MAINTENANCE
WARNING!
THE OPERATIONS DESCRIBED IN THIS CHAPTER MUST BE PERFORMED BY A
SERVICE ENGINEER FROM THE MANUFACTURER OR FROM AN AGENT CERTIFIED BY
THE MANUFACTURER.
7.1.1
User Responsibilities
There are no parts within the UPS which need to be serviced by the user, so the maintenance responsibilities of
the user are zero. 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 (20°C - 25°C), dry, dust free and vibration free. The batteries
should be hold fully charged.
7.1.2
Preventative Maintenance
The UPS system needs a regular and constant maintenance (preventative inspections) at least once a year, even
during the warranty period.
These preventative maintenance inspections are essential to ensure a correct functionality and reliability of the
UPS system. 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.
During a preventative maintenance the field service engineer might carry out some or all of following checks:
Status and function check of UPS and batteries
UPS and batteries visual inspection (dust, mechanical damages, ..)
Visual inspection of screws and cable connections
Check of air ventilation and room temperature
Check the operation and function (commutations, remote monitoring and Signaling)
Current, voltage and frequencies measures
Measure and record the current load conditions
Check the load sharing (only in parallel systems)
Battery voltage check
Battery discharge test
Check transfer of the load from UPS to mains operation via static bypass
Unit cleaning
7.1.3
Deep 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
