Chapter 1 Introduction

The Powerware®9155 is a double-conversion, split-phase, online uninterruptible power system (UPS) for protecting computer systems and other intelligent devices. It is ideal for protecting essential information technology and electrical engineering infrastructure in corporate, telecom, health care, banking, and industrial applications.

The UPS provides a steady, well-regulated power supply for your computing and communications equipment, while protecting it from the frequent irregularities that are inherent in commercially available power. Voltage spikes, power surges, brownouts, and power failures have the potential to corrupt critical data, destroy unsaved work sessions, and in some instances, damage expensive hardware.

With the Powerware 9155, you can safely eliminate the effects of electrical line disturbances and guard the integrity of your systems and equipment. Figure 1 shows the Powerware 9155 UPS and an optional Extended Battery Module (EBM).

Figure 1. The Powerware 9155 UPS and EBM (2-High Cabinets Shown)

Powerware®9155 UPS (8–15 kVA) User’s Guide S 164201553 Rev D www.powerware.com

Introduction

Providing outstanding performance and reliability, the Powerware 9155’s unique benefits including the following:

쑺 OnlineUPSdesignwithpuresinewaveoutput.TheUPSfiltersand

regulates incoming AC power and provides consistent power to your equipment without draining the battery.

쑺 More wattage in less space with a 0.9 power factor – protecting more

equipment and leaving more room for expansion.

쑺 Support for Powerware Hot Synct paralleling of multiple modules for

redundancy or extra capacity.

쑺 Input current total harmonic distortion (THD) of less than five

percent, using active input power factor correction.

쑺 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.

쑺 Up to four hours of extended runtime with added EBMs. 쑺 Advanced power management with the Powerware Software Suite CD

for graceful shutdowns and power monitoring.

쑺 Emergency shutdown control through the Remote Emergency

Power-off (REPO) port.

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

power is not available.

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

contacts, and programmable signal inputs.

쑺 Optional X-Slott cards enhance communication capabilities for

increased power protection and control.

쑺 Backed by worldwide agency approvals.

Powerware®9155 UPS (8–15 kVA) User’s Guide S 164201553 Rev D www.powerware.com

Introduction

The following options for the Powerware 9155 are available:

쑺 Maintenance Bypass Module (MBM)

The optional MBM is installed on the UPS rear panel and is used to bypass the UPS during maintenance or servicing. The Maintenance Bypass switch on the MBM provides a Make-Before-Break (MBB) wrap-around bypass for UPS service without shutting down the load.

쑺 Power Distribution Module (PDM)

The optional PDM provides the same functionality as the MBM and also comes equipped with several different types of output receptacles.

쑺 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.

쑺 Parallel Tie Cabinet

A parallel system with up to three 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 t o the critical load. A parallel Powerware Hot Sync Computer Area Network (CAN) Bridge Card provides connectivity for system metering and o perational mode control. The parallel system consists of two to three UPSs, each with a parallel CAN Bridge Card, and a parallel t ie cabinet. Refer to the Powerware 9155 Parallel UPS (8–15 kVA) User’s Guide for more information.

쑺 Input Isolation Transformer

The optional input isolation transformer is located at the bottom of a 3-high UPS model. The input isolation transformer provides a neutral from a 208V or 240V input source with 240V output and can be wired to the UPS or to an MBM/PDM.

쑺 Seismic Kit

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

UPS Only Installation

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 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 and wire sizes to the ones in the following wiring table:

Table 1. Circuit Breaker Ratings

UPS Capacity Input Circuit Breaker Rating Minimum Wire Size*

8kVA 60A 4AWG(21.2mm2)

10 kVA 80A 3AWG(26.7mm2)

12 kVA 100A 2AWG(33.6mm2)

15 kVA 100A 2AWG(33.6mm2)

*Use only 90°C-rated c opper 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.

NOTE To accommodate the feature of easy system expandability, it is

recommended that initial installation of the Powerware 9155 UPS contain wiring to support the maximum capacity of the UPS cabinet.

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.

5. Verify that the UPS battery circuit breaker is in the OFF position

(see Figure 5).

rectifier/bypass input

쑺 2-phase (L1 and L2), neutral, and ground connection for load output

CAUTION

쑺 The input isolation transformer output is always 240V (180° phase angle). 쑺 If installing an MBM/PDM, the UPS MUST be set up for 240V output only;

otherwise, the “Bypass Not Available” alarm annunciates. Any equipment connected to the output requiring 208V (120° phase angle) is at risk for damage when using the Maintenance Bypass switch.

쑺 The input isolation transformer cannot be used with a wall-mounted bypass

switch.

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

Figure 11 and Figure 12 beginning on page 27 show the oneline diagrams of the input isolation transformer with the UPS.
