Eaton Powerware PW9355, 15000VA Tower UPS

The Eaton Powerware PW9355 15000VA Tower UPS is engineered to shield critical IT infrastructure from the harsh realities of power disturbances. With a formidable 15,000 VA capacity and a 13-minute runtime at full load, this tower-style uninterruptible power supply delivers dependable, datasheet-class protection for servers, storage, networking gear, and edge deployments. Designed for data centers, server rooms, and distributed IT environments, the PW9355 combines robust power conditioning, reliable battery support, and intelligent management to keep workloads online during outages, sags, and transient spikes. Its space-efficient tower form factor makes it a practical solution when floor space is at a premium, while its scalable runtime and straightforward maintenance help IT teams minimize downtime and maximize uptime.

• High-capacity protection for mission-critical IT: The PW9355 delivers an expansive 15000 VA capacity, enabling you to support multiple servers, virtualization hosts, storage arrays, and essential networking equipment from a single, centralized UPS. This level of capacity absorbs load surges and buffers protective margins to maintain stable operation during power events, reducing the risk of unexpected shutdowns and data loss.
• 13 minutes of full-load runtime: A standout feature is the uptime it provides at full load, giving IT staff ample time to gracefully shut down systems or migrate workloads to alternate power supplies. This extended runtime is especially valuable during utility outages, allowing clean, controlled system maintenance and safeguarding critical processes from abrupt interruption.
• Tower design for space-efficient data centers and edge locations: The PW9355’s tower form factor is purpose-built for environments where cabinet space is limited. It offers a stable, freestanding profile that sits securely on the floor or alongside equipment racks, simplifying installation in data centers, server rooms, and remote office locations while reducing footprint without compromising protection.
• Advanced power conditioning and protection: The PW9355 protects connected equipment from voltage sags, surges, and waveform irregularities through sophisticated conditioning and regulation. This ensures clean, steady output even when incoming power fluctuates, helping to preserve hardware longevity and deliver consistent performance for mission-critical workloads.
• Comprehensive management and monitoring: Designed with enterprise-grade management in mind, the PW9355 integrates with standard UPS management interfaces and software. This enables remote monitoring, alerting, event logging, and controlled shutdowns, making it easier to supervise power reliability across multiple devices and locations from a single pane of glass.

How to install Eaton PW9355 15000VA Tower UPS

• Choose an installation location: Select a well-ventilated, level surface with adequate clearance for maintenance access, airflow, and ventilation. Avoid damp or dusty areas, and keep the unit away from direct heat sources or clutter that obstructs airflow.
• Prepare the space and power source: Confirm the local electrical supply meets the UPS’s input requirements and is compatible with your facility’s electrical codes. Ensure the floor is solid and can bear the weight of the UPS and any connected equipment.
• Position and secure the UPS: Place the PW9355 in its chosen location, ensuring stability. If mounting is required or recommended by the manufacturer, follow the installation guidance to secure the unit and prevent movement during operation or maintenance.
• Connect the battery and power components: Attach any battery modules or backup components according to the user manual, ensuring proper polarity and secure connections. Allow the battery system to initialize with a controlled charge before connecting critical loads.
• Connect output loads: Plug critical servers, storage devices, and networking gear into the UPS’s output outlets. Avoid overloading outlets; distribute load across multiple outlets if the unit supports it, maintaining a safe margin below rated capacity.
• Connect input power and grounding: Connect the UPS to the main electrical supply with an appropriate cord or feeder. Ground the unit per electrical code requirements to provide a reliable fault path and protect personnel and equipment.
• Set up management interfaces: Attach any network management cards, USB, or serial interfaces as applicable. Install compatible management software on a connected computer or server to monitor voltage, load, battery health, and runtime.
• Configure alerts and testing: Define alarm thresholds, notification methods (email, SNMP, or local alerts), and perform an initial functional test. Run a simulated outage to verify automatic shutdown procedures and graceful handoffs to backup power.
• Schedule regular maintenance: Establish a routine for battery health checks, firmware updates, and periodic runtime tests to ensure ongoing reliability and to extend the life of the UPS and its batteries.
