Chapter 1 Introduction The Eaton® 9355 uninterruptible power supply (UPS) is a true online, double-conversion, three-phase system that can be used to prevent loss of valuable electronic information and minimize equipment downtime. It is ideal for protecting essential information technology and electrical engineering infrastructure in corporate, telecom, health care, banking, and industrial applications.
INTRODUCTION Providing outstanding performance and reliability, the Eaton 9355 UPS's unique benefits including the following: S Online UPS design with pure sine wave output. The UPS filters and regulates incoming AC power and provides consistent power to your equipment without draining the battery. S More wattage in less space with a 0.9 power factor — protecting more equipment and leaving more room for expansion.
INTRODUCTION S Wall-Mounted Bypass Switch The optional wall-mounted bypass switch is used to bypass the UPS during maintenance or servicing, providing wrap-around bypass for UPS service without shutting down the load. S Parallel Tie Cabinet An optional parallel system with up to four UPSs can be installed to provide a parallel capacity and/or redundant system. This load sharing system provides more capacity than a single UPS and can provide backup, depending on the load and configuration.

To access and install the communication options and control terminals: 1. Remove the UPS front door (see page 10). 2. Install the appropriate X-Slot card and/or necessary cables into the ports (see Figure 36 and Figure 37). 3. Route the control terminal cable(s) through the middle of the fan section and secure in the cable clips.
COMMUNICATION 4. Route the cable(s) through the opening between the two X-Slot communication bays. Communication Opening Figure 38. Routing the Cables 5. Remove the communication wiring access plate from the UPS rear panel and punch a hole in it using a Greenlee punch or similar device (see Figure 39). Communication Wiring Access Plate Figure 39. Communication Wiring Access 6. Connect the cables to the appropriate location.
COMMUNICATION Communication Options The Eaton 9355 UPS has serial communication capabilities through the DB-9 communication port or through an X-Slot card in one of the available bays. In addition, the LanSafe Power Management Software can be installed and used to communicate with the UPS via one of the serial communication connections.
COMMUNICATION X-Slot Cards For information about the Powerware Hot Sync CAN Bridge Card, see “Parallel Communication” on page 67. X-Slot cards allow the UPS to communicate in a variety of networking environments and with different types of devices.
COMMUNICATION Remote Monitor Panel The optional RMP can be installed to monitor the operation of the UPS from virtually any location within your facility, up to 500 ft (152.4m) from the UPS. You can surface‐mount an RMP on a desktop or on a wall, wherever you have a serial interface line. Figure 42 shows an RMP. Figure 43 shows the enclosure dimensions and cable exit openings.
