What maintenance work is required for EPS system?
Routine maintenance of the EPS system is the key to ensure its reliable operation in emergency situations. Here are some important maintenance steps and considerations:
Follow the manufacturer's maintenance recommendations
According to NFPA 110, the maintenance of EPS systems shall follow the manufacturer's maintenance recommendations, instructions, the minimum requirements of this chapter, and any additional requirements of the jurisdiction.
Maintenance and operation test plan
Routine maintenance and operational test plans should be initiated as soon as EPSS passes acceptance tests or repairs that affect the reliability of system operation are completed.
Operation test
Operational testing shall begin with the Automatic transfer switch (ATS) and include testing of each EPSS component that has been maintained or repaired, including the transfer of each automatic and manual transfer switch to a standby power supply for at least 30 minutes at operating temperature.
Transfer switch maintenance and testing
Transfer switches should be maintained and tested, including checking connections, checking for signs of overheating and excessive contact wear, removing dust and dirt, and replacing contact points if necessary.
Inspection of parallel devices
Parallel units should be inspected, tested and maintained, including checking connections, checking for signs of overheating and excessive contact wear, removing dust and dirt, replacing contact points if necessary, and verifying that system controls will operate as intended.
Battery inspection and maintenance
Batteries for the system, including electrolyte levels or battery voltages, should be checked weekly and fully comply with the manufacturer's specifications. Maintenance of lead-acid batteries includes monthly testing and recording the specific gravity of the electrolyte.
Equipment appearance maintenance
Regularly clean the dust and debris on the surface of the device, check the integrity of the device shell and cable, and replace it in time if necessary.
Battery Management
Periodically check whether the battery wiring is loose, whether the battery compartment is clean, and clean the corrosion on the surface of the battery compartment. Check whether the battery capacity and voltage are normal. If the battery capacity drops rapidly or the voltage is abnormal, replace or repair the battery in time.
Power Management
Periodically check that the voltage, frequency and current of the input and output of the power supply are stable and normal. Check whether the fans inside the power supply are running properly. If any fan is abnormal, clean and replace it in time.
Record keeping
All records of maintenance, testing and inspection shall be kept in detail and at least for the period specified by the competent authority.
Generator maintenance
The generator should be run for at least 30 minutes at least once a month to ensure that it can meet the manufacturer's recommended minimum exhaust gas temperature or exceed 30% of the standby power rating.
Transfer switch monthly operation
The transfer switch must be operated every month to electronically transfer from the primary location to the secondary location and then back to the primary location to meet monthly maintenance requirements.
CONCLUSION
By following these maintenance steps, you can ensure that the EPS system can provide reliable emergency power when needed.
