Fault diagnosis and repair
Alarm logs, operating status and relevant components are examined to identify the cause of the fault. Necessary repairs and component replacements are then planned.

Our services
Our UPS technical services
A UPS fault is not always caused by the batteries. The charging circuit, fans, electronic boards, connections or connected load may also be responsible. We first assess when and how the fault occurs, then use the relevant measurements and checks to determine the repairs needed.
Preventive UPS maintenance
The battery bank, fans, connections and overall condition of the unit are checked. Input and output readings, load level and environmental conditions are assessed.
Battery testing and replacement
Measurements are used to assess the battery bank. Where replacement is needed, suitable batteries are selected according to the technical requirements of the UPS.
On-site UPS service
The service approach takes account of the installation environment and your operating schedule. A quote can also be prepared for a preventive maintenance agreement.
Maintenance scope
What is checked during preventive UPS maintenance?
A UPS that appears to be running normally may not provide the expected backup runtime during a power outage. Reduced battery capacity or a cooling problem can go unnoticed during everyday operation. Preventive UPS maintenance helps identify these issues and plan the work required.
Checks are selected according to the system design and the manufacturer’s maintenance instructions. The main areas that may be assessed include:
Battery bank and charging system
Battery voltages, physical condition, connections and charging readings are checked. Battery performance is assessed using an appropriate test method where required.
Fans and ventilation
Fan operation, air inlets and outlets, dust buildup and the unit’s cooling conditions are inspected.
Electronic boards and capacitors
Components are checked for visible signs of deterioration and overheating. Further measurements or replacement needs are assessed according to their condition.
Input, output and load readings
Voltage, current and load level are assessed. The UPS rating is considered alongside the power requirements of the connected equipment.
Connections and operating environment
Cables and connection points, ambient temperature, humidity and ventilation clearances around the unit are checked.
Alarm logs and operating status
Available fault logs are reviewed. Functional tests are planned with the connected equipment’s shutdown requirements in mind.
Work requiring a power interruption or transfer to bypass should be scheduled in advance to suit your operations.
Business maintenance
Annual UPS maintenance agreements
For businesses with several UPS units, keeping track of maintenance dates and equipment condition is essential. An annual maintenance agreement can define the inspection frequency, scope of work and service terms in advance.
To prepare a quote, we need the make and model, power rating, quantity, location and operating conditions of the units. The quote should clearly state whether battery and spare part replacements, fault response and scheduled maintenance visits are included.
Battery service
UPS battery testing and replacement
If backup runtime during a power outage has fallen noticeably, the battery bank should be checked. However, replacing the batteries alone may not resolve a charging system fault or an overload issue. The UPS and its battery bank are assessed together before replacement.
Replacement batteries are selected according to the required battery type, voltage, capacity, connection arrangement and manufacturer specifications. Browse our battery range or request a replacement quote for your existing UPS.
Warning signs
When should your UPS be checked?
- The unit shuts down during a power outage or cannot support the load for the expected duration.
- A battery, overload, temperature or fan alarm appears.
- The unit switches to bypass mode unexpectedly.
- You notice unusual noise, overheating or recurring faults.
- Maintenance is overdue, or the connected load or operating environment has changed.
These symptoms do not establish a diagnosis on their own. Contact a qualified service team before attempting to work on internal components or battery connections.
Process
How does the service process work?
- Send your request.Share the make, model, power rating, location and any alarm code.
- Agree on the service scope.We assess the checks required, service method and a suitable time for the work.
- Plan the maintenance or repair.The work and quotation are defined according to the identified needs.
- Check operation after the work.The unit’s condition is assessed using checks appropriate to the work performed.
FAQ
Frequently asked questions about UPS service and maintenance
What does UPS technical service include?
UPS technical service covers fault diagnosis, an assessment of operating conditions, battery and connection checks, inspection of fans and electronic components, maintenance and any necessary repairs. The work required depends on the make, model and condition of the unit.
What should I do if my UPS shuts down as soon as the power fails?
Possible causes include reduced battery capacity, a charging system fault or a connected load that exceeds the UPS rating. The batteries, charging system and load should be checked together to identify the cause. When requesting service, share the make and model, connected load and any alarm code.
How often should preventive UPS maintenance be carried out?
The maintenance interval depends on the manufacturer’s recommendations, usage, ambient temperature, dust levels and how critical the connected equipment is. Critical systems and demanding environments may require more frequent checks. A suitable maintenance schedule is established after a technical assessment.
How can I tell whether my UPS batteries need replacing?
Shorter backup runtime, battery alarms or a faster-than-expected voltage drop under load are signs that the batteries should be checked. Replacement decisions should consider test results, operating conditions and manufacturer recommendations, rather than battery age alone.
Can UPS batteries be replaced while the system is running?
This is not possible on every system. The battery configuration, manufacturer instructions, bypass arrangement and connected load must be assessed first. The technical team determines whether replacement can be carried out during operation or whether a planned shutdown is needed.
Is my equipment protected when the UPS is in bypass mode?
In bypass mode, the load is generally supplied through the bypass line rather than the UPS inverter. Power conditioning and battery backup may therefore differ from normal operation or may not be available. Protection depends on the UPS design and type of bypass. The reason for entering bypass mode should be investigated.
Do you provide on-site UPS service?
You can contact ELSIPOWER to request on-site service. We assess the location, make and model, nature of the fault and work required before arranging the appropriate service method and visit. Some repairs may require the unit to be taken to a service facility.
How are UPS service and preventive maintenance prices calculated?
Pricing depends on the UPS rating, make and model, extent of the fault, required spare parts or batteries, and service conditions. Send us the equipment details and a description of the issue to request a maintenance or repair quote.
What information should I provide when requesting service?
Please include the make and model, kVA or kW rating, serial number, installation address, any alarm code shown on the display and when the problem occurs. Photos of the equipment label and display are also helpful.
Request UPS service or maintenance
Call or email us for a UPS technical service or preventive maintenance quote. Please include the make, model, power rating and location so we can assess your request. If there is a fault, include any alarm code and a photo of the display where possible.
