Maintenance
5.1 Introduction
As the UPS contains no user-serviceable parts, the maintenance requirements to be carried out by the user
are minimal beyond ensuring that the UPS operating environment remains suitably cool and dust-free.
5.2 Routine maintenance
We recommend that the UPS operating parameters are checked and recalibrated annually as part of a
regular maintenance schedule to ensure optimum UPS operation efficient load protection. The batteries
should also be checked annually, depending on the ambient temperature.
When the UPS is commissioned, the commissioning 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.
During a preventative maintenance inspection the service engineer will check the following:
• Site environmental conditions
• Integrity of the electrical installation
• Availability and quality of the cooling airflow
• UPS Rectifier operation and calibration
• UPS Inverter operation and calibration
• UPS Static switch operation
• Battery condition and status
• Load characteristics
• Integrity of the 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 Uninterruptible Power Supplies Ltd. For further details on Extended
Warranty Agreements see Section 2 of this manual.
5.3 Battery Testing
The battery test procedure can be activated from the UPS operator panel and can performed independently
of the UPS operating mode (Off-line or On-line) and whether or not the load is connected.
WARNING: All the maintenance operations described in this chapter must be performed by an
authorised electrician or other suitably qualified personnel.
WARNING: Preventative maintenance inspections entail working inside the UPS with safety
covers removed. This presents a risk of electric shock due to the unavoidable exposure to
hazardous AC and DC voltages, and should be undertaken only by trained engineers
authorised by Uninterruptible Power Supplies Ltd. who are fully aware of the hazardous areas.
