FAQ

What is a UPS?

A UPS provides protection of your critical load or infrastructure. The UPS protects this load from spikes, surges, voltage transients, power outage, frequency variation and include voltage regulation for your critical equipment.

What does a UPS do for me?

Do you have constant outages or bad power quality? A UPS will assist with all of these issues to keep you running along with the peace of mind that you are protected.

What do UPS Systems protect against?

Depending on the system the UPS will protect against any of the following 9 power problems:

  • Power Failure
  • Power Sag
  • Power Surge
  • Under Voltage
  • Over Voltage
  • Line Noise
  • Frequency Variation
  • Switching Transient
  • Harmonic Distortion

What size UPS do I need?

This is dependent on your load and industrial equipment. For example, small motors may require a larger UPS due to start-up requirements. A slightly larger system than your current load is suggested to allow for load growth, spikes, surges or other events.

What type of UPS do I need?

Every situation is different for different reasons. EPT supplies the equipment you need rather than from any particular brand which means that we can assist to get you the right UPS for your situation.

My business is small, do I really need a UPS?

How well can your business cope without power? If a server or network switch/router is taken offline by a power surge or spike, how long will it take your business to recover? In today’s age where nearly all businesses are connected, online power protection and backup is increasingly relevant. The question is, can you run your business without a UPS?

Why is my UPS beeping or alarming?

Most UPS systems have 3 main reasons for beeping and alarming:

  • The system is running on batteries
  • The UPS requires new batteries
  • The unit has failed and requires service or repair

How often do I need to replace my UPS and UPS Batteries?

Providing the correct maintenance requirements have been met, UPS systems have a general life span of up to 15 years.

Batteries depending on size require either 3-5 year replacement or 7-10 year replacement.

Systems maintained by EPT will be notified when batteries are due to be replaced, enabling customers to reduce costs of overall labour and supply times.

How long does a UPS last in a power outage?

Most UPS systems are designed for around 10-15 minutes runtime on battery autonomy at full load. Additional battery packs can be added to most UPS systems. Depending on make and model will depend on number of battery packs available. With the correct systems, almost unlimited run times are available.

Do I need ongoing maintenance on my UPS?

UPS units are the first line of protection for your critical equipment. They continuously battle with incoming surges and regulate the output power.

Environmental factors, temperature, dust and debris can affect the life expectancy and performance of the internal components. Therefore, it is important to have an ongoing maintenance plan for your UPS.

How often a UPS requires maintenance will be determined by a number of the above factors. Contact the team at EPT to discuss the option of having manufacturer trained UPS specialists assist you with the maintenance of your business-critical infrastructure.

How do I get the most out of my UPS?

Environmental issues are the greatest factor that compromise the workings of a UPS.

Maintaining system temperatures is critical for battery life as high temperatures will significantly reduce the life of the system. Regular maintenance will provide trends on battery functionality, condition and backup time. This maintenance will also ensure you get the most out of your system over its lifetime.

What happens if my UPS fails?

EPT can have a technician sent to site, or discuss options to bring smaller UPS systems to our workshop. Our factory trained technicians will conduct full testing and repairs to manufacturer specifications.

Can I access my UPS remotely over a network?

Most UPS systems have network card availability to allow monitoring across a network. This includes options like server shutdown, email notification etc. To ensure you are getting the communications you require, contact our specialist team to assist you with all available options.

Can I install my UPS?

Small Plug in UPS systems can be installed by the user easily in most instances.

Larger hard-wired systems will require installation by an electrical contractor, to ensure the installation is safe and to the relevant standards, and a manufacturer trained and competent UPS technician to commission.

EPT is an electrical contractor and authorised service agent for multiple manufacturers. We can perform the supply/installation/commissioning and ongoing maintenance in-house to provide you with peace of mind the unit is installed correctly to relevant standards, ensuring there are no safety concerns.

Do I need a Surge Protector with a UPS?

Whilst a UPS does protect against power surges, depending on location a surge protector is still advisable to deal with large impact surges. i.e. lightning strike

Is power quality really an issue today?

Power Quality issues are more relevant today due to our computing and online systems requiring better quality power. Businesses relying on power for their critical IT infrastructure require near perfect power quality

Do I need a UPS if I have a generator?

A generator does not protect against all power problems, and isn’t an instant supply of power. If your business needs continuous power, a UPS is required to bridge the gap between mains and generator.

Is there any risk in lack of battery maintenance?

Lack of battery maintenance can cause many problems including load loss, fire or property damage. Regular maintenance of batteries is suggested to get the longest lifecycle out of your equipment.

I have one failed battery in my UPS, can I replace just the one?

Depending on environmental conditions and age, it may be possible to replace a single UPS battery. However, the system as a whole must be tested to ensure other cells are not failing. It is very important if replacing single batteries that it is replaced with same type/brand/age/impedance as those in the battery string to avoid further failures of other batteries. It is best to contact EPT to discuss options, replacement and maintenance.
