Most sine wave inverters are serviced after they are powered off, not while they are still energized. This is because powering off the equipment before it is serviced helps protect the servicer and the equipment. However, there are some situations in which an inverter must be serviced while still energized, such as when the inverter serves environments that must retain maximum power capacity at all times (e.g., hospitals and data centers). If your company or organization needs to service energize inverters, below are four essential tips for the task.

1. Wear the Right Personal Protective Equipment

Step one is for servicers to outfit themselves with the proper personal protective equipment (PPE) for the job. There are different levels of PPE. If you aren’t sure what level of protection to provide workers who service your company or organization’s sine wave inverters, refer to this helpful resource from OSHA that outlines PPE requirements in terms of hazard assessment.

2. Use a Dielectric Cleaner That Evaporates Quickly

Dielectric material repels the conduction of electricity. Consequently, if you need to clean an inverter that is still energized, using a dielectric cleaner imperative for safety. If there isn’t a solvent waste trap beneath the inverter (there usually is not), it’s also helpful to use a dielectric solvent that evaporates quickly, as this can help prevent slip and fall injuries in the work area.

3.Use a Dielectric Cleaner That has No Flashpoint

Ideally, you should also select a dielectric cleaner that has no flashpoint, which means that the solution will not combust regardless of the ignition sources to which it is exposed. Using a cleaner that has no flashpoint is also helpful for storage purposes. Cleaner that has no flashpoint can often be stored alongside combustibles without increasing the risk of fire.

4. Don’t Attempt Servicing Without Proper Training

This tip may seem like a no-brainer, but it isn’t uncommon for companies and organizations to delegate inverter maintenance to workers who have a good understanding of electrical equipment but not special training in servicing inverters. Specialized training makes maintenance more efficient, helps prevent equipment damage, and helps prevent injuries.

Need Additional Technical Support?

Like other types of electricity conduction equipment, sine wave inverters may need to be serviced while they are energized instead of powered off. When this is the case, it’s crucial to take the measures above in order to avoid physical injury and prevent equipment damage.
