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.
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.
Before any maintenance, power off the SUN2000 based on the power-off guidelines and
then wait for 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.
