INTRODUCTION

The Powerware 9170 uninterruptible power system (UPS) is a modular UPS that contains battery modules and power control modules (referred to as power modules). These modules plug into a rack cabinet structure containing additional control, communication, and display functions that enable integrated control of all power modules. The UPS is housed in a single cabinet, with extra battery capacity housed in auxiliary battery cabinets.

The pluggable power modules can be removed and replaced (hot-swapped) without powering the UPS down if the UPS has sufficient redundant capacity. Battery modules may also be hot-swapped for maintenance. Power control circuitry in the cabinet senses problems in power modules, and automatically transfers control and load to the remaining power modules.

All power modules share the load requirements equally. For example, three power modules are capable of supplying a total of 9 kVA. If a load requires only 4.5 kVA, each power module supplies 1.5 kVA to the output. If one power module is removed or for some reason fails, each of the two remaining power modules would supply half of the load, or

2.25 kVA. In other words, redundancy exists when the load can be supplied by less than all of the installed power modules.

The UPS can be configured with up to seven power modules; its output is limited such that an excess number of power modules allow the failure of one or more modules without causing the UPS to lose any functionality.

To permit UPS removal from the power path, while maintaining power to the loads, an external bypass switch is required. This switch is optional but recommended for system serviceability.

INSTALLATION SETUP

This chapter explains how to setup and install the Powerware 9170 cabinets:

 Unpacking and setup, including clearances and location requirements  Caster cart installation  Stabilizer bracket installation (for 12-slot cabinets with non-isolated

output)

 Rack-mount installation  Floor anchor kit installation  Moving the cabinets

Equipment Clearances

All cabinet sizes require the following clearances to allow for servicing and adequate ventilation:

 From the side panels: 6 (15.2 cm)  Top and back: 12 (30.5 cm)  Front: 36 (91.5 cm)

If flexible conduit connects the UPS to the service input and load distribution panels, you may be able to gain access for servicing by moving the UPS. If this is the case, you must still leave 12 (30.5 cm) clearance at the back and 6 (15.2 cm) at the sides of the UPS for ventilation.

NOTE Do not block the ventilation holes on each side and the back of the unit.

Nine- and 12-slot external battery cabinets may be installed with bases tight against the UPS cabinet base and against each other. Six-slot cabinets require 6 of separation.

Installation Setup

Location Requirements

Install the Powerware 9170 UPS as close as possible to the equipment or the load distribution panel it will protect. If this distance is more than 25 ft (7.6m), transient noise can reappear in the electrical distribution system.

If additional Powerware 9170 system batteries are in a separate cabinet, the external battery cabinet should be located as close as possible to the Powerware 9170 UPS. If the batteries will be further from the unit than the standard cables allow, contact your service representative or your local distributor for assistance.

UPS Unpacking and Setup

The Powerware 9170 UPS is shipped in a carton on a shipping pallet. Power and battery modules are shipped in separate boxes on another pallet. Three-slot cabinets and modules are shipped on one pallet.

NOTE Verify that all Powerware 9170 UPS power modules are the proper type for the UPS cabinet: Universal (single-phase) modules have white labels; split-phase modules have blue labels. Do not mix blue and white modules in the same UPS cabinet.

To open the UPS carton and remove the UPS from its shipping pallet, use one of the following procedures. Also refer to the unpacking instruction sheet (LTS-1724) packed inside the UPS shipping carton.

Three- and Six-Slot Cabinets

1. Open the top of the carton by cutting the banding straps that hold the carton to the pallet. Open the carton flaps or lift the cover off.

2. Remove any packing material inside the carton. Also remove the cartons from the cabinet module slots containing front panel bezels, electrical or mechanical hardware, and printed material.

3. Two people are required to lift the cabinet; one to lift the two front straps and one to lift the two rear straps.

NOTE Do not attempt to lift the cabinet by the module shelves or other convenient edges or panels.

