Introduction

The Dellt Tower uninterruptible power system (UPS) protects your sensitive electronic equipment
from basic power problems such as power failures, power sags, power surges, brownouts, and line noise.

Power outages can occur when you least expect them and power quality can be erratic. These power
problems have the potential to corrupt critical data, destroy unsaved work sessions, and damage
hardware — causing hours of lost productivity and expensive repairs.

With the Dell Tower UPS, you can safely eliminate the effects of power disturbances and guard the
integrity of your equipment. The UPS's flexibility to handle an array of network devices makes it the
perfect choice to protect your LANs, servers, workstations, and other electrical equipment.

Figure 1 shows the Dell Tower UPS.

Introduction

Providing outstanding performance and reliability, the UPS's unique benefits include:

S Buck and Boost voltage regulation that ensures regulated voltage to your load by correcting voltage

fluctuations.

S Start‐on‐battery capability for powering up the UPS even if utility power is not available.

S Maintenance is simplified by allowing the safe replacement of batteries without powering down the

UPS.

S Extended runtime with an optional External Battery Module (EBM) for 1000–1920W UPS models.

S Two standard communication ports (USB and DB-9 serial port).

S Optional Dell Network Management Card with enhanced communication capabilities for

increased power protection and control.

S Network transient protector that guards your network communications equipment from surges.

S Advanced power management with the Dell UPS Management Software for graceful shutdowns

and power monitoring.

S Sequential shutdown and load management through separate receptacle groups called load

segments.

S Firmware that is easily upgradable without a service call.

S Backed by worldwide agency approvals.

Safety Warnings

CAUTION: Before performing the procedures in this document, read and follow the safety instructions and

important regulatory information in your Safety, Environmental, and Regulatory Information document.

IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS

This manual contains important instructions that you should follow during installation and
maintenance of the UPS and batteries. Please read all instructions before operating the equipment and
save this manual for future reference.

DANGER:

avoided, will result in death or serious injury:

S This UPS contains LETHAL VOLTAGES. All repairs and service should be performed by

AUTHORIZED SERVICE PERSONNEL ONLY. There are NO USER SERVICEABLE
PARTS inside the UPS.

WARNING:

avoided, could result in death or injury:

S This UPS contains its own energy source (batteries). The output receptacles may carry live voltage

even when the UPS is not connected to an AC supply.

S Do not remove or unplug the input cord when the UPS is turned on. This removes the safety

ground from the UPS and the equipment connected to the UPS.

S To reduce the risk of fire, connect only to a circuit provided with branch circuit overcurrent

protection with an ampere rating in accordance with the National Electrical Code
ANSI/NFPA 70 or your local electrical code:

UPS Output Power 120V 208V 230V

500W 15A — 15A

1000W 15A — 15A

1500W (at 100V)

1920W

Observe the following instruction to help prevent an imminently hazardous situation which, if not

Observe the following instructions to help prevent a potentially hazardous situation which, if not

(NEC®),

20A — 15A

S 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% maximum).

S Unpacking the cabinet in a low-temperature environment may cause condensation to occur in and

on the cabinet. Do not install the cabinet until the inside and outside of the cabinet are absolutely
dry (hazard of electric shock).

S If the UPS requires any type of transportation, disconnect the internal UPS batteries before

transporting (see page 51).

CAUTION:

avoided, may result in minor or moderate injury or in property damage incidents:

Observe the following instructions to help prevent a potentially hazardous situation which, if not

S For PLUGABLE EQUIPMENT, the power outlet shall be installed near the equipment and shall

be easily accessible.

S Servicing of batteries should be performed or supervised by personnel knowledgeable about

batteries and the required precautions. Keep unauthorized personnel away from batteries.

S Batteries can present a risk of electrical shock or burn from high short-circuit current. The

following precautions should be observed: 1) Remove watches, rings, or other metal objects; 2) Use
tools with insulated handles; 3) Wear rubber gloves and boots; 4) Do not lay tools or metal parts on
top of batteries; 5) Disconnect the charging source prior to connecting or disconnecting battery
terminals.

S Determine if the battery is inadvertently grounded. If inadvertently grounded, remove the utility

source from the ground. Contact with any part of a grounded battery can result in electrical shock.
The likelihood of such shock can be reduced if such grounds are removed during installation and
maintenance (applicable to equipment and remote battery supplies not having a grounded supply
circuit).

S ELECTRIC ENERGY HAZARD. Do not attempt to alter any battery wiring or connectors.

Attempting to alter wiring can cause injury.

S Replace batteries with the same number and type of batteries as originally installed in the UPS.

S Proper disposal of batteries is required. Refer to your local codes for disposal requirements.

S Never dispose of batteries in a fire. Batteries may explode when exposed to flame.

S Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the skin and

eyes and may be extremely toxic.

S The 1000W and 1920/1500W UPS may be connected to a maximum of one External Battery

Module (EBM).

S To avoid interference and flicker, it is recommended that CRT monitors be placed at least one foot

away from the UPS.

Inspecting the Equipment

If any equipment has been damaged during shipment, keep the shipping cartons and packing materials
for the carrier or place of purchase and file a claim for shipping damage. If you discover damage after
acceptance, file a claim for concealed damage.

To file a claim for shipping damage or concealed damage: 1) File with the carrier within 15 days of
receipt of the equipment; 2) Send a copy of the damage claim within 15 days to your service
representative.

NOTE:

Check the battery recharge date on the shipping carton label. If the date has passed and the batteries

were never recharged, do not use the UPS. Contact your service representative.

Unpacking the System

CAUTION: Unpacking the cabinet in a low-temperature environment may cause condensation to occur in and

on the cabinet. Do not install the cabinet until the inside and outside of the cabinet are absolutely dry (hazard
of electric shock).

CAUTION: The cabinet is heavy (see page 55). Use caution to unpack and move the cabinet.

To unpack the system:

1 Unpack your system and identify each item (see Figure 2).

Place the cabinet in a protected area that has adequate airflow and is free of humidity, flammable
gas, and corrosion.

2 Discard or recycle the packaging in a responsible manner, or store it for future use.
