this manual. Failure to comply may invalidate the warranty and cause property damage and/or personal injury.
Location Warnings
3
Install the UPS system in a controlled indoor environment, away from moisture, temperature extremes, flammable liquids and gasses, conductive •
contaminants, dust and direct sunlight.
Install the UPS system in a • level, structurally sound location.
4
The UPS system is extremely heavy; be extremely careful when moving or lifting the unit.•
Operate the UPS system at indoor temperatures between 32° F and 104° F (0° C and 40° C) only. For best results, maintain indoor temperatures •
between 62° F and 84° F (17° C and 29° C).
Leave adequate space around all sides of the UPS system for proper ventilation. Do not block, cover or insert objects into the external ventilation •
5
openings of the cabinet.
Do not place any object on the unit, especially containers of liquid.•
Do not mount the unit with its front or rear panel facing down (at any angle). Mounting in this manner will seriously inhibit the unit’s internal •
cooling, eventually causing product damage not covered under warranty.
6
Do not install the UPS system near magnetic storage media, as this may result in data corruption. Keep all recorded magnetic media a minimum •
of 60 cm (24 inches) away from the UPS system.
Do not attempt to stack the UPS system. Attempting to stack the UPS system may cause permanent damage and create a potential for serious •
personal injury.
7
The casters are designed for minor position adjustments within the final installation area only. The casters are not designed for moving the UPS •
system over longer distances.
The casters are not designed to provide long-term support for the UPS system after final installation. Use the levelers to provide long-term •
support.
8
When moving the UPS system, push from the front or rear, not from the sides.•
Do not attempt to unpack or move the UPS system without assistance.•
Connection Warnings
9
The power supply for the UPS system must be 3-phase rated in accordance with the equipment nameplate. It also must be suitably •
grounded and wired according to all applicable national and local electrical wiring standards, codes and regulations.
The UPS system contains hazardous high voltages that have the potential to cause personal injury or death from electric shock.•
10
11
12
The UPS system has its own energy source (battery – internal and/or external). The output terminals may be live even when the UPS system is •
not connected to an AC supply.
If the UPS system receives power from a motor-powered AC generator, the generator must provide clean, filtered, computer-grade output.•
Use of this equipment in life support applications where failure of this equipment can reasonably be expected to cause the failure of the life •
support equipment or to significantly affect its safety or effectiveness is not recommended. Do not use this equipment in the presence of a
flammable anesthetic mixture with air, oxygen or nitrous oxide.
The UPS system is designed to power modern computer loads and associated peripheral devices. Do not use the UPS system to power pure •
inductive or capacitive loads.
Input and output wiring should be performed by trained, qualified electricians only.•
Due to high leakage current, a proper earth ground connection is essential before connecting the AC supply.•
Isolate the UPS system before working on the circuit. An easily accessible disconnect device should be incorporated in the fixed wiring. The •
disconnect device must disconnect all line conductors simultaneously when opened.

Read Section 2 – Important Safety Instructions Before Installation
5-1 Preparation
The UPS system must be installed in a structurally sound area with a level floor that is able to bear the weight of the UPS system, any external
battery cabinet and other equipment that will be installed nearby. The installation site should also have a dedicated AC circuit available that is
compatible with the UPS system’s input requirements. (See Section 12 – Specifications for details on input requirements and floor loading
requirements.) Before unpacking the unit, you should transport the shipping container closer to the final installation site to minimize the distance
you will need to move the unit after the protective shipping container has been removed. If you plan to store the UPS system for an extended
period before installation, follow the instructions in Section 13 – Storage and Service. (Unpacking and storage instructions are also printed on the
“Unpacking and Storage Instructions” sheet secured to the shipping container.) Warning: Do not attempt to unpack or move the UPS system
without assistance.
5-2 Unpacking