Powerware® 9170 User's Guide  LTM-1344 B Uncontrolled Copy

Installation Setup

4. If an optional caster cart is included for cabinet mobility, see Caster Cart Installation" on page 10 for information about mounting the cabinet on the cart and stabilizing it using the cart foot pads.

5. After placing the cabinet in its intended operating location, cut the lifting straps or slip them off the cabinet base tabs.

6. If you are installing an external battery cabinet, continue to Battery Cabinet Installation" on page 17.

If you do not have an external battery cabinet, continue to UPS Startup" on page 49 for plug-receptacle units or to Electrical Installation" on page 23 for hardwired units.

Nine- and Twelve-Slot Cabinets

NOTE The 12-slot Powerware 9170 UPS cabinet with non-isolated output is shipped

with two stabilizer brackets. These brackets must be attached to the wall or the floor behind the UPS cabinet (see page 11).

1. Open the top of the carton by cutting the straps that hold the cover to the carton. Lift the cover off.

2. Remove the pallet ramp packed on top of the cabinet. Locate the ramp-mounting hardware (supplied in the accessory kit) and attach the ramp to the pallet as shown in LTS-1724, accompanying the hardware.

3. Remove any packing material inside the carton. Also remove cartons containing front panel bezels, electrical or mechanical hardware, and printed material.

4. Lower the four cabinet casters (one at each corner of the cabinet base) by using a 1/2 hex-style socket wrench to turn each bolt clockwise.

5. With all casters fully extended, carefully roll the cabinet down the ramp and to its intended operating location.

6. To stabilize the cabinet in its operating location, turn the four caster bolts counter-clockwise until the cabinet rests on the floor. Place a plastic cap into each bolt access hole.

Installation Setup

NOTE If the floor is uneven and the cabinet is tilted or unstable, you may need to place a thin steel plate under a corner. Do not use the caster bolts to level the

cabinet.

7. If you are installing an external battery cabinet, continue to

Caster Cart Installation

An optional caster cart (ASY-0527) is available for 3- and 6-slot cabinets for increased mobility of the UPS (see Figure 7).

NOTE The UPS cabinet is heavy. This procedure requires two people to lift and position the cabinet onto the caster cart. Lift the cabinet using four lifting straps shipped with the cabinet; do not attempt to lift the cabinet by the module shelves or other convenient edges or panels.

Battery Cabinet Installation" on page 17.

If you do not have an external battery cabinet, continue to UPS Startup" on page 49 for plug-receptacle units or to Electrical Installation" on page 23 for hardwired units.

Caster Cart

Figure 7. Three-Slot Cabinet Being Lowered onto Caster Cart

The caster cart, shipped separately from the UPS cabinet, must be placed under the cabinet before installing power and battery modules, and before plugging the UPS into the intended power outlet.

Powerware® 9170 User's Guide  LTM-1344 B Uncontrolled Copy

The cart requires no bolts or other hardware to fasten it to the UPS cabinet. It is shaped to fit securely under the cabinet, ensuring proper alignment after placing the cabinet on the cart.

Four foot pads under the cart keep the cart from rolling when it is in its intended location. Turn each threaded foot to lower it to the floor. When the foot is tight against the floor, turn the lock nut on the threaded foot up tight against the bottom of the cart to keep the foot from rotating.

If leveling of the UPS is required, use the foot pads to raise a side or corner before locking them with their lock nuts.

Stabilizer Bracket Installation

The 12-slot Powerware 9170 UPS cabinet with non-isolated output is shipped with two stabilizer brackets. These brackets must be attached to the wall or the floor behind the UPS cabinet. Under all module-loading conditions, they act as a protective stop to prevent the cabinet from falling forward if it is unintentionally pushed away from the wall.

As shown in Figure 8, each bracket has holes that enable it to be attached by screws to either the wall or the floor (or both) behind the intended cabinet installation. The brackets are not attached to the cabinet base itself. Install the brackets as follows.

1. Select the location for the brackets, approximately 1216 (3041 cm) apart, at the floor/wall intersection behind the intended cabinet location.

2. Using the proper type of customer-supplied screws for the intended mounting surface, attach each bracket as shown in Figure 8. All screws must be driven into structural material such as wall studs.

