8.3Control Buttons

The Control Buttons on the front panel may be used to shut down the UPS completely, turn the inverter On or Off, restart the UPS after a fault and silence the alarm, as shown in Figure 42. The function of each button is described in Table 16.

NOTE

To activate a button properly, press and hold until you hear a short beep—about two seconds.

Completely shuts down the UPS, including the static switch.

EPO

CAUTION: Use caution before pressing the Emergency Power Off (EPO) button. This button

 

completely shuts down the unit and cuts off power to the critical load.

Inverter Off

Press this button to shut down the inverter during operation. The load will be transferred to

static bypass.

 

Fault Clear

After the UPS shuts down due to a fault and the alarm condition has been resolved, press

this button to clear the fault and restart the UPS.

 

 

Press this button once to silence the alarm buzzer when an alarm is active. Any new fault will

sound the buzzer again.

 

If the alarm buzzer is not beeping, press this button to test the alarm sound.

Inverter On

Press this button to start the inverter and transfer from static bypass to inverter.

NOTE: If the inverter is not ready, this will not activate the UPS.

480V specifications

The Emerson 480V power systems play a critical role in modern industrial applications, providing reliable and efficient power distribution. These systems are designed for facilities that require robust performance and operational efficiency while adhering to safety regulations. With voltage ratings at 480V, they cater primarily to industries such as manufacturing, data centers, and commercial buildings.

One of the main features of the Emerson 480V systems is their scalability. These systems can be easily adapted and expanded as operational demands grow, thereby reducing initial investment costs and providing a flexible solution for evolving business needs. This ability to scale is crucial in a fast-paced environment where demands can change rapidly.

The Emerson 480V systems also incorporate advanced technologies for improved performance and safety. One key technology is the use of smart grid solutions. This enables real-time monitoring, diagnostics, and control, allowing facility managers to optimize energy consumption and reduce operational costs. Furthermore, these systems often include integrated protection devices that enhance safety measures by minimizing the risk of electrical faults, overloads, or short circuits.

Energy efficiency is another characteristic that distinguishes Emerson 480V systems from traditional alternatives. With advanced power management features, these systems effectively reduce energy waste and lower electricity bills. Emerson’s commitment to sustainability is evident in its designs, which aim to minimize environmental impact through energy-efficient technologies.

The build quality of Emerson 480V systems is also noteworthy. They are designed to withstand harsh industrial environments and are constructed with high-grade materials that promote longevity and reliability. The modular design allows for easy maintenance and repair, which further extends the lifespan of the system.

Additionally, Emerson 480V systems are equipped with user-friendly interfaces that facilitate ease of operation. This ensures that operators can efficiently manage and control power distribution without extensive training. The combination of performance, scalability, safety features, and user-centric design makes Emerson 480V systems an ideal choice for businesses looking to enhance their electrical infrastructure.

In summary, Emerson 480V power systems are a leading solution for industrial power distribution, characterized by their scalability, smart technology integration, energy efficiency, robust build quality, and user-friendly operation. These attributes make them a valuable investment for any organization aiming to improve its electrical management and operational performance.
