1. Overview

Personnel Requirements

Only qualified and trained electrical technicians are allowed to operate the SUN2000.

Operation personnel should understand the composition and working principles of the

PV grid-tied power system and local regulations.

Identification Protection

The signs on the SUN2000 shell specify important information about secure operation.

Do not damage the signs.

The nameplate attached to the SUN2000 side panel lists the SUN2000 parameter

information. Do not damage the nameplate.

Installation

Before installation, read this document carefully. Huawei shall not be liable for any

consequence caused by violation of the regulations specified in this document.

Before installing the SUN2000, ensure that the SUN2000 is not connected or electrified.

Install the SUN2000 in environments with good ventilation to ensure system

performance.

Ensure that the SUN2000 heat sinks are unblocked.

Do not move the components inside the shelf except the wiring terminals at the bottom.

Electrical Connection

Before connecting cables to the SUN2000, ensure that the SUN2000 is intact and secure.

Otherwise, electrical shocks or fire may be triggered.

Before connecting cables to the SUN2000, shield the PV modules by using opaque cloth.

All electrical connections must comply with local laws and regulations.

Before using the SUN2000 to generate electricity in grid-tied mode, obtain approval

from the local power supply department.

Ensure that the cables to the solar power system are properly connected and insulted

(That is, the insulation resistance between the ground and the main loop formed by PV

module strings, the SUN2000, and protective devices is less than 1 Mohm.) and meet

specifications.

Operation

High voltages may cause electrical shocks and death during SUN2000 operation. Strictly

comply with the safety precautions in this document and associated documents when

operating the SUN2000.

Do not disconnect the DC power supply during the SUN2000 operation.

Do not touch a running SUN2000 except for the liquid crystal display (LCD) and DC

switch because the shelf and heat sinks become hot during the SUN2000 operation.

Only professionals are allowed to set initialization parameters during the first power-on

of the SUN2000. Incorrect settings may affect the SUN2000 operation and cause the

SUN2000 to conflict with local certification.

Keep an over 20 cm distance away from the SUN2000 because radiation is generated

during the SUN2000 operation.

When operating the SUN2000, follow local laws and regulations.

Maintenance and Replacement

Before maintaining the SUN2000, disconnect power cables from the AC and DC side

and wait at least 5 minutes.

Stand temporary warning signs or fences to prevent unauthorized personnel to enter the

maintenance site.

Rectify the faults that compromise the SUN2000 security performance before restarting

the SUN2000.

A faulty SUN2000 requires overall maintenance. Contact the dealer if any fault occurs

inside the SUN2000.

Maintain the SUN2000 after you get familiar with this document and tools and testing

equipment are prepared.

When maintaining the SUN2000, wear ESD gloves and comply with ESD precautions.

To prevent device damage and personal injury, keep balance when moving the SUN2000

because the SUN2000 is heavy.

Do not put the SUN2000 with its wiring terminals contacting the floor because the power

ports and signal ports are not designed to support the weight of the SUN2000. Place the

SUN2000 horizontally.

When placing the SUN2000 on the floor, put foam or paper under the SUN2000 to protect

its shell.

4. Installing the SUN2000

If the installation location is near the ground, first connect the PGND cable to the ground before

installing the SUN2000 on the wall. For details, refer to 5 Connecting PGND Cables.

Step 1 Install the rear panel.

If you use a ladder to install the SUN2000 on a high position, keep balance to protect yourself

from falling down.

1. Determine the position for drilling holes, level hole positions, and then mark the hole

positions by using a marker, as shown in Figure 1-3.

Figure 1-3 Hole positions and dimensions

To ensure good heat dissipation and reserve enough space for installing the SUN2000,

the SUN2000 is at least 200 mm, 500 mm, 300 mm, and 1000 mm away from objects on

its both sides, top, bottom, and front respectively, as shown in Figure 1-4.

Figure 1-4 Minimum installation clearance

When installing multiple SUN2000s, install them in the same line if sufficient space is

available and install them in triangle mode shown in Figure 1-5. If no sufficient space is
