1Use only 90°C-rated copper wire. Minimum wire size is based on 120/208 full load ratings applied to NEC Code Table 310-16. Code may require a larger AWG size than shown in this table because of temperature, number of conductors in the conduit, or long service runs. Follow local requirements.

2 Per NEC article 300-20(a), all three-phase conductors must be run in the same conduit. Neutral and ground must be run in the same conduit as the phase conductors.

3 Conduit is sized to accommodate one neutral conductor the same size as the phase conductor and one ground conductor. If two neutral conductors or an oversized neutral conductor are to be installed, check the size of the conduit needed to accommodate the extra wire or size and use that conduit size in place of the conduit size listed. Conduit sizes were chosen from NEC Table C1, type letters RHH, RHW, RHW-2, TW, THW, THHW, THW-2.

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.
