5 Maintenance
5.1 INTRODUCTION
ALL THE OPERATIONS IN THIS SECTION MUST BE PERFORMED BY AUTHORISED
ELECTRICIANS OR BY QUALIFIED INTERNAL PERSONNEL.
To ensure an optimum operation of the
PowerValue
TM
and a continuous and efficient protection of the
connected load it is recommended to check the batteries every 6 months, depending on the ambiance
temperature.
5.2 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. The
batteries should be hold fully charged.
5.3 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 NEWAVE trained or agreed service personnel 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;
•
Static switch operation;
•
Battery status;
•
Load characteristics;
•
Integrity of alarm and monitoring systems;
•
Operation of all installed options;
5.4 BATTERY
TEST
The battery test takes approx. 3 minutes and should be performed only if:
•
there are no alarm conditions;
•
the battery is fully charged;
•
mains is present.
The battery testing can be carried out independently of the operation mode (OFF-LINE or ON-LINE)
and whether or not the load is connected.
The battery test procedure can be performed from the UPS front panel. See “Operation” Chapter 4.
