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.

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)

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

Floor Anchor Kit Installation

An optional floor anchor kit (ASY-0548) is available for all sizes of the
Powerware 9170 UPS. The kit helps to stabilize the UPS or battery
cabinet in the event of accidental bumps or small floor movements. Any
testing to specific seismic requirements is the responsibility of the
customer.

The floor anchor brackets, shipped separately from the UPS and battery
cabinet, should be attached inside the lower front and rear edges of the
cabinet before installing power and battery modules, and before making
connections to the intended power source.

Use mounting hardware supplied with the floor anchor kit to attach the
brackets to the UPS or external battery cabinet (see Figure 12). The
customer is responsible for specifying and supplying floor mounting
bolts.

Installation Setup

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

3. Pry the caps out of the bolt access holes.

4. Use a 1/2 hex-style socket wrench to turn each of the four

bolts clockwise. Doing so lowers the casters to allow the cabinet
to roll on the casters.

5. After rolling the cabinet to its intended position, turn all four
caster bolts counter-clockwise until the cabinet rests on the
floor. Place a plastic cap into each bolt access hole.

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.

After properly positioning and leveling the cabinet, insert power and
battery modules into the rack as described in UPS Startup" on page 49.
