7.1 MAINTENANCE
7.1.1 Introduction
WARNING!
To ensure an optimum operation of the CONCEPTPOWER DPA
of the connected load it is recommended to check the batteries every 6 months, depending on the ambiance
temperature.
7.1.2 User Responsibilities
There are no user serviceable parts contained within the UPS so the maintenance responsibilities of the user are
minimal. To maximize 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.
7.1.3 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 maximized. 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 trained or agreed service personnel and authorized 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/enivrement 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
7.1.4 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" section 4 / 4.1.3.5.
THE OPERATIONS DESCRIBED IN THIS CHAPTER MUST BE
PERFORMED BY A SERVICE ENGINEER FROM THE MANUFACTURER
OR FROM A AGENT AUTHORIZED BY THE MANUFACTURER.
