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
