Maintenance

5.1
Introduction
WARNING: Do not remove the covers from the UPS case. If you remove a cover from the UPS case you will
be exposed to potentially lethal voltages.
The UPS does not contain any user-serviceable parts, so the day-to-day maintenance requirements are minimal other
than to ensure that the environment in which the UPS is installed is kept cool and dust free. A clean, controlled operating
environment will help maximise the useful working life and reliability of both the UPS and its batteries.
5.2
Scheduled maintenance
The UPS system and batteries should receive regular preventative maintenance from a trained engineer to maximise both
the useful working life and system reliability. If the UPS is commissioned by a Uninterruptible Power Supplies Ltd. service
engineer, the engineer will leave a service record book with the UPS which will be used to log its full service history.
We recommend that the UPS system is maintained every six months by an Uninterruptible Power Supplies Ltd. trained
engineer or approved service agent, who will complete the following. Preventative maintenance inspections form an
integral part of all Extended Warranty Agreements (maintenance contracts) offered by Uninterruptible Power Supplies Ltd.
5.2.1 Preventative maintenance inspection
During a preventative maintenance inspection a trained Uninterruptible Power Supplies engineer will check and validate:
• Site environmental conditions
• Integrity of the electrical installation
• Cooling airflow
• Load characteristics
• Integrity of alarm and monitoring systems
• Operation of all installed options
• All stored event logs
5.2.2
Battery maintenance and testing
The batteries should be inspected and tested every six months, depending on the ambient temperature.
The battery test takes approximately two minutes to complete and can be performed only if:
• There are no alarm conditions present.
• The battery is fully charged.
• The UPS input mains supply is present.
The battery test procedure can be carried out from the UPS front panel and performed irrespective of the UPS operating
mode (ON-INVERTER or ON-BYPASS/ECO) and whether or not the load is connected.