Inspect the shipping container(s) for visible damage. If you •
determine that the unit has been damaged during shipping, contact
Tripp Lite for assistance. Do not attempt to use the UPS system if
it has been damaged or mishandled.
2
Confirm that the shipping container is upright and use a •
screwdriver to remove its top panel, front panel and back panel.
Also remove the plastic wrap and interior cushioning material.
Confirm that the model name and rating at the rear of the cabinet
match the unit you ordered. Examine the cabinet for any damaged
or loosened parts. Confirm that the shipping container includes the
accessories that ship with the unit. The UPS system should include
an RS-232 serial cable, a parallel redundancy cable, a remote EPO
wiring connector, a dry contact input connector (4 contacts), a dry
contact output connector (12 contacts) and a software CD-ROM. If

sure the voltmeter’s probes touch the metal contacts inside the
battery pack’s connectors. The battery pack’s acceptable DC
voltage range is between 220V and 280V DC (nominal 240V DC).
If several voltmeter tests yield results outside the acceptable DC
voltage range, contact Tripp Lite for assistance in determining the
possible causes of the incorrect voltage reading before proceeding.

Connect the • black cable for each internal battery pack to the
12
nearest black connector located inside the UPS system’s battery
compartment. Connect the red cable for each internal battery
pack to the nearest red connector located inside the UPS system’s
battery compartment. Warning: Observe proper polarity by
connecting negative to negative (black to black) and positive
to positive (red to red). Failure to observe proper polarity will
damage the UPS system and create a serious risk of personal
injury and property damage.

Replace the battery access bezels.•
14
Follow the proper procedure to restart the UPS and re-transfer the •
critical load to protected power.
Note: If you need to remove or replace internal battery packs, modify
steps 6 and 7 by removing and/or replacing the existing internal battery
packs, as required.

7-1 Wiring Warnings
3
De-energize all input and output power sources of the UPS system before installing cables or making electrical connections.•
Use flexible cable of sufficient length to permit UPS system servicing. The maximum cable length is 10 m (32.8 ft).•
Use ferrule caps to cover termination cables and prevent frayed ends from shorting on the UPS system terminal block.•
4
Use cabling rated VW-1, FT-1 or better.•
Use cable sleeves and connector clamps.•
The neutral conductor must be the same size as the current conductors.•
Tighten all connections with a torque of at least 3.95 N·m (35 in·lb)•
5
Confirm that all cables are marked correctly according to their purpose, polarity, phase and diameter.•
If the UPS system’s input/output power source is wye-wye, then “Neutral” and “Ground” must not be connected.•
If the input power source has VNG>0, install a grounded wye secondary isolation transformer with a properly bonded neutral to ground before •
6
the UPS system and input power source.
For equipment requiring a neutral connection to an IT power distribution system that requires neutral isolation upon disconnect, the disconnect •
device must be a four-pole device and must disconnect all line conductors and the neutral conductor. If a disconnect device interrupts the neutral
conductor, it must simultaneously interrupt all line conductors.
7
Allow the batteries to charge uninterrupted for 24 hours after the initial wiring connection.•
Observe proper polarity by connecting negative to negative, positive to positive and normal “N” to normal “N”. Failure to observe proper •
polarity will damage the UPS system and create a serious risk of personal injury and property damage.
Observe proper phase by connecting R to R, S to S, T to T and N to N. Source power phase rotation must be verified as RST before powering •
8
the UPS. Failure to observe proper phase will damage the UPS system and create a risk of personal injury and property damage.
All wiring should be performed by a qualified electrician, in accordance with the warnings in this manual and all applicable
electrical and safety codes. Incorrect wiring may damage the UPS system severely and cause serious personal injury and
property damage. Read Section 2 – Important Safety Instructions before proceeding.
7-2 Wiring Preparation
De-energize all input and output (AC and DC) of the UPS system and external battery cabinet (if present).•
9
Mark all cables according to their correct purpose, polarity, phase and diameter.•
Review the diagrams in • Section 7-3 and Section 7-4 to familiarize yourself with the terminal blocks.
Consult the table in • Section 7-5 to find the correct electrical input/output characteristics for the UPS system.
10
Note: If the UPS system’s input/output power source is wye-wye, then “Neutral” and “Ground” must not be connected. If the input power source
has VNG>0, install an isolation transformer before the UPS system and input power source, then connect the UPS system’s “Neutral” and
“Ground” together.
