UPS service ensures the availability of critical consumers, reduces unplanned outages and creates transparency about the maintenance status, battery aging and malfunctions. ERREPI supports companies from testing and technical assessment to commissioning and maintenance and replacement of existing UPS systems - reliably, manufacturer-independent and practice-oriented.
Service for active UPS systems
One UPS is only reliable if its technical condition is checked regularly. Not only the system itself is crucial, but also the condition of the batteries, the connected load and the integration into the existing infrastructure. That's why a professional UPS service takes all relevant factors into account - from battery age, installation location and bypass concept to messages, operating data and technical documentation.
Typical applications include regular maintenance, replacing old batteries, commissioning new systems, analyzing faults or unclear bridging times, and checking whether an existing UPS still meets the current performance requirements.

Maintenance and recurring testing
Maintenance serves to identify visible and hidden risks early. This includes visual inspection, operating status, fan, environment, battery, error memory, load level, bypass function and the plausibility of the reported values.
For critical applications, maintenance should be planned and documented. Particularly important are the battery condition, ambient temperature, air flow and the question of whether the load can continue to be safely supplied in the event of maintenance.
Battery replacement and battery condition
The battery is a wearing part. Your usable capacity depends on age, temperature, discharge profile and state of charge. A timely planned replacement is usually cheaper and safer than a failure under load.
A battery replacement includes the appropriate replacement batteries, safe replacement, functional testing and correct disposal of used batteries. If the desired Autonomy time is no longer achieved, the load and design should also be checked.
Commissioning and expansion
When it comes to new or replaced systems, it's not just switching on that counts. Commissioning means checking the device, battery, connected load, fuse protection, environment and operating mode together.
Depending on the system, this includes functional testing, controlled battery operation, bypass testing, interface configuration, reporting test and short instruction. For server room and network applications, integration into monitoring or shutdown processes can also make sense.
Fault diagnosis and repair
Alarm messages, short backup times, battery errors, overload, switching problems or unusual noises should not be viewed in isolation. What matters is whether the cause lies in the device, the battery, the load, the environment or the electrical installation.
Device type, serial number, error messages, load data, environmental conditions, photos of the installation and existing protocols help with diagnosis. If a repair does not make economic or technical sense, the replacement or modernization option should also be evaluated.
Monitoring, SNMP and notifications
Monitoring makes conditions visible before a disruption becomes a failure. Over SNMP adapter or potential-free contacts, UPS systems can pass on messages to IT and building technology.
When it comes to IT loads, it is also important whether servers, storage or network components should be shut down in a controlled manner in the event of longer network failures. To achieve this, the UPS, software, network and responsibilities must fit together.
Typical process for a service request
- Describe the existing installation, problem or desired service.
- Provide device data, battery date, load and location information.
- Clarify the scope of services: maintenance, battery replacement, diagnosis, commissioning or monitoring.
- Agree on the offer, date and necessary preparations.
- Document implementation and record follow-up measures.
Helpful information in advance
This information is helpful for a quick classification:
- Manufacturer, model, power and serial number of the UPS.
- Age of the system and date of last battery replacement.
- Connected consumers and estimated load in Watt or VA.
- Desired autonomy time or current runtime problem.
- Error messages, event logs or photos of the display.
- Installation location, ambient temperature and accessibility.
- Existing bypass, SNMP card or monitoring connection.
Quality management according to ISO 9001
ERREPI works with certified processes according to ISO 9001. When it comes to UPS service, maintenance, battery replacement and troubleshooting, quality management supports comprehensible processes, clear responsibilities and documented results.
