1 Precautions
General Safety
Personnel who plan to install or maintain Huawei equipment must receive a thorough training,
understand all necessary safety precautions, and be able to correctly perform all operations.
Only trained and qualified personnel are allowed to install, operate, and maintain Huawei
equipment.
Only trained and qualified personnel are allowed to remove safety facilities and inspect
the devices.
Only personnel certified or authorized by Huawei are allowed to replace devices or
components (including software).
Installation personnel must report faults or errors that might cause serious safety issues
to related owners.
The safety precautions given in this document do not cover all the safety precautions. Huawei
will not be liable for any consequence caused by the violation of the safety operation
regulations and design, production, and usage standards.
Local Safety Regulations
Follow local laws and regulations when operating the device. The safety instructions in this
document are only supplementary to the local laws and regulations.
Grounding
Equipment to be grounded must meet the following requirements:
When installing a device, install the ground cable first. When uninstalling a device,
remove the ground cable at the very end.
Do not damage the ground conductor.
Do not operate the device in the absence of a properly installed ground conductor.
The device must be connected permanently to the protection ground before any
operation.
Before operating the device, check the electrical connection of the device to ensure that
it is securely grounded.

Personal Safety
Before any operations, take off conductive objects such as jewelry and watches to avoid
electric shocks or burns.
For personal safety, wear insulation gloves and safety shoes during operation and
maintenance (O&M).
Use tools in correct methods to avoid hurting people or damaging devices.
In the case of fire, immediately leave the building or the equipment room, and turn on
the fire alarm bell or make an emergency call. Do not enter a building that is on fire.
When the operation is performed in a damp environment, ensure that the device is dry.
When water is found in the rack or the rack is damp, switch off the power supply
immediately.
Equipment Safety
The device must be secured on the floor or to other immovable objects such as walls and
mounting supports before operation.
Tighten the screws by using a tool when installing components.
After the installation, remove packing materials from the equipment area.
High Voltage
The high voltage power supply provides power for the device operation. Direct or indirect
contact (especially with a damp object) with the high voltage power supply may result in
fatal injury.
Non-standard and improper high voltage operations may result in fire and electric shocks.
Personnel who install AC facilities must be qualified to perform high voltage and AC
operations.
You must abide by the local rules and regulations when bridging and routingAC cables.
Follow the local laws and regulations when installing AC power facilities.
Use dedicated tools when performing high voltage and AC operations.
Put on insulation gloves before powering on or off cabinets.
Power Cables
Do not connect or disconnect power cables under power. Transient contact between the core
wire of the power cable and the conductor will generate electric arcs or sparks, which may
cause fire or personal injury.
Before connecting or disconnecting a power cable, turn off the upstream power switch,
and use a multimeter to check that the AC and DC voltages of the input port are zero.
Before connecting a power cable, check that the label on the power cable is correct.

Do not mix up the single-phase AC power cable with the three-phase AC power cable
when connecting cables. Otherwise, the device may be damaged.
Components
To ensure that a device runs safely, replace a failed device component with a component of
the same model and specifications.

2 Overview
2.1 Product Introduction
Features
The smart array controller is an outdoor cabinet that houses the SmartLogger2000
(SmartLogger for short), potential induced degradation (PID) module, power line
communication central controller module (PLC CCO module, in the dual-split transformer
scenario), local area network (LAN) switch, access terminal box (ATB), power over Ethernet
(POE) module, POE surge protective device (SPD), and so on.
The SmartLogger installed in the cabinet collects data from PV devices and reports the data to
the plant monitoring system over a fiber ring network or 4G LTE network to control the
communication between the PV plant and the monitoring system. The SmartLogger that has
the embedded PLC function can connect to a SUN2000 integrated with the PLC function. In
the scenario with a dual-split transformer, use a smart array controller that supports the access
of two PLC routes, that is, the smart array controller that is factory-installed with an
independent PLC CCO module and a SmartLogger with the built-in PLC function.
PV devices include the SUN2000, box-type transformer, video surveillance device, and environmental
monitoring instrument (EMI), and so on.
The smart array controller can be factory-installed with a PID module to prevent PID effect
on PV modules, thereby increasing the energy yield and benefit.
The smart array controller can be installed on a wall, support, or pole. The front door can be
opened for maintenance, which facilitates installation, cable connection, and future
maintenance.
