Routine maintenance hel s the O&M ersonnel to:
Find and handle alarms related to equi ment o erating in a timely manner.
Discover otential risks in a timely manner, reventing faults that could ossi
bly cause economic losses and reduce customer satisfaction.
Analyze the system o erating trend based on collected information and take meas
ures to
im rove o erating efficiency.
Precautions
Read all the recautions and roduct documentation before erforming routine
maintenance.
Follow local laws and safety instructions to minimize the risk of ersonal inju
ry and damage to equi ment. The "NOTICE", "CAUTION", "WARNING", and "DANGER“ s
tatements in this document do not re resent all the safety instructions. They a

Pay attention to the safety symbols on the equi ment and all safety instruction
s in this document. The safety recautions given in this document do not cover
all safety recautions. Huawei will not be liable for any consequence caused by

If you need to erform maintenance tasks such as measuring the current, voltage
, and tem erature when the equi ment is o erating, connect the ower su ly onl
y after you have finished all equi ment connections. Disconnect the ower su l
y when you finish maintenance.
