AboutThisManual
OVERVIEW
This manual is intended for use by the customer for site preparation, by the customer’s
electrician to install the HA3000 20-80 kVA series Uninterruptible Power System (UPS),
and by the Digital Services Engineer to ensure proper installation before performing
the startup procedures. It provides site preparation information and instructions for
receiving, handling, storing, and installing the UPS for the customer and the customer’s
electrician. The installation must be completed before calling Digital Services to
perform the startup procedures. Incomplete installation will result in startup
delays.
WARNING
The HA32B UPS Battery Cabinet contains batteries that are wired together to
produce a high voltage. Even with no external connections, hazardous voltage
exists inside the UPS Battery Cabinet that can cause severe burns or death
upon contact.
The manual covers the following topics:
• Chapter 1 contains a checklist of the responsibilities of the customer, customer’s
electrician, trucker/mover/rigger, and Digital Services during site preparation,
delivery/handling, installation, and startup of the HA3000 series UPS.
• Chapter 2 contains site preparation information for the HA32A UPS cabinet, the
HA32B UPS Battery Cabinet, the HA32C/D/E UPS Auxiliary Cabinet, the HA33D/F
UPS CSA Cabinet, and the HA32J/K UPS Distribution Cabinet.
• Chapter 3 contains information for receiving and handling the HA3000 series
equipment cabinets.
• Chapter 4 contains the installation procedures for the HA32A UPS cabinet, the
HA32B UPS Battery Cabinet, the HA32C/D/E UPS Auxiliary Cabinet, the HA33D/F
UPS CSA Cabinet, the HA32J/K UPS Distribution Cabinet, the HA320-AA/AB
Remote Status Panel, the HA320-A3 Remote Alarm Panel, the HA320-B1 Smoke
Detector, and the HA320-C2 DC Ground Fault Detector.
• Appendix A contains electrical considerations for the HA32A UPS cabinet.
• Appendix B contains specification tables for the HA3000 series components.

INSTALLATIONREFERENCECHECKLISTS
1.1 CUSTOMER RESPONSIBILITIES
The following sections contain checklists of the responsibilities of the customer during
site preparation and delivery/handling of the HA3000 series UPS.
1.1.1 Site Preparation
The customer’s responsibilities during site preparation are listed below.
Check Off Function Task
Electrical
Connections Obtain an electrician to perform the electrical connections that are described in Chapter 4.
Site Selection Select the area where the HA3000 series UPS will be
installed. Where it is located will have a bearing on
the electrical installation cost and installation time.
NOTE: It is highly recommended that the HA3000
series UPS be installed in a computer room
environment with a raised floor.
Physical Size and
Weight Obtain the size and weight information on the HA3000
series cabinets that are to be installed. Refer to the
HA3000 20-80 kVA Uninterruptible Power System
Installation Drawings (EK-HA32X-ID) or to Chapter 2
in this manual.
Physical Placement Determine the exact physical placement of the
cabinets. The cabinet dimensions and service
clearances must be taken into consideration. The
following is a list of the minimum service clearances
required.
Rear - 60.96 cm (24 in)
Front - 121.92 cm (48 in)
Side - 60.96 cm (24 in) on each end of the cabinet
configuration
Top - 91.44 cm (36 in)
NOTE: Local codes may require more clearance.
Floor Loading Ensure that the floor can support the total
configuration weight. If there is any question in this
regard, a structural engineer should be consulted.

1–2 INSTALLATION REFERENCE CHECKLISTS
Check Off Function Task
Configuration Layout Plan the configuration layout using the following
placement order (left to right): UPS Battery Cabinet(s),
UPS cabinet, UPS Auxiliary Cabinet, UPS CSA
Cabinet, and UPS Distribution Cabinet.
Floor Marking Mark the outside dimensions of the cabinet
configuration and the floor cutouts on the floor with
tape so that placement and any floor cutouts will be in
the correct place.
Floor Cutouts On a raised floor, ensure that floor tile cutouts are
provided for cool air supply and cabling. Refer to the
HA3000 20-80 kVA Uninterruptible Power System
Installation Drawings (EK-HA32X-ID) for the cable
entry areas on the UPS cabinet, the UPS Battery
Cabinet, and the UPS Distribution Cabinet.
CAUTION: If perforated tiles are used for cooling,
ensure that air restricting baffles are not installed
beneath them.
Inside Delivery
Route Ensure that there is an unobstructed inside delivery
path to the final installation position. Ensure that
elevators, ramps, and flooring along this path can
handle the equipment weights and dimensions.
1.1.2 Delivery/Handling
The customer’s responsibilities during delivery/handling are listed below.
Check Off Function Task
Site Delivery
Coordination Assist Digital Services in assuring proper delivery and placement of the HA3000 series cabinets.
Configuration
Assembly Assist Digital Services in removing the appropriate side skins and cover plates before the cabinets are in
their final position.
Final Assembly Assist Digital Services in replacing all exterior skins.
Check to ensure that all cabinets are complete.