3. Roll the UPS cabinet to its intended location, positioning the rear section of the cabinet base under the open ends of the stabilizer brackets, as far as the cabinet will go.

4. Turn all four caster bolts counter-clockwise until the cabinet rests on the floor. Place a plastic cap into each bolt access hole.

Installation Setup

NOTE If the floor is uneven and the cabinet is tilted or unstable, you may need to place a thin steel plate under a corner. Do not use the caster bolts to level the

cabinet.

Moving the Cabinets

The Powerware 9170 UPS and the battery cabinet are very heavy with power and battery modules installed. Before moving the cabinets, remove the power and battery modules and move these modules separately from the cabinets.

The smaller (3- and 6-slot) cabinets may be ordered with a caster cart, to enable moving the cabinet. Caster Cart Installation" on page 10 describes how to set the four foot pads on this cart to keep the cabinet from rolling when properly positioned.

The larger (9- and 12-slot) cabinets have casters built into the cabinet base. Use the following procedure to raise the cabinet before rolling it on its casters. For 12-slot cabinets that do not have output isolation, see Stabilizer Bracket Installation" on page 11, for details about mounting stabilizer brackets before rolling the cabinet into place.

1. Ensure that the cabinet contains no power or battery modules.

2. Locate the four plastic caps covering the caster bolts. They are

FOR U.S. INSTALLATIONS, READ THIS IMPORTANT NOTE!

This table lists the AWG and mm2 wire size for each circuit breaker size shown on the wiring diagrams. The minimum recommended circuit breaker sizes for each model and voltage application are listed on the wiring diagrams. Conductor sizes shall be no smaller than the 75°C wire size based on the ampacities given in Table 31016 of the National Electrical Code, ANSI/NFPA 70-1999, and article 220. All circuit conductors, including the neutral and equipment grounding conductors, must be the same size (ampacity) wire. 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 code requirements.

Bypass Switches

Bypass switches are available in two types: Make-Before-Break (MBB) and Break-Before-Make (BBM).

An MBB switch makes a new connection before it breaks the original connection. For example, if you turn an MBB switch from UPS to LINE, the bypass switch connects the load to AC input power before disconnecting the load from UPS output power. (As noted in Figure 37 on page 47, MBB switches may not be used in certain system configurations.)

A BBM switch breaks the original connection before it makes a new one. If you turn a BBM switch from UPS to LINE, the switch disconnects the load from UPS output power before connecting the load to AC input power.

The bypass switch has four positions as described in Table 3.

NOTE In the UPS or LINE position, AC input power is still connected to the input terminals inside the UPS.

Table 3. Bypass Switch Positions

Switch Position Description

LINE Connects the load directly to AC input power and disconnects UPS output. AC input power is still

connected to the UPS input.

OFF Disconnects the load from the UPS output power and AC input power, as well as AC input power

to the UPS input.

UPS Connects the UPS output to the load.

SERVICE Like the LINE position, SERVICE connects the load directly to AC input power and disconnects

UPS output. However, because SERVICE also disconnects AC input from the UPS, this is

the appropriate position for UPS maintenance or repair.

To disconnect AC input power during maintenance or service, turn the bypass switch to the SERVICE position. For MBB switches, you must press the red button beside the switch before you can change the switch position.

There are six bypass switch models available for the Powerware 9170 UPS as specified in Table 4.

UPS Installation with an External Bypass Switch

A R N I N G

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

C A U T I O N

To prevent electrical shock or damage to the equipment, verify that the Powerware 9170 UPS is OFF before you remove the entrance panel. The circuit breaker or disconnect switch must also be off at the AC input service panel. Also, turn OFF the AC disconnect and bypass switches before you connect any wires to the bypass switch terminal strip.

1. Mount the bypass switch within sight of the UPS. If you do not have a Powerware bypass switch or the fuse box or panel is out of sight, you must install a separate disconnect switch next to the UPS.

