Maintenance
5.1 Introduction
5.2 System calibration
To ensure optimum UPS operation and continuous, efficient protection of the connected load, it is
recommended that the system’s operating parameters are checked every six months and recalibrated where
necessary. The batteries should also be checked every six months, depending on the ambient temperature.
5.3 User responsibilities
There are no user-serviceable parts contained within the UPS so the maintenance requirements of the user
are minimal. To maximise the useful working life and reliability of the UPS and its batteries, the environment
in which the UPS operates should be kept cool and dust free.
5.4 Routine maintenance
It is essential that the UPS system and batteries receive regular preventative maintenance inspection to
maximise both the useful working life and the reliability of the UPS system. When the UPS is commissioned,
the commissioning field service engineer will attach a service record book to the front of the UPS which will
be used to log the full service history of the UPS.
Preventative maintenance inspections involve working inside the UPS which contains hazardous AC and DC
voltages.
During a preventative maintenance inspection the field service engineer will check:
• Site/environment conditions
• Integrity of electrical installation
• Cooling airflow
• Rectifier operation and calibration
• Inverter operation and calibration
• Static switch operation
• Battery status
• Load characteristics
• Integrity of alarm and monitoring systems
• Operation of all installed options
Preventative maintenance inspections form an integral part of all Extended Warranty Agreements
(maintenance contracts) offered by Kohler Uninterruptible Power.
For further details on Extended Warranty Agreements see Paragraph 2.6.
WARNING: All the operations described in this chapter must be performed by authorised
electricians or otherwise qualified personnel.
WARNING: Only Kohler Uninterruptible Power trained and authorised field service engineers
are fully aware of all of the hazardous areas within the UPS.
