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).

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.

Chapter 5 Wall-Mounted Bypass Switch Installation

This chapter describes installing the wall-mounted bypass switch with
the UPS. The wall-mounted bypass switch is a Make-Before-Break
maintenance bypass switch.

NOTE The input isolation transformer cannot be used with the wall-mounted bypass
switch.

The Powerware 9355 has the following power connections:

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

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

WARNING

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

Use the following procedure to hardwire the bypass cabinet:

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 2 on
page 33.

3. Switch off utility power to the distribution point where the bypass

cabinet and UPS will be connected. Be absolutely sure there is no
power.

Remote Emergency Power-off

REPO is used to shut down the UPS from a distance. This feature can
be used for shutting down the load and the UPS by thermal relay, for
instance in the event of room overtemperature. When REPO is
activated, the UPS shuts down all converters, de-energizes all system
relays, and fully powers down within 10-15 seconds.

There are two REPO positions that may be used, normally-open or
normally-closed.

The pins on the normally-closed REPO connector are connected
together. When this connection is open, the logic circuitry completely
shuts down the UPS, thus preventing the power from supplying the
load.

If the use of normally-closed REPO operation is desired, replace the
connector with a normally-closed external switch (see Figure 33 on
page 47).

If the use of normally-open REPO operation is desired, connect a
normally-open external switch (see Figure 33 on page 47).

NOTE To restart the UPS, reconnect the REPO connector pins and turn on the UPS
manually. The pins must be shorted to keep the UPS running. Maximum resistance is 10 ohm.

NOTE Leave the REPO connector installed in the REPO port on the UPS rear panel even if
the REPO function is not needed.

CAUTION

The REPO must not be connected to any utility connected circuits. Reinforced insulation to
the utility is required. The REPO switch must have a minimum rating of 24 Vdc and 20 mA.

To ensure the UPS stops supplying power to the load during any mode of operation, the
input power must be disconnected from the UPS when the emergency power-off function is
activated.

Relay Output Contacts

The UPS incorporates a programmable relay output with potential free
contacts for remote alarm indications (see Figure 33 on page 47). An
additional four relay outputs can be obtained with the X-Slot compatible
Relay Interface Card.

WARNING

The relay contacts must not be connected to any utility connected circuits. Reinforced
insulation to the utility is required. The relay contacts must have a maximum rating of
30 Vdc/1A and 60 Vdc/2A nominal values.

Programmable Signal Inputs

The UPS incorporates two programmable signal inputs (see Figure 33 on
page 47). Use of non-polar (relay) control input is recommended. The
pins must be shorted with maximum resistance of 10 ohm in order to
activate the specific input.

NOTE See Figure 44 on page 60 for the polarity and verify these connections if polarity
control is required.

Chapter 10 UPS Maintenance

This section explains how to:

S Care for the UPS and batteries

S Recycle used batteries

S Use the maintenance bypass switch

UPS and Battery Care

For the best preventive maintenance, keep the area around the UPS
clean and dust-free. If the atmosphere is very dusty, clean the outside of
the system with a vacuum cleaner.

For full battery life, keep the UPS at an ambient temperature of
77°F(25°C).

NOTE The batteries in the UPS are rated for a 3–5 year service life. The length of
service life varies, depending on the frequency of usage and ambient temperature.
Batteries used beyond expected service life will often have severely reduced runtimes.
Replace batteries at least every 5 years to keep units running at peak efficiency.

Storing the UPS and Batteries

When storing the UPS and optional cabinets, the following requirements
should be met:

S Verify that the battery circuit breaker is in the OFF position.

S Avoid temperature and humidity extremes. To maximize battery life,

the recommended storage temperature is 59°F(15°C) to 77°F(25°C).

S If you store the UPS for a long period, recharge the batteries every

10 months by applying utility power. The batteries charge to 80%
capacity in approximately 3 hours. However, it is recommended that
the batteries charge for 48 hours after long-term storage.

S Check the battery recharge date on the shipping carton label. If the

date has expired and the batteries were never recharged, do not use
the UPS. Contact your service representative.

UPS MAINTENANCE

When to Replace Batteries

When the indicator flashes and the LCD panel displays Battery
Failure, the batteries may need replacing. Contact your service
representative to order new batteries.

Change the batteries approximately every five years.

Recycling the Used Battery or UPS

Contact your local recycling or hazardous waste center for information
on proper disposal of the used battery or UPS.

S Do not dispose of the battery or batteries in a fire. Batteries may explode. Proper

disposal of batteries is required. Refer to your local codes for disposal requirements.

S Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the

skin and eyes. It may be toxic.

Do not discard the UPS or the UPS batteries in the trash. This product contains sealed,
lead-acid batteries and must be disposed of properly. For more information, contact your
local recycling/reuse or hazardous waste center.

Using the UPS Maintenance Bypass Switch

The UPS maintenance bypass switch is located on the back of the UPS
(see Figure 46).

The maintenance bypass switch is used to bypass the UPS during
maintenance or servicing. The switch provides a wrap-around bypass
without shutting down the load. The SERVICE position on the switch
allows a service engineer to apply power to the UPS input and verify its
operation while the load is powered through bypass.

UPS MAINTENANCE

To switch the UPS to maintenance bypass from Normal mode:

1. Turn the maintenance bypass switch through the SERVICE position

to the BYPASS position.

The battery circuit breaker trips, and the UPS is now bypassed, with
the load powered by utility power.

2. The UPS automatically shuts down.

To return to Normal mode from maintenance bypass:

1. Turn the maintenance bypass switch to the SERVICE position.

The UPS starts up in Bypass mode, with the load still powered by
utility power.

2. Switch the UPS battery circuit breaker to the ON position.

NOTE Wait until the indicator illuminates before proceeding to Step 3; otherwise,
power to the load may be lost.

to alert the user. Use the following troubleshooting chart to determine
the UPS alarm condition.

Typical Alarms and Conditions

The following table describes typical alarms and conditions; check the
Event Log through the control panel for a list of active alarms. If an alarm
appears with a service code, please contact the Help Desk (see
