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.