The bypass switch should be mounted securely to a sturdy surface. You may need to turn the cabinet 90 degrees (on its side) to enable operator access to the switch handle.

2. Remove the six screws in the bypass switch front panel and remove the panel. Remove any packing material inside the bypass switch.

Remove knockouts in the bottom of the bypass switch for AC Line Input, AC to UPS Input, AC from UPS Output, and AC to the UPS load.

UPS STARTUP

This section provides step-by-step instructions for starting your Powerware 9170 system. Follow these procedures closely to avoid potential damage to your equipment or the UPS and to protect yourself and others from hazardous operating conditions.

 This UPS contains its own energy source (batteries). The output receptacles may

carry hazardous voltage even when the UPS is not connected to an AC supply. When AC input voltage is present, the Powerware 9170 system can provide output voltage even though its batteries are disconnected. To confirm that there is no UPS output voltage, always disconnect all of the AC input sources and unplug all strings of internal battery modules; if the UPS has one or more separate battery cabinets, open the DC disconnect switch in each battery cabinet or unplug all battery strings in each battery cabinet.

 To reduce the risk of fire or electric shock, install this UPS in a temperature and

humidity controlled, indoor environment, free of conductive contaminants. Ambient temperature must not exceed 40°C (104°F). Do not operate near water or excessive humidity (95% max).

Balancing Receptacle Loads

For Powerware 9170 UPS models with low-voltage output receptacles, it is recommended to divide loads between upper and lower receptacles as equally as possible. (In some configurations, each set of receptacles is limited to one half of the total UPS capacity.) Whether the cabinet has one panel containing eight receptacles, two panels containing 16 receptacles, or three panels containing 24 receptacles, you should try to supply half of the UPS output through the upper half of the receptacles (X1) and the other half through the lower half of the receptacles (X2), as shown in Figure 44.

OPERATION

The Powerware 9170 UPS operates in several different modes. Normally it operates under internal control, called Auto mode, to automatically protect loads connected to it. It also functions under operator control to enable manual override should servicing or testing be required.

Figure 45 is an illustration of the operating modes. In Auto mode, the UPS automatically switches between modes depending on line and load conditions.

Double Conversion (Line Conditioning)

Battery Off

Figure 45. UPS Operating Modes Under Auto Mode Control

Double Conversion mode produces output power from the internal DC bus. The AC input power is rectified and boosted to supply this DC bus. The UPS switches automatically to and from Battery mode with no interruption (0 ms transfer time) as AC input power drops and returns. Batteries are charged in this mode.

Battery mode produces power from the batteries to supply the internal DC bus.

Internal Bypass (Bypass) mode shunts power flow around the DC/AC internal circuitry to keep the output powered with no line conditioning. Electromagnetic interference (EMI) and surge circuitry still protect the loads from voltage spikes and noise.

Internal Bypass

Powerware® 9170 User's Guide  LTM-1344 B Uncontrolled Copy

Operation

The High Efficiency (H.E.) mode is a user-programmable automatic mode of operation. This mode allows power to flow through the internal UPS bypass path for as long as AC input stays within the user-defined setpoints. If the input voltage or frequency deviates beyond these setpoints, the Powerware 9170 system transfers to the Double Conversion mode of operation. Complete loss of input voltage causes the UPS to transfer to Battery mode. While in H.E. mode, the Powerware 9170 system provides passive EMI filtering in the power path.

Off mode turns off the output and most internal circuitry. Within this mode, another mode (Sleep) turns off all internal circuitry when AC line is not present and battery voltage drops to a low threshold. If AC input voltage is not present in Off mode, the user can direct the UPS to enter Sleep mode by selecting the Battery Protect (BP) feature. When AC input voltage returns in the Off mode (caused by a low battery alarm condition), the UPS automatically recovers and, if the Auto Restart parameter is enabled, switches to Double Conversion. Auto Restart is enabled as a factory-default.

The UPS will not automatically recover from the Sleep mode, regardless of the state of the Auto Restart parameter.

