connection of power cables (figures 10 to 14)

Make sure the unit is powered down and disconnected from all input power before making connections to the terminal blocks at the front or back of the cubicle (depending on the type of Comet).

For protection of life and property, earth wires should always be connected first.

For Comet 31 series or Comet 33 series devices, the Mains power supply must be with a neutral cable.

For Comet 33 series, the neutral may be reconstituted by a complete insulation transformer option (a transformer with a triple-point structure).

Neutral system: identical upstream and downstream neutral systems (no galvanic isolation). Comet can be used with all types of neutral systems, on the condition that standard practices be respected.

■check that AC input power circuit breaker, installed upstream on the low voltage switchboard, is in off (O) position;

■check that the input power switch 1 and the battery circuit breaker 4 are in off (O) position.

Connection sequence for 5 kVA Comet:

■open the protective cover 44 (secured by 2 screws) and the connection cover panel 13 (secured by 6 screws);

■strip the duct of the AC input power and load cables over a length of 7 cm;

■strip each wire over a length of 1 cm;

■insert the cables of the AC input power and load through the bushings of the connection cover panel;

■connect the cables of the AC input power to "Mains 1" XR1 terminal block in the order shown on the label;

■connect the load cables to the "load" XR2 terminal block in the order shown on the label;

■connect the various options as shown in the relevant section for each one in this manual;

■when the cables have been connected, the duct of each cable must be tightened by a binding band against the horizontal binding bar placed beneath the terminal block in order to protect the conductors from tensile loads;

■put back the connection cover panel 13 and the protective cover 44 .

Comet TM 5 - 30 kVA specifications

MGE UPS Systems Comet TM 5 - 30 kVA is a reliable and efficient uninterruptible power supply (UPS) designed to ensure the smooth operation of critical systems in various applications. This UPS is particularly suited for data centers, telecommunications, and industrial environments that require high availability and robust power protection.

One of the main features of the Comet TM series is its modular design, which allows users to scale the UPS capacity as needed. This flexibility is crucial for businesses that anticipate growth or fluctuating power requirements. The UPS is available in a range of capacities, from 5 kVA to 30 kVA, allowing for tailored solutions that fit specific power needs.

The Comet TM is equipped with advanced double conversion technology, which provides clean and reliable power, isolating the connected equipment from input voltage disturbances. This technology ensures that any fluctuations in the mains supply, such as voltage sags or surges, do not affect the operation of sensitive electronic devices. Additionally, this UPS features a wide input voltage range that contributes to improved efficiency and reduced energy consumption.

An impressive aspect of the Comet TM is its high-efficiency mode, which optimizes energy consumption while maintaining power quality. This mode reduces operating costs and contributes to lower carbon footprints, making it an environmentally friendly choice. Furthermore, the UPS incorporates intelligent battery management systems, which enhance battery performance and extend their lifespan. This is essential in minimizing downtime and ensuring that backup power is readily available when needed.

The user-friendly interface of the Comet TM allows for easy monitoring and management of the system. With graphical displays and comprehensive alarms, users can promptly identify potential issues and take corrective actions. Remote management capabilities are also built into the system, enabling users to monitor and control the UPS remotely, which is particularly beneficial for businesses that operate across multiple locations.

In summary, the MGE UPS Systems Comet TM 5 - 30 kVA is designed for organizations that need reliable power protection and high efficiency. With its modular scalability, advanced double conversion technology, high-efficiency mode, intelligent battery management, and user-friendly interface, the Comet TM series stands out as a robust solution for critical power applications. Its combination of features ensures that businesses can maintain uninterrupted operations while benefiting from cost savings and a reduced environmental impact.