INSTALLATION REFERENCE CHECKLISTS 1–3
1.2 TRUCKER/MOVER/RIGGER RESPONSIBILITIES
The trucker/mover/rigger’s responsibilities during delivery/handling are listed below.
Check Off Function Task
Inside Delivery and
Handling Deliver the HA3000 series cabinets from the padded
van to the final resting place at the customer’s site.
Follow the handling instructions in Chapter 3.
Caster Assembly
Removal Remove the yellow caster assemblies beneath each
cabinet after the cabinets have been moved to their
final resting place.
1.3 ELECTRICIAN RESPONSIBILITIES
The following sections contain the responsibilities of the electrician during the
installation of the HA3000 series UPS. The electrician should refer to the HA3000
20-80 kVA Uninterruptible Power System Installation Drawings (EK-HA32X-ID) and to
the procedures in Chapter 4 when performing the actual installation. All electrical site
wiring must comply with the National Electrical Code (ANSI/NFPA 70) and with local
codes as applicable.
1.3.1 HA32A UPS Cabinet
The electrician’s responsibilities during the installation of the HA32A-xx UPS cabinet are
listed below.
Check Off Function Task
Cable Entry/Exit Perform the cable knockouts and provide the fittings
and conduits for this cabinet. Bottom or right-side
cable entry is possible. Refer to Figure 2–1, Figure 2–2,
and Figure 2–3.
Input Conductor
Sizing Determine the input conductor sizing for the UPS. The circuit rating needs to be matched to the input circuit
breaker for the unit being installed. Refer to Table 2–1
for the input circuit breaker ratings for the different
UPS models.
MAINS1 Input
Conductors (supplied
by the electrician)
Provide four wires for the MAINS1 input; three phase
conductors and a ground. If only one power source
is to be used for the MAINS1 and MAINS2 inputs,
the MAINS1 and MAINS2 busbars must be jumpered
together using the correct gauge wire.
MAINS2 Input
Conductors (supplied
by the electrician)
Provide five wires for the MAINS2 input; three phase
conductors, a neutral1(all four of equal ampacity), and
a ground. If only one power source is to be used for
the MAINS1 and MAINS2 inputs, the MAINS1 and
MAINS2 busbars must be jumpered together using the
correct gauge wire. If no neutral1is available from
the building distribution system (for example, DELTA
only service entrance), a UPS Auxiliary Cabinet with
an input isolation transformer may be used to derive a
neutral for the UPS cabinet.
1If an HA32A-Cx cabinet is being installed, a neutral conductor is not required.

1–4 INSTALLATION REFERENCE CHECKLISTS
1.3.2 HA32B UPS Battery Cabinet
The electrician’s responsibilities during the installation of the HA32B-xx UPS Battery
Cabinet are listed below.
Check Off Function Task
Cable Entry/Exit Perform the cable knockouts and provide the fittings
and conduits for this cabinet. Refer to the HA3000
20-80 kVA Uninterruptible Power System Installation
Drawings (EK-HA32X-ID) for cable entry/exit location.
Power and Ground
Connections
(supplied by the
electrician)
Provide three power cables and crimp terminals;
positive, negative, and ground. The battery wiring
should be sized to keep the total cable voltage drop to
less than 0.5 Vdc at the current shown in Table 4–2.
Cable Connections Connect the cables from the dc output busbars in the
UPS Battery Cabinet (Figure 4–4) to the dc input
busbars in the UPS cabinet (Figure 4–1). Correct
dc polarity must be observed when making these
connections.
Control Wire
Connections
(supplied by the
