array controller by yourself. Recommended:
a four-core (L1, L2, L3, and functional earthing) outdoor armor copper cable with a cross-sectional
2
area of 10 mm for each core wire. 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.
4. Prepare the power cable from the busbar to the Three-phase power switch by yourself.
Recommended: a four-core (L1, L2, L3, and functional earthing) outdoor armor copper cable with a
cross-sectional area of 10 mm
side of the box-type transformer is less than or equal to 500 V, the operating voltage to 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 to the ground should be greater than or equal to 1000 V.
