Maintenance
This chapter introduces basic maintenance requirements, routine maintenance items, maintenance operations, basic fixing
methods and emergency treatment.
NOTE!
1. The maintenance must be conducted under the guidance of related safety regulations. 2. Even if the system
disconnects all AC inputs and battery inputs, the rectifier capacitor still needs to discharge for a period of time. After
measuring the DC bus voltage is below the safety voltage by a multimeter, then you can maintain DC bus and device
connected to the DC bus.

General
To ensure quality power supply and guarantee stable and reliable operation of the communication system, operation
management and maintenance are necessary to the power system. Basic requirements for maintenance of power system include:
1. Guarantee uninterrupted quality power supply to the communication equipment.
2. Carry out periodic inspection and overhaul to ensure stable and reliable operation of the power system and prolong its
operational life span.
3. Conduct effective troubleshooting to reduce the loss caused by faults.
4. Keep the equipment and environment clean to ensure that the environment in the equipment room conforms to the basic
requirements of equipment operation.
5. Use new technologies and improve maintenance methods to achieve centralized monitoring, little or even no attendance.
To sum up, the power system maintenance includes routine maintenance, periodic inspection and technological reform. And the
maintenance must be carried out in compliance with applicable industry standards and local regulations.
