1 Safety Precautions
Read the safety precautions carefully to ensure human safety.
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.

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.
