TIE CABINET INSTALLATION

22.Wire the maintenance bypass auxiliary contacts and terminate to the maintenance bypass wires in the Tie Cabinet (see Figure 6 on page 12).

Connect the black and the red wire to TB4 on the UPS (see Figure 9). Cap the blue wire.

NOTE The maintenance bypass contacts are normally-open. To ensure proper bypass operation, DO NOT use the blue wire (it is normally-closed).

NOTE There are two sets of maintenance bypass wires; you can terminate to either set. If you are installing four UPSs, it is recommended to terminate two UPSs to one set of wires and two UPSs to the other set of wires.

Powerware 9355 specifications

The Powerware 9355 is an uninterruptible power supply (UPS) designed to provide continuous and reliable power protection for critical systems in various environments, including data centers, telecommunications, and industrial applications. This UPS model is renowned for its robust features, advanced technologies, and remarkable characteristics, making it a preferred choice for businesses requiring uninterrupted power supply.

One of the standout features of the Powerware 9355 is its double-conversion architecture. This technology ensures that the output power is continually conditioned and isolated from the input power fluctuations. By converting incoming AC power to DC and then back to AC, the UPS effectively eliminates any disturbances, providing clean and stable power to sensitive equipment. This is particularly critical in environments where even brief power interruptions can lead to data loss or system failures.

The Powerware 9355 is designed with a modular and scalable architecture, allowing organizations to customize their power solutions based on current and future needs. This flexibility enables users to start with a lower capacity and expand by adding additional units or redundancy, ensuring that the system can grow in line with the organization’s increasing power demands.

Efficiency is another key characteristic of the Powerware 9355. With its high-efficiency operation, the UPS minimizes energy consumption, resulting in reduced operational costs and a smaller carbon footprint. Many models include energy-saving features such as an eco-mode, which allows the UPS to operate in a more efficient state during certain conditions while still providing the necessary power protection.

The Powerware 9355 also offers user-friendly management features, including an interactive LCD interface that provides real-time data on the UPS status, including input and output voltages, frequency, load percentage, and battery health. Additionally, remote monitoring capabilities allow users to manage and monitor their UPS systems from anywhere, enhancing operational efficiency and power management.

Durability and reliability are fundamental to the design of the Powerware 9355. It is built with high-quality components that enhance its lifespan and performance, ensuring that users have a dependable source of power during critical moments. With a strong focus on redundancy, the UPS includes features such as hot-swappable batteries, reducing downtime during maintenance.

In conclusion, the Powerware 9355 stands out as a high-performance, versatile UPS solution that integrates advanced technologies, efficiency, and user-centric features. Its double-conversion architecture, modularity, high efficiency, and robust management capabilities make it an ideal choice for organizations looking to ensure continuity and reliability in their power supply.
