Chapter 1 Introduction

The Powerware®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.

The Powerware 9355 UPS continually monitors incoming electrical
power and removes the surges, spikes, sags, and other irregularities
that are inherent in commercial utility power. Working with a building’s
electrical system, the UPS supplies clean, consistent power that
sensitive electronic equipment requires for reliable operation. During
brownouts, blackouts, and other power interruptions, batteries provide
emergency power to safeguard operation.

With the Powerware 9355 UPS, you can safely eliminate the effects of
electrical line disturbances and guard the integrity of your systems and
equipment. Figure 1 shows the Powerware 9355 UPS and an optional
Extended Battery Module (EBM).

Figure 1. The Powerware 9355 UPS and EBM (3-High Cabinets Shown)

INTRODUCTION

Providing outstanding performance and reliability, the Powerware 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.

S A UPS maintenance bypass switch provides a Make-Before-Break

(MBB) wrap-around bypass for UPS maintenance or service without
shutting down the load.

S Support for Powerware Hot Sync

®

paralleling of multiple modules for

redundancy or extra capacity.

S Input current total harmonic distortion (THD) of less than five percent,

using active input power factor correction.

S ABM

®

technology that uses advanced battery management to
increase battery service life, optimize recharge time, and provide a
warning before the end of useful battery life.

S Up to three hours of extended runtime with added EBMs.

S Advanced power management with the Software Suite CD for

graceful shutdowns and power monitoring.

S Emergency shutdown control through the Remote Emergency

Power-off (REPO) port.

S Start-on-battery capability for powering up the UPS even if utility

power is not available.

S Standard communication options with a DB-9 serial port, relay output

contacts, and programmable signal inputs.

S Optional X-Slott cards enhance communication capabilities for

increased power protection and control.

INTRODUCTION

The following options for the Powerware 9355 are available:

S Remote Monitor Panel (RMP)

The optional RMP provides monitoring of the operational status and
alarm condition of the UPS from virtually any location within the
facility. You can install multiple RMPs at remote locations to increase
your monitoring capabilities.

S Power Distribution Module (PDM)

The optional PDM comes equipped with several different types of
output receptacles.

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. In addition, when
one UPS is taken out of service for maintenance or is not operating
properly, a redundant UPS continues to supply uninterrupted power
to the critical load. A parallel Powerware Hot Sync Computer Area
Network (CAN) Bridge Card provides connectivity for system
metering and operational mode control. The parallel system consists
of two to four UPSs, each with a parallel

CAN Bridge Card, and a parallel

tie cabinet. Refer to the Powerware 9355 Parallel UPS (10/15 kVA)
User’s Guide for more information.

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 Input Isolation Transformer

The optional input isolation transformer is located at the bottom of a
3-high UPS model. The isolation transformer allows operation from a
480V or 600V 60-Hz source.

S Seismic Kit

The optional seismic kit secures the UPS and optional EBMs for
Zone 4 seismic installations.

S 3-phase (L1, L2, and L3), neutral, and ground connection for

rectifier/bypass input

S 3-phase (L1, L2, and L3), neutral, and ground connection for load

output

The nominal input/output voltages are:

S 120/208 or 127/220 Vac with 120° phase displacement

S 480V or 600V 60-Hz input is available using the optional input isolation

transformer module

Output overcurrent protection and disconnect switch must be provided
by others.

Figure 15 through Figure 17 beginning on page 25 show the oneline
diagrams.

Only qualified service personnel (such as a licensed electrician) should perform the UPS
installation and initial startup. Risk of electrical shock.

WARNING

Use the following procedure to hardwire the UPS:

1. Verify that the electrical connections to the installation site have

been properly installed.

2. A wall-mounted, user-supplied, readily-accessible disconnection

device must be incorporated in the input wiring.

Compare the circuit breaker ratings to the ones in Table 1 on
page 22.

3. Switch off utility power to the distribution point where the UPS will

be connected. Be absolutely sure there is no power.

4. Determine your equipment’s grounding requirements according to

your local electrical code.

Conduit is sized to accommodate one neutral conductor the same size as the phase conductor and one #8 AWG
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.
