Maintenance
7.1 Introduction
ALL THE OPERATIONS IN THIS SECTION MUST BE PERFORMED BY
AUTHORISED ELECTRICIANS OR BY QUALIFIED INTERNAL
PERSONNEL.
TO ENSURE OPTIMUM OPERATION OF THE PowerWAVE 9000 DPA
SERIES UPS AND CONTINUOUS AND EFFICIENT PROTECTION OF
THE CONNECTED LOAD IT IS RECOMMENDED THAT THE
OPERATIONAL PARAMETERS AND CALIBRATIONS OF THE UPS
AND THE BATTERIES ARE CHECKED EVERY 6 MONTHS.
7.2 User
Responsibilities
There are no user serviceable parts contained within the UPS so the
maintenance responsibilities 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, dry, dust and
vibration free.
7.3 Routine
Maintenance
The UPS is designed to receive regular preventative maintenance
inspections. These preventative maintenance inspections are essential to
ensure that both the useful working life and the reliability of the UPS are
maximised. When the UPS is commissioned, the commissioning field
service engineer will attach a service record book to the front of the UPS
and this will be used to record the full service history of the UPS.
Preventative maintenance inspections involve working inside the UPS
which contains hazardous AC and DC voltages. Only Uninterruptible
Power Supplies Ltd. trained and authorised field service engineers are fully
aware of all of the hazardous areas within the UPS.
During a preventative maintenance inspection the field service engineer
will carry out the following checks:
•
Site/environment conditions.
•
Integrity of electrical installation.
•
Cooling airflow.
•
Rectifier operation and calibration.
•
Inverter operation and calibration.
