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
As there are no user-serviceable parts contained within the UPS, the maintenance required by the user are minimal apart
from keeping the equipment clean and monitoring the working environment to ensure it is kept cool and dust-free. This will
maximise the useful working life and reliability of the UPS and its batteries.
5.4
Routine maintenance
It is essential that the UPS system and batteries receive regular preventative maintenance inspection. When the UPS is
commissioned, the commissioning field service engineer will attach a service record book to 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 and
should only be performed by authorised service personnel.
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 optional equipment
Preventative maintenance inspections form an integral part of all Extended Warranty Agreements (maintenance contracts)
offered by Uninterruptible Power Supplies Ltd.
WARNING:
The UPS contains hazardous voltages even when switched off.
WARNING:
Do not remove the UPS covers unless you are electrically qualified and trained on the
equipment type by the manufacturer (Uninterruptible Power Supplies Ltd) or one of its service agents.
WARNING:
There are no user-serviceable part contained within the UPS.
WARNING:
Any operation described in this chapter that requires internal access to the UPS or external
battery cabinets must be performed by authorised service personnel.
