Servicing, Cleaning, And Inspecting To UPS

The UPS must turn-off before operation and cleaning. If the power cord not plugged in, the technician will begin servicing, cleaning, and inspecting each part. Ensures device integrity Professional technicians and devices that can connect to UPS. (APC distributor in Pakistan).

Check the general condition of the device.

  • Cleaning general equipment.
  • Adjust the mechanism of components and components of equipment.

UPS Preventive Maintenance Forms

These critical teams, such as UPS and A / C, who work at 24 7 intervals for all customers, are encouraged to perform preventive repairs on a monthly or up to bi-monthly basis. It is important to remember that a team works continuously for 720 hours a month and causes significant damage to the team and requires regular supervision by specialists.

Protect data center power with regular UPS maintenance

There are several levels of testing that must address when developing a UPS maintenance checklist. Be sure to perform visual, thermal, and load tests to verify the status of the UPS.

Maintaining the data center power infrastructure is essential for operational continuity. In addition to regular battery health assessment, you should also develop a maintenance plan for backup power options, such as uninterruptible power supplies.

Preventative Maintenance Plan

This type of preventative maintenance plan can not only reduce the amount of unexpected expenses, but also ensure that your data center will continue to have power in the event of an emergency or unexpected outage.

Although the specifics of an uninterruptible power supply (UPS) maintenance checklist vary from organization to organization, there are a few main areas that your team should address as part of regular operations or through a service provider.

Visual Inspection

Regular visual inspections are some of the most important steps you can take to keep your UPS healthy. You can do a partial walk-through inspection and look at the exterior of the unit, but a full inspection includes an examination of the internal components.(APC distributor in Pakistan).

However, doing so may expose you to dangerous electrical currents. Therefore, such inspection should only perform by qualified persons, such as an electrical engineer, facility electrician, or other third party.

For a partial visual inspection, look for any accumulation of dust or dirt. Dust can clog the device’s vents and cause it to overheat. The inspection should also include an evaluation of the battery. Watch for any signs of corrosion, leaks, or swelling, as these are indicators that the batteries need to replaced.

It is also a good idea to check the AC input and output capacitors, as well as the DC filter capacitors. Condensers must be clean and show no signs of cracking or swelling.

During a visual maintenance inspection of the UPS, don’t use just your eyes. You should also listen for unusual sounds and pay attention to abnormal odors; either could indicate the presence of a hardware problem. (APC distributor in Pakistan).

Thermal Scans for Important UPS Maintenance

Another important UPS maintenance task is a thermal scan that checks the temperature around the UPS to ensure it is within the manufacturer’s operating specifications.

Check The UPS Temperature

One way to check the UPS temperature is to use a non-contact infrared thermometer to measure the chassis surface temperature. If your UPSs are fan-cooled, you can also use a thermometer to check the temperature of the air leaving the units.

If your organization has many UPSs to check, a thermal imager may be more efficient to use. A thermal imaging camera creates a heat-based image that makes it easy to locate thermal anomalies among your UPS systems.

Load And Load Test

Load tests are essential for UPS maintenance. A load test checks the UPS’s ability to power your data center hardware in the event of a power outage and how much power the source can handle. Load tests require careful planning so they do not jeopardize production workloads.

There are several different types of load tests, some of which require specialized knowledge and should only performed by a qualified technician. Load tests can involve more than just a battery depletion. Normal burden test types incorporate consistent state load tests, consonant investigation, and a transient reaction load test.

Although the tests have similar names, a load test and a load bank test are different procedures. (APC distributor in Pakistan).

Load Bank Test

Like a load test, a load bank test checks the UPS’s ability to provide a predetermined amount of sustained power. These tests use specific hardware known as load banks to test the UPS batteries. These banks provide the different power levels for testing the UPS; load bank tests do not look at the unit’s overall ability to power data center hardware.

An important consideration for load bank testing is that load banks are like heating elements. As such, you should test the load bank with fire safety in mind and away from alarms or sprinklers.

If you are performing a load test or load bank test, it is essential to ensure that the UPS batteries fully charged during the test. Otherwise, the test results are invalid.

Verification Of Alarms and Calibration Of UPS

Another important maintenance task is to periodically verify that each UPS is communicating correctly with your monitoring software. As you do so, review the alarm log for each UPS for any indication that the UPS may be experiencing abnormal behavior.

UPS Units Are Properly Calibrated

A trained technician should periodically ensure that the UPS units are properly calibrated. A UPS that is not properly calibrated can trigger an overvoltage alarm, even if the supported load is within the rated power range of the device. It can also cause the drive to display incorrect runtime data, making it difficult to schedule required maintenance.

UPS Maintenance

As important as proper UPS maintenance is, UPS maintenance does not replace the hardware upgrade cycle. UPS batteries, even if not used, have a limited lifespan. As such, the UPS batteries should replace periodically in accordance with the manufacturer’s recommendations.
