shutdown

shutdown of the inverter

press the "inverter OFF" button 8 on the control panel for three seconds (see figure 19).

single-UPS unit

the green "inverter" light 4 on the con- trol panel goes off;

the green "static-bypass" light 3 goes on;

the inverter stops;

if bypass AC source (Mains 2) transfer conditions are satisfied, the inverter shuts down and the load is transferred to the bypass AC source;

if bypass AC source (Mains 2) transfer conditions are not satisfied, the inverter does not shut down. The message

"MAINS 2 OUTSIDE TOLERANCES, TRANSFER DISABLED" is displayed.

parallel UPS unit

if the system is redundant, i.e. the other parallel-connected inverters can supply the load on their own, the inverter shuts down and the green "inverter" light 4 goes off.

The load is not affected in that the other inverters continue to supply it normally;

if the system is not redundant, the other inverters go to overload status.

If overload conditions are overrun, the load is transferred to the bypass AC source:

the green lights 3 turn green,

the green "inverter" light 4 goes off.

shutdown of a rectifier/charger

It is recommended not to stop the rectifi- er/charger because the battery will no longer be charged. Except in the case of a test of the inverter on battery power, the rectifier/charger should be shutdown after the inverter to avoid unnecessary battery discharge.

Proceed in the following order:

open battery circuit breaker QF1;

open normal AC input circuit breaker Q1:

the rectifier/charger shuts down,

the green "rectifier/charger" light 1 goes off.

This is particularly essential for sensitive electronics that require a consistent power supply to function correctly.

Another significant characteristic of the Galaxy PW is its energy efficiency. The UPS is designed to operate at high efficiency levels, often exceeding 96%. This not only helps in reducing the overall energy consumption but also lowers operational costs and reduces the carbon footprint of the facility. The Eco-Mode feature allows the UPS to deliver power with minimal energy loss during normal operating conditions.

The Galaxy PW is equipped with advanced communication and management features, including an intuitive graphical LCD display that provides real-time information on the system's status and performance metrics. Users can monitor input and output voltages, current load levels, and battery health at a glance. Additionally, the UPS supports various communication protocols and interfaces, facilitating integration with building management systems and remote monitoring tools.

Safety and reliability are also top priorities for the Galaxy PW. The system features robust battery management to extend the lifespan of the batteries while ensuring optimal performance. The UPS is designed with several protections, including overload, short-circuit, and thermal protection, to safeguard both the UPS and connected loads.

In summary, the MGE UPS Systems Galaxy PW integrates modularity, energy efficiency, advanced monitoring, and robust protection features to deliver unmatched reliability for critical power applications. Its innovative design and technologies make it an ideal choice for businesses seeking a reliable power protection solution.