Removing Input Power

Always put the Powerware 9170 UPS into the Off mode before removing input power. Powerware 9170 system batteries will discharge if the input line voltage is disconnected or turned off without first turning off the Powerware 9170 UPS.

If the input power source will be disconnected or turned off for more than a day or two, you should put the UPS into Sleep mode. Do this by turning the UPS off, removing AC input power, and then pressing the On button and selecting Battery Protect (BP). Sleep mode allows the UPS to remain unpowered for up to six months without having to remove or recharge batteries.

Failure to properly power down the Powerware 9170 UPS could permanently damage any installed batteries. Also, if batteries become severely discharged, the UPS might not start immediately when input power is restored.

Turning the UPS On

If the UPS has been turned off, press the ON button through the front panel display to turn the UPS on again.

If the UPS has been manually set to operate in Bypass or Battery mode, change the System mode menu selection (menu 2) to Auto to return to normal Auto mode operation.

Operation

NOTE The UPS will not start operating if AC input voltage or frequency is beyond acceptable limits or if the system mode selection is set to Battery. The UPS can not go directly from Off to Battery.

Using the Front Panel Display

The front panel display shows several important things (see Figure 48). The numbers in the upper left corner (for example, 3 19) are the display location within the operating menu structure. The word in the top center (for example, USER ) is the security level, which allows various operating parameters to be changed.

3 19 USER #2 Wout watts 1.87 KW Slot Top ESC

The number in the upper right corner (for example, #2) identifies the cabinet slot (numbered from the top down) for a specific power module's parameters. #0 is defined as System, enabling you to observe overall system operation.

One or two triangles at the right of the display tells you which arrow buttons are active for moving to various parameters within a menu level. See Figure 50 on page 68 for the complete system menu.

The words or symbols in the bottom line of the display define the function of the three buttons below the display. In Figure 48, Slot (button A) enables you to observe the operation of a specific power module (the module in slot #2, in this case) or the overall system (selected as slot #0). Top (button B) takes you to the top item in the current menu level (in this case, 3 1). And ESC (button C) enables you to move out of the current menu level (in this case, to menu 3).

During normal operation, the display appears as shown in Figure 49. Md: indicates the current UPS operating mode and St: indicates the operational state. The number of power modules (M) and number of battery module strings (B) that are currently online, and the total number of module slots in the cabinetfor example, M4-B7-12is shown in the upper right corner of the display. (The count of battery strings does not include additional battery strings contained in connected external battery cabinets.)

Dedicated Input Signals

Emergency Power-Off (EPO): Connection to a facility Emergency Shutdown

switch provides a method for emergency Powerware 9170 system shutdown. Opening this connection creates an immediate shutdown of the Powerware 9170 UPS output.

Bypass: The signal from an external bypass switch, to isolate the

Powerware 9170 system for maintenance purposes, tells the UPS to go into Internal Bypass mode.

On-Generator: An external signal that the input power is being supplied

by a generator tells the UPS to accept wider input power frequency limits.

See Figure 21 on page 31 and Figure 24 on page 34 to make the connection for all dedicated input signals.

DB-9 Port Pin Functions

Table 10 explains the functions of the pins on the Powerware 9170 DB-9 port. This port is on the Powerware 9170 UPS rear panel, as shown in Figure 42 on page 52.

MAINTENANCE

Routine Maintenance

NOTE Technicians must observe important safety precautions while performing these

checks.

The Powerware 9170 system is designed to provide years of trouble-free operation. Its internal control system checks the batteries and inverter periodically to ensure reliable operation. In fact, you'll probably find that your Powerware 9170 system requires less maintenance than any of your other computer peripherals.

Nevertheless, the Powerware 9170 UPS and optional external battery cabinets do require some attention to assure continued reliable service. Powerware recommends that you schedule preventive maintenance checks at least every six months. At these checks, the service technician should follow Powerware's recommended maintenance schedule, which includes the following items:

 Check operating environment for clean, cool, dry conditions.  Inspect and clean the unit.  Check operation of fans (power modules).  Check and tighten all connections.  View and record the alarm and inverter logs.  Check the batteries.  Check the displayed UPS readings against actual measurements and

recalibrate if necessary.

