Maintenance
THE OPERATIONS DESCRIBED IN THIS CHAPTER MUST BE PERFORMED BY A SERVICE
ENGINEER FROM THE MANUFACTURER OR BY AN AGENT CERTIFIED BY THE
MANUFACTURER.
WARNING!
8.1
User Responsibilities
There are no user servicable parts within the UPS, therefore there is no requirement for user maintenance. To maximize the useful
working life and reliability of the UPS system 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 maintained in a fully charged state.
8.2
Preventative Maintenance
The UPS system requires annual preventative maintenance by authorized service personnel, even during the warranty period, to ensure
proper, reliable operation.
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 air ventilation and room temperature
• Check the operation and function (communications, 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
8.3
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
• mains is present.
The battery testing can be carried out regardless of operating mode(OFF-LINE or ON-LINE) and whether or not the load is connected.
The battery test procedure can be performed from the UPS display in the service setup mode.
8.4
Battery Maintenance, Disposal, and Recycling
The battery maintenance shall be done by a certified Service Partner.
To ensure optimum operation of the UPS system and a continuous and efficient protection of the connected load, it is recommended to
check the batteries every 12 months.
Batteries contain dangerous substances that will harm the environment if thrown away. If you change the batteries yourself, call qualified
organizations for battery disposal and recycling.