 Perform a system test.  Check and record the values of the parameters in menu 3 online and

on battery.

 Check the MOV surge suppression pack.

For more information on preventive maintenance checks, contact your service representative.

Maintenance

Storage Temperature

Store the Powerware 9170 battery modules (in the unit or battery cabinet) at 20 to +40°C (4 to +104°F). Batteries will have a longer shelf life if they are kept below +25°C (+77°F). The Powerware 9170 UPS or battery cabinet without batteries may be stored at 40 to +60°C (40 to +140°F).

External Bypass Switch (Make-Before-Break Only) Operation

Before turning the Powerware MBB bypass switch, you must press the red button located next to the handle. This button serves two purposes. It sends an electrical signal to the UPS to switch to the internal Bypass mode (if it is not already operating in that mode). The button also operates a mechanical interlock, to prevent the switch from being turned without first signaling the UPS.

NOTE When the red button is released, the UPS remains in its internal Bypass mode and must be manually returned to the Auto mode by selecting that mode on the front panel display.

Battery Replacement

The Powerware 9170 hotswappable feature allows you to replace the battery modules easily without disconnecting the load or damaging the batteries.

NOTE The Powerware 9170 UPS will operate with uncharged (or no) batteries, but will have limited (or no) battery backup capability. Backup protection requires at least three battery strings for every four power modules.

Use the following procedure to replace battery modules in pairs.

1. Remove the front panel bezel(s) covering the battery modules

2. Grasp the battery module handle and press down on the latch

3. Pull the module out approximately 7 (17 cm) to the secondary

4. Press down on the secondary stop release, pull the module out further, and support the module weight with your second hand as you remove the module from the cabinet. Remove the battery module beside the first in a similar manner.

5. After removing a pair (one string) of battery modules, install a replacement pair. Replacements may be installed in empty cabinet slots before removing original battery modules.

6. When all desired battery modules have been replaced, reinstall the front panel bezel(s).

Power Module Replacement

The Powerware 9170 hotswap feature allows you to replace a power module easily without disconnecting the load or damaging the UPS.

NOTE The UPS may switch to internal bypass if the remaining power modules are insufficient to supply the required power. If empty slots exist, install replacement modules before removing original ones.

Use care in removing and installing power modules. To remove a power module:

1. Loosen the thumbscrew on the module handle. Press down on the latch release at the center of the module handle and pull the handle down.

As the handle fully extends, the module disconnects. Slide the module slowly out of the cabinet.

2. Use two hands to support the module. When fully extended, lower the front down slightly and lift the rear edge over the safety stop on the center support rail.

3. Treat the original and replacement modules with care to avoid damaging connectors or internal circuitry. Label the original module with masking tape or some other identifier. Record the serial number of the replacement module for your warranty.

Table 17. Frequently Asked Questions

Question: How do I... " Answer

Turn the UPS on? Verify that all power modules are securely plugged into the cabinet, and each

module handle is latched. Also confirm that the DC disconnect button on the back of the external battery cabinet is closed (pulled out). Turn the optional external bypass switch to the LINE or UPS position. Refer to the front panel display and press the button labeled ON. (If On/Off control is passwordprotected, enter the user password: 0377.) Confirm the selection by pressing the button labeled Yes. After a few seconds, the green LED illuminates to signal the UPS is operating and producing power.

Turn the UPS off? Refer to the front panel display and press the button labeled OFF. Confirm the

selection by pressing the button labeled Yes. (If On/Off control is passwordprotected, enter the user password: 0377.) In the event of a front panel display failure, you can turn the unit on or off using a computer connected to the communication port. In an emergency or when the above two methods fail to turn the unit off, remove the front cover bezels, and unlatch and pull the handles of all power modules out at least one inch (2.5 cm) to turn off the power control circuitry. If your UPS has external battery cabinets, press the large, red DC disconnect button on the back of the battery cabinet nearest to the UPS cabinet.
